Here's an alternate way....

fd_in = open('myfiles/test_text.txt', 'r')
each_line = ''
a_list = []

for line in fd_in.readlines():
    for word in line.split():
        each_line += word + ','
        a_list.append(word)        # If a real list is desired
    print each_line                    # Keep the trailing comma
    print each_line.rstrip(',')       # Delete the trailing comma
    each_line = ''                      # Ready for the next line

    #a_list = []                          # Clear the list if one line per
                                              # list is desired

print a_list                              # Otherwise the whole file is
                                              # contained in the list

fd_in.close()


Prints:

This,is,line,one,
This,is,line,one
This,is,line,two,
This,is,line,two
This,is,line,three,
This,is,line,three
This,is,line,four,
This,is,line,four
This,is,line,five,
This,is,line,five
This,is,line,six,
This,is,line,six

['This', 'is', 'line', 'one', 'This', 'is', 'line', 'two', 'This', 'is',...]

Several concepts are embedded, if that's a confusion, I apologize.
Of course, you can write to an output file in lieu of the prints.
