In this tutorial you will learn How to run Python Programs (.py files ) on windows 10 computer.We can use Python command prompt and idle interactive interfa. To run code: use shortcut Ctrl+Alt+N. Or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in editor context menu. Or click Run Code button in editor title menu. Or click Run Code button in context menu of file explorer. To stop the running code.
Open a File on the Server
Assume we have the following file, located in the same folder as Python:
demofile.txt
This file is for testing purposes.
Good Luck!
Python Call Python File
To open the file, use the built-in open() function.
The open() function returns a file object, which has a read() method for reading the content of the file:
Example
Run Example »If the file is located in a different location, you will have to specify the file path, like this:
Example
Open a file on a different location:
print(f.read())
Run Example »Read Only Parts of the File
By default the read() method returns the whole text, but you can also specify how many characters you want to return:
Example
Return the 5 first characters of the file:
Run Example »Read Lines
You can return one line by using the readline() method:

Example
Read one line of the file:
Run Example »By calling readline() two times, you can read the two first lines:
Example
Read two lines of the file:
print(f.readline())
print(f.readline())
Run Example »By looping through the lines of the file, you can read the whole file, line by line:
Example
Loop through the file line by line:
for x in f:
print(x)
Close Files
It is a good practice to always close the file when you are done with it.
Example
Close the file when you are finish with it:
print(f.readline())
f.close()
