How to use pip for Python 3 alongside Python 2?

pip is a package management system used to install and manage software packages written in Python.You can find many third party packages on Python Package Index(PyPI). There are currently 94060 packages here.You can browse all of the packages at the following link

PyPI packages

So to use pip for Python 3 alongside Python 2, Follow this steps:

Step 1:

First of all, you have to install both python versions.If you haven't installed it already you can see my other post how to install python 2 and python 3 on Windows PC.

Make sure to check Add python 3.5 to path while installing Python 3.

Step 2:

After installation, you have to setup your path for pip (for Python 2) in your windows PC. To do that first of all copy the following path

C:\Python27\Scripts

Make sure this path matches your Windows' Python 2 path.So please crosscheck before applying this.Otherwise, this method won't work.

Step 3:

Go to Control Panel\System and Security\System
Go to Advanced System Settings,
Click on Environment Variables
Double click on Path
Click on New
Add the path of which is provided in Step 2.

Congratulations! Now you can use pip for both versions of python separately:

To use pip for Python 2 just type pip2 in command prompt

To use pip for Python 3 just type pip3 in command prompt

So if you use pip3, pip will install all the packages only for Python 3. It will have not any effect on Python 2. So as you expect, pip2 will only install for Python 2.

Hope this helps :)

Python 2 vs Python 3 Pystone benchmarking test!

When Python 3 came out, It was slower than Python 2. As Python's official blog says Python 3 is 10% slower than Python 2. So it means Python 2 is faster than python 3 by some margin. In this Benchmarking, we will use Pystone benchmarks to compare Python 2 and Python 3. My system specification is listed below: CPU = Intel core i3 2100 @ 3.10 GHZ GPU = Nvidia Geforce 210 RAM = 2 GB OS = Windows 10 Pro The benchmarking results may vary upon your system specification. Here's the result. python 3 pystone benchmarks python 2 pystone benchmarks As you can see python 2 has 24% higher benchmarks than python 3 which is pretty impressive. Maybe this is one of the reasons that some programmers prefers to use Python 2 instead of Python 3. Hope this helps :)

A Typical Guide to Exceptions in Python

In this blog, I will give you the basic but important information regarding the Exceptions in Python. As we all know, we always get some Errors and Exceptions in program every now and then, so to know what that exception is all about. We should know all about exception. So, let's dive into it. First of all, let's understand what Exception is? If a statement or expression is syntactically correct, it may cause an error when an attempt is made to execute it. This errors detected during execution are called Exceptions. Example:- Exceptions are of different types and this error message indicates what happened. Like you see here in example i.e. ZeroDivisionError, NameError, TypeError. These are basic errors in the program. List of Standard Exception :- Exception - Base Class for all the exception Stop Iteration - Raised when the next() method of an iterator does not point to any object. Example :- System Exit - Raised by the sys.exit...
