weird error in random sentence generator

[bobger]

i put all the lists on top and the error still occurs.I am using python3.6.3 on windows 10.
sometimes i get this error sometimes not when i run this code over and over.

Error:
Traceback (most recent call last):
  File "C:\Users\barbara\AppData\Local\Programs\Python\Python36-32\if_ranner.py", line 39, in <module>
    print (people[morn] + ' ' + actions[morn] + ' ' + thesethings[morn] + ' ' + timely[morn])
IndexError: tuple index out of range

here is my python code

import random

print ("returns random element from list [10, 20, 30, 40, 50]) : ", random.choice([10, 20, 30, 40, 50]))
print ("returns random character from string 'Hello World' : ", random.choice('Hello World'))
b = ["sam went to the store", "bob visited jill", "billy went hunting"] 
print(random.choice(b))
