PIp is python’s most widely used package manager. Installed by default for versions of python. It is similar to the node’s npm, ruby on rails gem if anyone has ever used it.
pip install somepackage
pip install SomePackage==1.x.x
pip install SomePackage>=1.0.4
pip install -r requirements.txt
pip freeze > requirements.txt
pip freeze --local > requirements.txt
pipTo list all installed packages (already exists in the requirements.txt file or not):
pip list --outdated
pip install --upgrade SomePackage
pipour version is not the latest version.
pip install --upgrade pip
pipto the latest current version (It looks like it is currently 19.0.3). We can see the version of
pip -V pip --version
pip uninstall SomePackage
pip install [package]
pip2 install [package]
pip3 install [package]
pip install [package]

What is Pyenv?
Pyenv is a fantastic tool for installing and managing multiple Python versions. It enables a developer to quickly gain access to newer versions of Python and keeps the system clean and free of unnecessary package bloat. It also offers the ability to quickly switch from one version of Python to another, as well as specify the version of Python a given project uses and can automatically switch to that version. This tutorial covers how to install pyenv on Ubuntu 18.04.

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
Welcome to my blog, In this article, we will learn the top 20 most useful python modules or packages and these modules every Python developer should know.
Hello everybody and welcome back so in this article I’m going to be sharing with you 20 Python modules you need to know. Now I’ve split these python modules into four different categories to make little bit easier for us and the categories are:
Near the end of the article, I also share my personal favorite Python module so make sure you stay tuned to see what that is also make sure to share with me in the comments down below your favorite Python module.

The Python Package Index (PyPI) is a repository of python packages contributed by open-source python community to help others. What’s the purpose of creating packages? Without them, we would have to rely on sharing the code by copy/paste which is not efficient. A package can have pieces of code that grab data from an API, do some manipulations on inputs etc. Let’s see an example of python package I created to convert text to braille and steps to publish to PyPI.
Create a folder structure in the format shown below. The main package folder name should be same as your package name. The folder that contains your code can be named anything. Here I have kept the name same as the main package folder.
. └── pybraille (main package folder) └── pybraille (folder that contains your code) └── your code here
Place all the class or script files in the folder that contains your code and add a init.py file. The init.py file should contain the import statements to expose only the required classes and functions you want the user to access.
from pybraille.main import convertText, convertFile
**Also, you can add a list named all in the init.py file containing the module names. This allows the user to import all the module names mentioned in all variable when **
from package import * is encountered.
__all__ = [‘convertText’, ‘convertFile’]
