While trying to learn a little more about regular expressions, a tutorial suggested that you can use the b to match a word boundary. However, the following snippet in the Python interpreter does not work as expected:
Suppose this string:
I have a number of strings similar to Current Level: 13.4 db. and I would like to extract just the floating point number. I say floating and not decimal as it’s sometimes whole.

I am trying to use a regular expression to extract words inside of a pattern.
I need to create a Pandas DataFrame based on a text file based on the following structure:
Is there any benefit in using compile for regular expressions in Python?
I am looking to see whether a word occurs in a sentence using regex. Words are separated by spaces, but may have punctuation on either side. If the word is in the middle of the string, the following match works (it prevents part-words from matching, allows punctuation on either side of the word).
