List index out of reach

Question

Trying to choose random words from input and output them in a different order but i get this error

import random

inpt = input().split()

for x in range(len(inpt)):
out = ""
wrd = random.randint(0, len(inpt))
out = inpt[wrd] + out
print(out)

Traceback (most recent call last) :
File "..\Playground\", line 8, in <module>
out = inpt[wrd] + out
IndexError: list index out of reach

Answer 1

for x in range(len(inp)-1):
wrd=randint(0,len(inpt)-1)

Answer 2

"random.randint(a, b)" includes b
try random.randrange(0, len(inpt))
or random.randint(0, len(inpt) - 1)

Answer 3

Keys for arrays start from 0. So the last key is the length minus 1. See below.

There are fours words
0 1 2 3
