Return the Next Number from the Integer Passed

Convert Minutes into Seconds

Learn how to convert minutes into seconds in Python using arithmetic multiplication and basic unit conversions.

1. The Challenge: Incrementing a Number

Create a function addition(num) that takes a number as an argument, increments the number by +1, and returns the result.

2. Why It Matters

Incrementing values is fundamental for counters, loop trackers, pagination, and game scoring mechanisms.

3. The Python Solution

Add 1 to the input parameter:

def addition(num):
    return num + 1

# Testing our function
print(addition(0))  # Output: 1
print(addition(9))  # Output: 10
print(addition(-3)) # Output: -2

4. Augmented Assignment Syntax

Inside functions or loop variables, you can also use the shorthand augmented assignment operator += 1:

counter = 5
counter += 1 # Equivalent to counter = counter + 1 (now 6)

5. Common Mistakes

• Expecting ++ Operator: Unlike C++ or JavaScript, Python does NOT have a num++ post-increment operator! Writing num++ in Python raises a SyntaxError. Always use num + 1 or num += 1.

6. Next Steps

Use num + 1 to increment values. Next, let's compute remainders using the Modulo operator!
