Modules​

What are modules?

A module is a file containing Python definitions and statements. Modules can define functions, classes, and variables that you can reference in other Python .py files or via the Python command line interpreter.

In Python, modules are accessed by using the import statement. When you do this, you execute the code of the module, keeping the scopes of the definitions so that your current file(s) can make use of these.

Picture

Random module - random integer

Look at the following code, then run it to see the out out. Now run it again

​Random module - random float

Look at the following code, then run it to see the out out. Now run it again

​Random module - random.random

Look at the following code, then run it to see the out out. Now run it again

​Random module - random value from a list or 1D array

Look at the following code, then run it to see the out out. Now run it again

Python challenge - Random module

​Enter the following code in a Python code editor. Before running the code, what do you think it will do? Press "F5" then "Enter" to runn
Picture
In this example the module called "random" is imported. random.randint generates a random integar. Change the 6 to a higher number and test the code.

Challenges using random...

See if you can code the following programs:
  1. A dice program
  2. Play against the computer at "Rock, paper, scissors" (maybe it keeps score)
  3. A magic 8-ball
  4. The human guesses the random computer generated number
  5. Random joke generator
  6. ​Football score prediction
  7. Astrology/Horoscope predictions
