Project

Randomisation

Import the module

import random

# numbers between 0 and 1 but 1 is exculded
print(random.random())

x = random.randrange(0, 10)
print(f"The random value is: {x}")

Heads or Tails

import random

random_side = random.randint(0, 1)
if random_side == 1:
    print("Heads")
else:
    print("Tails")

Nested list

fruits = ["strawberry", "apple", "orange"]
vegetables = ["spinach", "tomato", "kale"]

nested_list = [fruits, vegetables]

Some tips

Functions and global variables

Global variables

# global variable
x = 'amazing'

def amazing_func():
    print(f"The world is {x} !")

amazing_func() #Expected outout The world is amazing

Global variables and function local variable

# global and local variables with same name
my_var = 'awesome'

def awesome_func():
    # local variable
    my_var = 'REALLY awesome'
    print(f"The world is {my_var}")

awesome_func() # The world is REALLY awesome

print(f"The other world is {my_var} !") # The other world is awesome

Define a global variable inside a function

def global_func():
    global the_var
    the_var = 'Coraline'

global_func() #call the function for using the global variable

print(f"It's {the_var} ! Not Caroline at all.") # Output: It's Coraline ! Not Caroline at all.

Create a module

Create a main file called main.py
Create another file called new_module
Inside new_module, create a variable or function
To use your new module, just import the file name

new_module.py

pi = 3.14159246

def say_hello():
    print("Oh hello!")

main.py

import new_module

print(new_module.pi)
# Say hello form new module
new_module.say_hello()

What you'll learn

Create a module, working with nested list, create functions and scope of variables.
