Python vs Pharo

Python is widely regarded as an easy language for beginners. But did you know that there’s a much easier language, one that has far greater capabilities? It’s called Pharo, a modern variant of Smalltalk. Let’s compare the two…

Simplicity, Conciseness, and Elegance

Pharo is much, much simpler than Python. It has all of six reserved words. The complete syntax fits on a post card!

You sure as hell can’t do that with Python!

You can learn the entire language in 15 minutes: Learn Smalltalk with ProfStef. You sure as hell can’t do that with Python!

Pharo is astonishingly concise and elegant. Here’s a sampling of wonderful one-liners:

"Compute difference in days between two dates"
('2014-07-01' asDate - '2013/2/1' asDate) days
"Set up an HTTP server that returns the current timestamp"
(ZnServer startDefaultOn: 8080) 
  onRequestRespond: [ :request | 
    ZnResponse ok: (ZnEntity with: DateAndTime now printString) ]
"Split a string on dashes, reverse the order of the elements and join them using slashes"
$/ join: ($- split: '1969-07-20') reverse
"Sum of the primes up to 64"
(Integer primesUpTo: 64) sum
"Extract a Unix format timestamp from the 5th to 8th byte of a byte array given in hex"
DateAndTime fromUnixTime:
  ((ByteArray readHexFrom: 'CAFEBABE4422334400FF') 
      copyFrom: 5 to: 8) asInteger
"Return the weekday of a date"
'2013/5/7' asDate dayOfWeekName
"Save the HTML source of a web page to a file"
'' asUrl saveContentsToFile: 'page.html'
"Count the number of, or show the leap years between two years"
(1914 to: 1945) count: [ :each | Year isLeapYear: each ].
(1895 to: 1915) select: [ :each | Year isLeapYear: each ].
"Encode the same string using Latin1, UTF-8 and UTF-16"
#(latin1 utf8 utf16) collect: [ :each | 
  (ZnCharacterEncoder newForEncoding: each)
    encodeString: 'Les élèves Français' ]

In Python, it’s almost impossible to do anything in one line.

Off-side Rule

Python’s use of indentation as syntax is highly controversial. It’s the main reason why so many developers hate Python. One issue is that an accidental misalignment of code can cause a very subtle and difficult-to-find bug. Who can claim that accidents never happen?

Pharo doesn’t suffer from this malady.

Object-oriented Programming

Pharo is purely object-oriented from top to bottom. Its clarity and consistency in this regard are unmatched by any other language.

Python, on the other hand, has a makeshift implementation of OOP that feels bolted on. For example, there is no true encapsulation in Python: instance variables and methods are “hidden” or made “private” by prefixing their names with underscores. This is extremely kludgy.

Python requires you to explicitly pass “self” as the first argument to all instance methods. This is unbelievably hokey.

Python objects don’t always have the attribute that you expect. For example, the length property is almost always an external function called len().

Functional Programming

Pharo has a lovely implementation of lambdas in its “blocks.” This provides Pharo with a nice functional programming capability. In fact, Pharo’s class library contains many functional constructs.

Python can also do functional programming after a fashion. However, its lambdas are restricted to a single expression, rather than allowing for multiple lines of code. No other programming language in the world has this restriction! I hesitate to call this hokey and kludgy. (Okay, I lied: it’s hokey and kludgy.)

IDE (integrated development environment)

Pharo has a lovely built-in live coding IDE that’s every bit as simple and easy to use as the language itself. Live coding allows you to inspect and modify the code and data in your program while it’s running! This powerful technique practically eliminates the traditional edit-compile-test-debug cycle that has hampered developers for over half a century. This is the main reason why Pharo (Smalltalk) is the most productive general-purpose programming language in the world, according to a study conducted by Namcook Analytics.

Python’s best IDE is PyCharm. While it’s a nice IDE to be sure, there’s no question that it’s much, much larger and more complex than Pharo’s IDE. It would take a long time to master this program.

And PyCharm doesn’t support live coding.

