Range copy not getting complete range

Question

1.00/5 (1 vote)

So I have this program:

#first is the first number, c is the constant it increments by, and l is the last number

Python

def seqlist(first,c,l):
    L = []
    while first < l:
        L.append(first)
        first+=c
        continue
    return L

(The above code is indented in the actual program)

But it doesn't return the complete range. I have tried using the actual range function, but it returns the same thing. What am I doing wrong?

What makes you thinking anything is wrong?

that it doesn't return the complete range when tested. Even the normal range() method doesn't return the whole range

It does return correct range, exactly as you defined it. I even checked it up on Python interpreter, just in case; all works correctly. This is not that your code is wrong; from your words, it sounds like your expectations are wrong.

Note two things: 1) you are using while loop, which means that the check is done before each iteration, not after; the meaning corresponds to the common-sense English meaning of this word; 2) you use the operator '<', not '<='; so, if you expect, in some cases, l to be in range, it cannot happen.
