Variables in Python
1. What is a Variable?
- A variable stores information
- It has a name and a value
- Helps avoid repeating values
2. String Variable
Example:
name = "Spongebob"
print(name)- Quotes → string
- Without quotes → variable
3. Using f-strings
- f-strings mix text and variables
Example:
print(f"My name is {name}")The text inside the curly bracket is a variable and will replace the value of the variable. For example name = "John"; so wherever you use name it will replace with John.
4. Integer Variable
age = 20
print(f"I am {age} years old")Here age will replace 20 as the value of age is 20.
5. Float Variable
price = 10.99
print(f"Price is {price}")6. Boolean Variable
is_student = True
print(is_student)It will print True as the value of is_student variable is True. If it’s false then it will print False.
7. Summary
- Variables store data
- f-strings combine text & variables
