save all possible random strings in python

Question

Here is my code:

def randomword(length):
    allchar = string.ascii_lowercase
    keywords =[''.join(random.choice(allchar) for i in range(length))]
    return keywords

print(randomword(4))

I didn't get all possible random string with 4 characters.I only get one possible random string,such as ['uuph'].

You're returning around `23751` items. Does that sound right? — cs95, Mar 28 '18 at 23:47
@cᴏʟᴅsᴘᴇᴇᴅ yes.so how can I save all 23751 items? — Rya, Mar 28 '18 at 23:49
If by "save" you mean save to a file on your filesystem disk, you can `with open("yourfile", 'w') as f: f.write(keywords)` — JacobIRR, Mar 28 '18 at 23:52
@IgnacioVazquez-Abrams it means print out all possible random strings with 4 chars. — Rya, Mar 28 '18 at 23:52
"all possible" and "random" comprise a contradiction in terms: if you're generating all possible permutations, the result is *not* random. — Prune, Mar 29 '18 at 00:26

It sounds like what you really want is all the possible permutations of length N from a superset.

Check out the itertools.permutations() method.

Or the combination with replacement mentioned above.
