✅ Python Data Types! 🐍✨
Data types define what kind of value a variable stores in Python.
name = "Python"
age = 25
price = 99.99
is_easy = True
1. String (str):
Used to store text values.
language = "Python"
city = 'Delhi'
✔ Written inside quotes "" or ''
✔ Used for names, messages, text data
2. Integer (int):
Used to store whole numbers.
age = 25
marks = 95
✔ No decimal point
✔ Positive or negative numbers allowed
3. Float (float):
Used to store decimal numbers.
price = 99.99
temperature = 36.6
✔ Numbers with decimal values
4. Boolean (bool):
Used for True or False values.
is_logged_in = True
is_admin = False
✔ Mostly used in conditions and comparisons
5. List (list):
Stores multiple values in one variable.
fruits = ["apple", "banana", "mango"]
✔ Ordered collection
✔ Can store duplicate values
✔ Uses square brackets []
6. Tuple (tuple):
Similar to list but cannot be changed.
colors = ("red", "blue", "green")
✔ Immutable unchangeable
✔ Uses parentheses ()
7. Set (set):
Stores unique values only.
nums = {1, 2, 3, 3, 4}
print(nums)
✔ Output → {1, 2, 3, 4}
✔ Removes duplicates automatically
8. Dictionary (dict):
Stores data in key-value pairs.
student = {
"name": "Alex",
"age": 22
}
✔ Uses curly braces {}
✔ Access values using keys
9. Check Data Type:
Use type() to check variable type.
name = "Python"
print(type(name))
✔ Output →
10. Type Conversion:
Convert one data type into another.
age = int("25")
price = float("99.5")
✔ int() → Integer
✔ float() → Decimal
✔ str() → String
11. Practice Examples:
✔ Add integers
a = 10
b = 20
print(a + b)
✔ Print list items
fruits = ["apple", "banana"]
print(fruits)
✔ Access dictionary value
student = {"name": "Alex"}
print(student["name"])
💡 Understanding data types is important because every Python program uses them.
