Random Item from a list

Clearest way to do this is

import random

kids=["Mary","Raj","Jon"]

yourturn=random.choice(kids)

print("It is your turn",yourturn)

#import random library

#Make a list called kids

#make a random choice from kids and put #it into yourturn variable

Or you could create the list inside the yourturn variable

import random

yourturn = random.choice(["John","Mary","Sheila","Mark"])

print("It is your turn",yourturn)

This could output as

>>>

It is your turn Mary

>>>

Mary could be replaced by John, Sheila or Mark

Random item from a file

Make sure the file you have created is in the same folder as the Python program you are writing.

Make sure each object is on a separate line.

Save the file as a .txt file.

In this example the file is films.txt

This would output as a random film from the file

Note you must open and close the text file

You can download this file as files.py and the films.txt below (You must place them in the same folder)
