You're right. There's no written statement. The exercise was suggested
by the teacher while in class. It was something like ``write a program
that copies text files by getting source and destination via the
command-line.''
Well then, I'd think about using "shutil", e.g., "shutil.copy".
Check it out in "The Python Library Reference"; it's 11.10.1 in
release 3.13.0a0.
It sounds like the main point of the exercise may have been to use
command line arguments. The Original Post tried to do this in a
complicated and clumsy (non-Pythonic) way.
Easier and more Pythonic would be to delete the def main() block and then:
if __name__ == '__main__':
import sys # could import this at start of file
if len(sys.argv) == 3:
copy(sys.argv[1], sys.argv[2])
else:
print(usage(sys.argv[0]))
or perhaps easier to read:
if __name__ == '__main__':
import sys # could import this at start of file
try:
prog, src, dest = sys.argv
except:
print(usage(sys.argv[0]))
sys.exit(1) # or some other error code
copy(src, dest)
But, yeah, if the Python community doesn't do that, it's all what you
say.
Community or no community, in Python, you can have:
def f( s, S ):
return 2*s+S
. Should the docs then say, "returns 2*S+S"?
PS. Is it just me or there's just us in this used-to-be-very-active
group? Thanks for being my teacher here. Have a good day!
Thanks, you too!
On one hand, many people seem to prefer websites for discussions
nowadays. On the other hand, if I had not responded, probably
someone else would have.
