Why the regex to match a project tag is not working?

Question

Can anyone provide guidance on why the following regex is not working?

project = 'AirPortFamily'
line = 'AirPortFamily-1425.9:'
if re.findall('%s-(\d+):'%project,line):
    print line

EXPECTED OUTPUT:-

AirPortFamily-1425.9

Answer 1

You should match the optional groups of digits preceded by a dot:

if re.findall(r'(%s-\d+(?:\.\d+)*):'%project,line):
