The walrus operator hardly changes that example at all:
if m := re.match(pattern1, line):
do_stuff(m.group(1))
else:
if m := re.match(pattern2, line):
do_other_stuff(m.group(2))
else:
if m := re.match(pattern3, line):
do_things(m.groups())
else:
m = ...
The walrus operator allows you to use `elif` there to avoid cascading indentation.
if m := re.match(pattern1, line):
do_stuff(m.group(1))
elif m := re.match(pattern2, line):
do_other_stuff(m.group(2))
elif m := re.match(pattern3, line):
do_things(m.groups())
else:
...
Python is extremely suitable for these kind of problems. C++ is also often used, especially by competitive programmers.
