Remove periods at the end of sentences in python

Question

I have sentences like this - \"this is a test. 4.55 and 5,000.\" I want to remove the period at the end of the sentences, but not between numbers. My output has to be - \"this

Answer 1

How about

pattern = re.compile(r'\.(\s)')
wordList = pattern.sub(r'\1', wordList)

This replaces a period followed by a space with just the space.

Answer 2

Try a negative lookahead:

\.(?!\d)

What this matches is any period that's not followed by a digit.

Answer 3

In regex, the $ special character "[matches] the end of the string or just before the newline at the end of the string"

In that case, assuming only one sentence per line, I would suggest the following:

\.$

This will match only periods that occur at the end of a string (or end of a line for multiline strings). Of course, if you cannot guarantee one sentence per line then they isn't the solution for you.
