Python - Built in Functions Part 3: Mathematical and Logical Functions

These functions perform calculations and evaluate conditions.

Common Functions:

abs(): Returns the absolute value.

round(): Rounds a number to the nearest integer or specified decimal places.

pow(): Raises a number to a power.

min()/max(): Finds the smallest or largest value in an iterable.

all()/any(): Logical evaluation of iterables.

Examples:

Finding the absolute value:

num = -10

print(abs(num))  # Output: 10

Rounding a number:

num = 3.14159

print(round(num, 2))  # Output: 3.14

Logical evaluation with all():

conditions = [True, True, False]

print(all(conditions))  # Output: False

Explanation:

Mathematical and logical functions simplify calculations and decision-making in code. For example, abs() ensures non-negative values in computations, and all() evaluates whether all elements in a collection meet a specific condition.
