How to prompt for user input and read command-line arguments [closed]


To read user input you can try the cmd module for easily creating a mini-command line interpreter (with help texts and autocompletion) and raw_input (input for Python 3+) for reading a line of text from the user.

text = raw_input("prompt")  # Python 2text = input("prompt")  # Python 3

Command line inputs are in sys.argv. Try this in your script:

import sysprint (sys.argv)

There are two modules for parsing command line options: optparse (deprecated since Python 2.7, use argparse instead) and getopt. If you just want to input files to your script, behold the power of fileinput.

The Python library reference is your friend.


var = raw_input("Please enter something: ")print "you entered", var

Or for Python 3:

var = input("Please enter something: ")print("You entered: " + var)


raw_input is no longer available in Python 3.x. But raw_input was renamed input, so the same functionality exists.

input_var = input("Enter something: ")print ("you entered " + input_var)
