Lets say I have a function:

from time import sleep

def doSomethingThatTakesALongTime(number):
  print number
  sleep(10)

and then I call it in a for loop

for number in range(10):
  doSomethingThatTakesALongTime(number)

How can I set this up so that it only takes 10 seconds TOTAL to print out:

$ 0123456789

Instead of taking 100 seconds. If it helps, I’m going to use the information YOU provide to do asynchronous web scraping. i.e. I have a list of sites I want to visit, but I want to visit them simultaneously, rather than wait for each one to complete.
