11 Tips And Tricks To Write Better Python Code

In this video, I show 11 Tips and Tricks to Write Better Python code! I show a lot of best practices that improve your code by making your code much cleaner and more Pythonic.

All Tips:

  1. Iterate with enumerate instead or range(len(x))
  2. Use list comprehension instead of raw for loops
  3. Sort complex iterables with sorted()
  4. Store unique values with Sets
  5. Save memory with Generators
  6. Define default values in Dictionaries with .get() and .setdefault()
  7. Count hashable objects with collections.Counter
  8. Format strings with f-Strings (Python 3.6+)
  9. Concatenate strings with .join()
  10. Merge dictionaries with {**d1, **d2} (Python 3.5+)
  11. Simplify if-statements with if x in list

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

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')

Common Anti-Patterns in Python

Improve and streamline your code by learning about these common anti-patterns that will save you time and effort. Examples of good and bad practices included.

1. Not Using with to Open Files

When you open a file without the with statement, you need to remember closing the file via calling close() explicitly when finished with processing it. Even while explicitly closing the resource, there are chances of exceptions before the resource is actually released. This can cause inconsistencies, or lead the file to be corrupted. Opening a file via with implements the context manager protocol that releases the resource when execution is outside of the with block.

2. Using list/dict/set Comprehension Unnecessarily

3. Unnecessary Use of Generators

4. Returning More Than One Object Type in a Function Call

5. Not Using get() to Return Default Values From a Dictionary

Using Black To Auto Format Your Python

Writing python code is one thing and writing the code in a good format is another thing. Most of the time especially junior coders/programmers focus on making sure the codes are working and forget to format their codes.

If you write a small program (with 1000 lines of codes) you could get away without formatting your code, but as programs get more and more complex, they get harder and harder to understand and at some point (around 15,000 lines of code), it becomes harder to understand the code that you yourself wrote.

The difference between working on well-formatted code and working on badly formatted code is like the difference between living in a palace and living in a dirty house.

Why formatting your python code is important?
