I am a newbie of python, How to print some words input by user ?

Question

My code as follow:

#!/usr/bin/python
#Filename:2_7.py
text=raw_input("Enter string:")
for ?? in range(??)
    print 

the ?? means I don't know how to write, could you please tell me if you know, thanks

Answer 1

Do you want to split the string into separate words and print each one?

e.g.

for word in text.split():
    print word

in action:

Enter string: here are some words
here
are
some
words

Answer 2

Maybe you want something like this?

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

Answer 3

Well, for a simplistic case, you could try:

for word in text.split(" "):
    print word

For a more complex case where you want to use a regular expression for a splitter:

for word in re.split("\W+", text):
    if word != "":
        print word

The earlier example will output "Hello, my name is Pax." as:

Hello,
my
name
is
Pax.

while the latter will more correctly give you:

Hello
my
name
is
Pax

(and you can improve the regex if you have more edge cases).
