What are Variables?
A variable is like a labeled box that stores a value. You give the box a name, and you can put something inside it.
Creating Variables
Use = to store a value in a variable:
python
name = "Alex"
age = 10
Types of Values
Strings — text inside quotes:
python
color = "blue"
greeting = 'Hello!'
Integers — whole numbers:
python
score = 100
lives = 3
Booleans — True or False:
python
is_happy = True
is_raining = False
Using Variables
You can use variables in print():
python
name = "Alex"
print(name)
Output:
text
Alex
You can print variables with text:
python
name = "Alex"
print("Hello,", name)
Output:
text
Hello, Alex
Changing Variables
You can change what's inside a variable:
python
score = 0
print(score)
score = 100
print(score)
Output:
text
0 100
The old value is replaced by the new one.
