How to bring all lines in a bunch of text into one line in Python

counter=0
text=raw_input("text:")
for char in text:
    if char==" ":
         counter+=1
return counter

This code works for one line of code, but doesn't if text is more than one line (this happens of course because raw_input only collects one line of code(I think)). Is there any way I can get input from the user and--even if there is more than one line--return the number of words? Thanks!
