如何在空格分隔字符串？

Question

I want to split string where the spaces are, and put it into an array. For example, if the str is "foo bar asdf" I want the array to be ["foo", "bar", "asdf"]. I know you can easily do that like so:

str = raw_input("Enter String")

cstr = ""
for char in str:
    if char == " ":
        print cstr
    else:
        cstr = cstr + char

But that outputs only the first word until the space, and it is quite bulky for something so simple. How can I do this simply?

Answer 1

This is what the split method on strings is for:

>>> "foo bar asdf".split(' ')
['foo', 'bar', 'asdf']

The argument is the string to split on, or you can just do .split() without an argument to split on any whitespace.

Answer 2

I think you're looking for: http://docs.python.org/library/stdtypes.html?highlight=split#str.split

Usage in your case would be something like:

 for cstr in mystr.split(' '):  #renamed 'str' to 'mystr'
     print cstr
