If you need a variable number of loops, put the loops themselves in a
loop, which you go through the required number of times. In your case
I would do:
def allwrds(alphabet,n):
result = [""] # for n=0, we have a single empty string
for _ in range(n):
result = [w+letter for letter in alphabet for w in result]
return result
Or, in case you are not comfortable with list comprehension (or want
easy translation to a language without such a powerful tool):
def allwrds(alphabet,n):
result = [""] # for n=0, we have a single empty string
for _ in range(n):
tempwrds = []
for w in result:
for letter in alphabet:
tempwrds.append(w+letter)
result = tempwrds
return result
