Conditionals let you make decisions in your code.

if else

choice = input("Cat or Dog?")

if choice == 'dog':
  print("Good choice")
else:
  print("Become a dog person")

Nested if else

choice = input("Cat or Dog?")

if choice == 'dog':
  print("Good choice")
  owner = input("Do you own a dog?")
  if owner == 'yes':
    print("Good. Get another")
  else:
    print("What are you waiting for?")
else:
  print("Become a dog person")

if elif else

If you have more than one condition to check against use elif.

choice = input("Cat or Dog?")

if choice == 'cat'
  print("Become a dog person")
elif choice == 'dog':
  print("Good choice")
else:
  print("I'm sorry... what?")

Comparison operators

In our conditionals, comparison operators help us to compare more than one value, or have more than one condition.

Modulo

The modulo operator % return the remainder of a division. So basically

10 = 3+3+3+1

10%3 = 1

However in programming I have learnt over time and a lot of digging that this operator is a bit more powerful than it seems to be. Basically the operator can help you set upper bounds.

Example: x%5

For any value of 'x' our result will be a number from this given list [1, 2, 3, 4]

Logical operators

To help combine multiple conditions
