🔢 Python Data Types

In Python, every value has a **data type**. Python automatically assigns the data type when a value is assigned to a variable.

🧮 Basic Built-in Data Types

• int - Integer numbers
• float - Decimal numbers
• str - String/text
• bool - Boolean values (True or False)
• list - Ordered, mutable collection
• tuple - Ordered, immutable collection
• set - Unordered, unique collection
• dict - Key-value pairs

🔍 Examples

# Integer
x = 10
print(type(x))  # <class 'int'>

# Float
y = 3.14
print(type(y))  # <class 'float'>

# String
name = "Python"
print(type(name))  # <class 'str'>

# Boolean
is_ready = True
print(type(is_ready))  # <class 'bool'>

# List
colors = ["red", "blue", "green"]
print(type(colors))  # <class 'list'>

# Tuple
points = (4, 5, 6)
print(type(points))  # <class 'tuple'>

# Set
unique_values = {1, 2, 3}
print(type(unique_values))  # <class 'set'>

# Dictionary
student = {"name": "John", "age": 20}
print(type(student))  # <class 'dict'>
  

📦 Dynamic Typing

Python is dynamically typed, so you don’t need to declare a data type. Python figures it out automatically.

data = 42         # int
data = "Now text" # str
  

🧪 Check Data Type

Use the type() function to check any variable's data type.

print(type(100))       # <class 'int'>
print(type("hello"))   # <class 'str'>
