Python and User input

How do I have a Python script that can accept user input (assuming this is possible) and how do I make it read in arguments if run from the command line?

From stackoverflow Teifion

• var = raw_input("Enter something: ")
  print "you entered ", var
  

  From Luca

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

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

  From Dave Webb

• To read user input you can try the cmd module for fancy stuff and raw_input for less fancy stuff.

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

  import sys
  print sys.argv
  

  There are two modules for parsing command line options: optparse and getopt. If you just want to input files to your script, behold the power of fileinput.

  The Python library reference is your friend.

  From Antti Rasinen

• 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.

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

  From Vhaerun

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