Hello all,
I have another homework problem.
I have a textfile. It contains lines of string.
I am required to only print out a certain part of the string.
For example the textfile contain:
ABC X N
BCD Q E
ABC W A
I need to print all the parts that come after only ABC.

As with lots of things in python, there are lots of ways of approaching this,
here are some hints for you to think about (in no particular order):
- REGEX
- replace()
- string[:y]
- split()
And of course, you could consider creating a table with every possible string

any new features, and only bug fixes will ever be made.
