Homogenization of scientific computing – Python is eating other languages’ lunch

My solution:

    lines = [line for line in open("bible.txt")]
    words = [word for line in lines for word in line.split()]
    counts = {word:0 for word in words}
    for word in words:
        counts[word] += 1

No imports needed. Linear time. A bit inefficient in the dictionary comprehension, but easy to read.

The "lines=" and "words=" can be compressed into one line, but I figure this is a bit easier to read for people who aren't familiar with nested list comprehensions.

I'm not too familiar with Python, but this is case sensitive unlike benhoyt's examples. Would this be case insensitive?

    lines = [line for line in open("bible.txt")]
    words = [word.lower() for line in lines for word in line.split()]
    counts = {word:0 for word in words}
    for word in words:
        counts[word] += 1

If you allow one import to sneak in, I think a `defaultdict` would do nicely. :-)
