Is this text processing code Pythonic?

Question

I need to take a line of text (words) and split it in half at the first space following the midpoint of the line; e.g.:

The quick brown fox jumps over the lazy dog.
                         ^

The mid-point of the line above is at position 22, and the line is split at the space following the word "jumps".

I would appreciate if you could look at the following code and tell me if it is Pythonic. If not, please suggest the correct way. Thank you. (PS: I come from a C++ background.)

    midLine = len(line) / 2                  # Locate mid-point of line.
    foundSpace = False
    # Traverse the second half of the line and look for a space.
    for ii in range(midLine):
        if line[midLine + ii] == ' ':        # Found a space.
            foundSpace = True
            break
    if (foundSpace == True):
        linePart1 = line[:midLine + ii]      # Start of line to location of space - 1.
        linePart2 = line[midLine + ii + 1:]  # Location of space + 1 to end of line.

Answer 1

Pythonic is to use builtin functions where available. string.index does the job here.

def half(s):
    idx = s.index(' ', len(s) / 2)
    return s[:idx], s[idx+1:]

This will raise a ValueError if there's no suitable place to break the string. You may have to adjust the code if that's not what you want.
