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

Answer 1

As of Python 3.2 2.7, there is now argparse for processing command line arguments.

Answer 2

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

Or for Python 3:

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

Answer 3

Use 'raw_input' for input from a console/terminal.

if you just want a command line argument like a file name or something e.g.

$ python my_prog.py file_name.txt

then you can use sys.argv...

import sys
print sys.argv

sys.argv is a list where 0 is the program name, so in the above example sys.argv[1] would be "file_name.txt"

If you want to have full on command line options use the optparse module.

Answer 4

Careful not to use the input function, unless you know what you're doing. Unlike raw_input, input will accept any python expression, so it's kinda like eval

Answer 5

The best way to process command line arguments is the argparse module.

Use raw_input() to get user input. If you import the readline module your users will have line editing and history.

Answer 6

import six

if six.PY2:
    input = raw_input

print(input("What's your name? "))
