New submission from INADA Naoki <songofaca...@gmail.com>:
int() and str.is*** functions accepts other than ASCII.
But we want to accept only ASCII in some cases. (e.g. ipaddress module)
We can use try-except to check ASCII, but it's inefficient.
try:
s.encode('ascii')
except UnicodeEncodeError:
ascii = False
else:
ascii = True
CPython can check string is ASCII efficiently.
