This is a simple Python script to familiarize you with the system module (sys).
Python system module is something cool if you are really interested in python. As of now, I am only showing how you can use stdin, stdout and stderr functions. You can do a lot of cool stuffs using system module. The stdin function can be used to get input data from the python shell. The stdout function is used for outputs and stderr is used to show error messages.
#Import System module import sys print("Enter a number") #input is read using stdin x=int(sys.stdin.readline()) print(x) #output printed using stdout sys.stdout.write('This is stdout text\n') #Error message is shown using stderr sys.stderr.write('This is a stderror\n')
Enter a number 10 10 This is stdout text This is a stderror >>>
