I get a IndexError: list index out of range Error

I´m having some troubles on my code, that implements a function that verifies the lenght of a string and return that string with or without spaces.

If String b >= 15 return b

If strinf < 15 return “number os spaces until len(b)2 + string b

But I get a IndexError: list index out of range Error. I cannot figure out where or why.

Traceback:

============= RESTART: C:UserspboDesktopTrab_04.py =============

ascii_letters = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ Traceback (most recent call last):

File “C:UserspboDesktopTrab_04.py”, line 30, in o2.append(a(o1[e]))

IndexError: list index out of range

============= ============= ============= ============= =============

Thanks a lot for any possible help.

Answer

It looks like your indentation is incorrect (see also What is Python Whitespace and how does it work?).

If you change the following:

o1 = []
for e in range(9622):
    k = randint(1, 25)
    s = ""
for l in range(k):
    s = s + choice(ascii_letters)
o1.append(s)

to:

o1 = []
for e in range(9622):
    k = randint(1, 25)
    s = ""
    for l in range(k):
        s = s + choice(ascii_letters)
        o1.append(s)

Then, your code appears to work.
