Unused variable 'lineno'
101 if mimetypes.guess_type(filepath)[0] is None:
102 continue
103 with open(filepath) as handle:
104 for lineno, line in enumerate(handle):105 mo = matcher.search(line)
106 if mo:
107 found.append(mo.group())
Description
An unused variable takes up space in the code, and can lead to confusion, and it should be removed. If this variable is necessary, name the variable _ to indicate that it will be unused, or start the name with unused or _unused.
Bad practice
def update():
for i in range(10): # Usused variable `i`
time.sleep(0.01)
display_result()
Preferred:
def update():
for _ in range(10):
time.sleep(0.01)
display_result()
