Module 3: Operators in Python
Assignment Operators
Assignment operators update a variable. = stores a value; shortcuts like += add and assign in one step.
About 8 minutes
The = operator
= is not “equals” in math — it means “put this value in the variable”.
Example code
points = 0 points = points + 10 print(points) # 10
Shortcut operators
- += add and assign
- -= subtract and assign
- *= multiply and assign
- /= divide and assign
Example code
score = 50 score += 5 # same as score = score + 5 print(score) # 55 score *= 2 print(score) # 110
Practice
Start with savings = 100. Add 25, then multiply by 2. Print after each step.
Key takeaways
- = assigns a value to a variable.
- +=, -=, *=, /= update the variable in one line.
- Shortcuts make code shorter and clearer.
