WHY YOU SHOULD LEARN USING PYTHON ON CMD?

You can use Python on CMD (Command prompt in windows). Python on CMD works just like it would work in reality. What I mean to say is, when you are using programs like Sublime Text 3 (which I use), you can run the code using the shortcut ’CTRL+B’ in sublime text itself. But the drawback to this is that it can only be used to print something.

 For example, if your program is meant to take input from the user to continue (which I will teach you soon, SO STAY TUNED!!!!). Using sublime text you can only print the statements from the code you cannot actually take the input from the user.


So basically, you can only check if your code is working without any error using sublime text. But using cmd you can actually check how your code will work in real life. It will take input from the user, print the statement and execute the code as it is meant to.

So learning to run Python using cmd is highly recommended.

Not only this, eventually you have to learn to use Python through cmd because as you get advanced you will be using different packages and module which do not come pre-installed in Python, you have to install it separately, and that can be done using cmd.

 

HOW TO USE PYTHON ON CMD?

There are two method which you can use to run Python using cmd, but first go the folder where you have installed Python (if you haven’t installed Python yet, you can install it here ) and copy the filepath from the bar on the top.

 

 

Method #1:

1.     Press ‘+R’ on the keyboard and type ‘cmd’ in the dialog box that opens and press Enter.

 

 

2.     When cmd opens, type ‘set path’ and paste the filepath you copied and press Enter

 

 

The drawback of using this method is that it is temporary. When you close cmd, the path will be lost.

To make it permanent you can use the next method.

Method #2:

1.     Go to ‘My Computer’

2.     Right-click anywhere on the window

 

3.     Click on ‘Properties’ form the drop-down menu

4.     Click on ‘advanced system setting’

 

 

5.     Go to ‘environment variables’

 

6.      Double-click on ‘Path’ and paste the filepath you copied before at the end of the ‘variable value’ section

7.     Now go back to the folder where you have installed Python and copy the filepath of the ‘Scripts’ folder in the python folder

 

 

8.     Then add a semi-colon (;) at the end of the  ‘variable value’ section in the ‘path’ window and paste the filepath of the scripts folder

 

 

9.     Now you all you have to do to run Python is type ‘python’ in cmd and press Enter and Python will be loaded.
