Hi everyone,
Maybe these questions will sound strange to you, but I sometime have a
hard time switching from Java to Python ;-)
Let's say I have a function like this :
def show_lines(file):
for next_line in file:
...
What can I do to be sure that the input argument is indeed a 'File'
object ?
#1 : should I start by checking that 'file' is indeed an instance of a
File object ? (and how do I do this ?)
#2 : should I do nothing ? (but I don't like the idea of risking to
have a runtime exception raised somewhere)
Thanks for helping...
