Integer, Float, and Boolean data types in Python

Integer, Float, and Boolean data types in Python:

Integers (int):

Represent whole numbers without decimal points.
Examples:

Python

age = 25 # Stores the value 25 as an integer
year = 2024 # Stores the year as an integer
number_of_apples = 10 # Stores the number of apples as an integer

Floats (float):

Represent numbers with decimal points.
Used for precise measurements or calculations.
Examples:

Python

price = 19.99 # Stores the price as a float
pi = 3.14159 # Stores the value of pi as a float
distance = 123.456 # Stores the distance as a float

Booleans (bool):

Represent logical values: True or False.
Used for decision-making in code.
Examples:

Python

is_active = True # Stores a True boolean value
is_logged_in = False # Stores a False boolean value
has_completed_task = True # Stores a True boolean value

Key points:

Choose the appropriate data type based on the information you need to store.
Python automatically determines the data type based on the assigned value.
You can explicitly convert between data types using functions like int(), float(), and bool().

type(), float(), and int() functions in Python with examples:

type() function:

This function is used to check the data type of a variable.
It returns a class object representing the data type of the variable.

Examples:

Python

age = 30
print("Data type of age:", type(age)) # Output: <class 'int'>

pi = 3.14159
print("Data type of pi:", type(pi)) # Output: <class 'float'>

is_active = True
print("Data type of is_active:", type(is_active)) # Output: <class 'bool'>

float() function:

This function is used to convert a value to a floating-point number (float).
It can convert integers, booleans, and strings (if they represent a valid floating-point number) to floats.

Examples:

Python

converted_age_to_float = float(age)
print("Converted age to float:", converted_age_to_float) # Output: 30.0

converted_pi_to_int = int(pi)
print("Converted pi to integer (truncates decimals):", converted_pi_to_int) # Output: 3

# Boolean conversion (True remains True, False becomes 0)
converted_is_active_to_int = int(is_active)
print("Converted is_active to integer:", converted_is_active_to_int) # Output: 1

int() function:

This function is used to convert a value to an integer.
It can convert floats (truncating the decimal part) and booleans (True becomes 1, False becomes 0) to integers.
It raises a ValueError if the argument cannot be converted to an integer.
