正则表达式与 Python 从行尾匹配

Question

I'm matching the last word 'City' or 'City City'.

Work's on regex101.com ( https://regex101.com/r/7F6Jao/1 ) but not in Python.

folder = i.find ( 'folder' ).text
# Top > Continent > Country > City
    country = re.match ( r'\s+\S*$', folder )
    print ( folder )

Output I get 'None'.

You should be using re.search here, since you don't want your regex pattern to be anchored to the start of the input (which is the default behavior for re.match ):

text = "Top > Continent > Country > City"
p = re.compile("\\b\\S*$")
matches = p.search(text)
if matches:
    print("Found a match: " + matches.group(0))
else:
    print("no match")

This prints:

Found a match: City

EDIT:

Thank you for pointing me in the right direction.

In addition for the scenario (for City names with 2 words):

# Top > Continent > Country > City City 
p = re.compile("[^ ]+\\s+[^ ]+$") 

Output:

City City 
> City 

Seems like cannot exclude the last '>'.

Maybe match from the left capture everything after 3 '>' plus a space?
