Obtain the system platform Name:

Import sys
Print (sys. platform)

 

Stream redirection: Export python output data to other files: python ***. py> test.txt

 

To avoid program flash on windows, add: input () at the end of the Code ()

 

Python3.x to simulate the input (evaluate the string) in python2.x, use eval (input ())

 

If you want python to run the file again in the same session (do not stop or restart the Session), you need to call the reload function in the imp standard library module (2. x is built-in, 3. x is not built-in)

From imp import reload

Reload (***)
