📦 Variables and input

Variables

name = "Maya"
age = 12
print(name)
print(age + 1)

A variable is a name for a value. = means “store” (not “equals” like in math). Now name holds "Maya" and age holds 12.

Naming rules

input

name = input("What is your name? ")
print("Nice to meet you, " + name + "!")

input waits for the user to type and press Enter, and returns what they typed — always as a string.

Numbers from input

age = int(input("How old are you? "))
print("Next year you will be", age + 1)

int() turns the string "12" into the number 12. Use float() for decimals like 3.5. print with commas adds spaces between items.

Tip

💡 f-strings make printing easy: print(f"Hi {name}, you are {age}") — put an f before the quotes and variables in {curly braces}.