Productivity and Ease of Development

Python has a reputation for being productive. Namcook Analytics tell us that Pharo (Smalltalk) is twice as productive as Python. This is on average. In many cases, Pharo will be much more productive, sometimes by a factor of five!

Plain and simple, Pharo is just much easier to use for programming. The language and its development environment present virtually no cognitive load on the developer.


Python has an enviable ecosystem of libraries. This is a weak point for Pharo. Despite this, Pharo is incredibly versatile. It’s used for many different kinds of applications. For example, Pharo is very good for web development, thanks to the Seaside web framework and the Teapot micro framework.

Pharo is very good for front-end development, thanks to Amber and PharoJS.

Pharo is good for data science, thanks to PolyMath and Roassal.

Pharo is good for virtual reality:

Pharo is good for Internet of Things and embedded programming. See Learn How To Program.

Pharo is used to script the Unreal game engine:

Pharo is being used to fight Ebola!

Pharo is used in wide-scale data visualization for medicines in 16 countries.

Pharo is used for natural language processing.

Pharo is used for machine learning and neural network processing.

Smalltalk, in general, is versatile. The U.S. joint military used Smalltalk to write a million-line battle simulator called JWARS. It actually outperformed a simular program called STORM written in C++ by the U.S. Air Force. Whoa! That’s mind-blowing!

Smalltalk was used by JP Morgan to write their massive financial risk management system called Kapital.

Orient Overseas Container Lines used Smalltalk to develop their IRIS-2 shipping management system.

If Pharo is disadvantaged by its ecosystem, it certainly doesn’t seem to slow it down. In fact, I think it’s fair to say that Pharo is more versatile than Python.


Both Pharo and Python can do multithreading, but Python is hampered by the GIL (global interpreter lock), long a complaint of most programmers.

Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')

How to Remove all Duplicate Files on your Drive via Python

Today you’re going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates.


In many situations you may find yourself having duplicates files on your disk and but when it comes to tracking and checking them manually it can tedious.

Heres a solution

Instead of tracking throughout your disk to see if there is a duplicate, you can automate the process using coding, by writing a program to recursively track through the disk and remove all the found duplicates and that’s what this article is about.

But How do we do it?

If we were to read the whole file and then compare it to the rest of the files recursively through the given directory it will take a very long time, then how do we do it?

The answer is hashing, with hashing can generate a given string of letters and numbers which act as the identity of a given file and if we find any other file with the same identity we gonna delete it.

There’s a variety of hashing algorithms out there such as

  • md5
  • sha1
  • sha224, sha256, sha384 and sha512

How To Compare Tesla and Ford Company By Using Magic Methods in Python

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…

You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.

1. init

class AnyClass:
    def __init__():
        print("Init called on its own")
obj = AnyClass()

The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.

The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.

Init called on its own

2. add

Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,

class AnyClass:
    def __init__(self, var):
        self.some_var = var
    def __add__(self, other_obj):
        print("Calling the add method")
        return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2

Basic Data Types in Python | Python Web Development For Beginners

At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.

Table of Contents  hide

I Mutable objects

II Immutable objects

III Built-in data types in Python

Mutable objects

The Size and declared value and its sequence of the object can able to be modified called mutable objects.

Mutable Data Types are list, dict, set, byte array

Immutable objects

The Size and declared value and its sequence of the object can able to be modified.

Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.

id() and type() is used to know the Identity and data type of the object







Built-in data types in Python

a**=str(“Hello python world”)****#str**














Numbers (int,Float,Complex)

Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.

#signed interger




Python supports 3 types of numeric data.

int (signed integers like 20, 2, 225, etc.)

float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)

complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)

A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).


The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.

# String Handling

‘Hello Python’

#single (') Quoted String

“Hello Python”

# Double (") Quoted String

“”“Hello Python”“”

‘’‘Hello Python’‘’

# triple (‘’') (“”") Quoted String

In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.

The operator “+” is used to concatenate strings and “*” is used to repeat the string.


output**:****‘Hello python’**

"python "*****2

'Output : Python python ’
