python multiple user input in single line

I have to read a few user input parameters. Now I could do that for every single in a line e.g. parameter1=raw_input("Parameter 1:") parameter2=raw_input("Parameter 2:")

For better test purpose, it's more practical to do that in one line. For example: Input(parameters) could be: 1 both 0.5 2 5 0.8

So, is it possible to make 6 Parameters (some are int, some string and some float) out of this line?

B.t.w. I'm using python 2.7

Thanks for your help!

Had the question been in Python 3, here is the solution. Can't say if it will work in Python 2

What we do is make a list of the input and have it split on spaces. Then all we have to do is use the list

l=input().split(' ')

If instead of space, the separators were ',' we do the following and so on:

l=input().split(',')

Just split the contents by whitespace:

data = [int(i) for i in raw_input().split()] # cast to integers

Or you can alternatively use Python re:

data = [int(i) for i in re.findall(r'\d+', raw_input())]

use regex for this case

import re

re_exp = re.compile(r'\s*(\d+)\s*([^\d\s])+\s*(\d+)')
expr = raw_input()
match = re_exp.match(expr)
if match:
    num1, oper, num2 = match.groups()
    print num1, oper, num2

It takes 3 inputs in one line (INT,OPERATION,INT). And prints it for you (int,operation,int) Work around it, to your need.

IDLE Output:

4 + 4 ( Three inputs)

4 + 4 (Prints them)

You can do as follow:

separator = ' '
parameters = raw_input("parameters:").split(separator)

parameters will contain the list of the parameters given by the user.

separator is the separator you want to use (a space in your example, but it could be any string)
