'Conditions' was the subject of the module 4. Here's different examples of how you use them.

conditions.py

# you can create a list like this
fruits = [
    'apple',
    'grapes',
    'banana'
]

favourite_fruit = "mango"

if favourite_fruit in fruits:
    print(f"My favourite fruit {favourite_fruit} is on the list of fruits!")
else:
    print(f"My favourite fruit {favourite_fruit} is missing!")


# create a Dictionary
# dictionary may include other dictionaries, lists and be very complex
person = {
    'first_name': 'Alex',
    'last_name': 'Zverev',
    'age': 23,
    'male': True  # this is a boolean value: it can be either True or False
}

# access specific attributes of the Dictionary
print("Name: " + person['first_name'])

# this is how you inject
if person['male']:
    print(f"{person['first_name']} is a man")
else:
    print(f"{person['first_name']} is a woman")


# multiple conditions
if person['age'] <= 1:
    print(f"{person['first_name']} is a baby")
elif 1 < person['age'] <= 3:
    print(f"{person['first_name']} is a toddler")
elif 3 < person['age'] <= 5:
    print(f"{person['first_name']} is at preschool stage")
elif 5 < person['age'] <= 12:
    print(f"{person['first_name']} is a gradeschooler")
elif 12 < person['age'] <= 18:
    print(f"{person['first_name']} is a teenager")
elif 18 < person['age'] <= 25:
    print(f"{person['first_name']} is a young adult")
elif 25 < person['age'] <= 65:
    print(f"{person['first_name']} is an adult")
elif 65 < person['age']:
    print(f"{person['first_name']} is a senior")
else:
    print("This will never be printed :p")
