python creating a list from lines in a file

Question

I need to create a list of strings for each line in a file.

Example:

This is my file.
These are examples.

would create: ['This', 'is', 'my', 'file'] ['These', 'are', 'examples']

I need to do this because I am trying to translate a file into a pig latin file.

What have you tried? Even if your attempt is just reading lines from the file, that's a great place to start. — mgilson

I literally just have inputFile= open(fileName, 'r') and I really don't have an idea where to go from there. — tinydancer9454

Well, any answer is going to involve iterating over lines in a file. Why not do a search to figure out how to get the lines? After you've gotten the lines, then you can start working on how to transform them into the lists you want. — mgilson

Split each line in the file along the space character and retrieve it as a list.

f = open('filename.txt', 'r')
li = [line.split() for line in f]

Try this:

res = []
with open(filename, 'r') as f:
    for line in f:
         res.append(line.split())

OR:

map(str.split, open(filename, 'r'))

If you need to get rid of dots:

res = []
with open(filename, 'r') as f:
    for line in f:
         res.append(line.strip('.').split())

You can also use the readLines

f = open('file.txt', 'r')
lines = [line.split(' ') for line in f.readlines()]
