2. regex_choice.py - submit one program for Option 1, 2 or 3 below
Functions and exception handling are encouraged, but not required.
Use regex, and provide user-friendly prompts, informational output & comments.
Option 1:
Enter a source text to be searched, such as a favorite
Option 2:
We want user input like -12.34 to be recognized as a 001
number! Write a program using regex that can identify
input of numerals that may or may not have a minus
sign (-) in the first position, and may or may not have
one decimal (.). It's the long-awaited float validation!
poem or song lyric. Save it into a single string variable, like
120 130
this:
my_song = ("Always look on the light side of life.
If life seems jolly rotten,
There\'s something you\'ve forgotten
And that\'s to laugh and smile and dance and sing.")
Using regex, write 10 different expressions to find
characters, words, phrases or patterns - all searching in
this same source text (my_song).
You can choose what you are looking for. Make it
interesting, & preceed each with a comment to explain.
Option 3:
Write your own regex that would be useful in real life.
Don't just lift a typical one from online! Provide
comments to show how your regex works & what it
does.
