A factorial program is a program that calculates the factorial of a given number.

• Factorial of a number is the product of all positive integers up to that number.

• For example, the factorial of 5 (5!) is 5 x 4 x 3 x 2 x 1 = 120.

• Factorial program can be implemented using loops or recursion in programming languages like C, Java, Python, etc.

A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.

• Check if the number is greater than 1.

• Loop through numbers from 2 to the square root of the number and check if any of them divides the number evenly.

• If no divisor is found, the number is prime.

To check if a number is even, divide it by 2 and see if there is a remainder.

• Divide the number by 2

• If there is no remainder, the number is even

• Example: 6 divided by 2 equals 3 with no remainder, so 6 is even

Python language is interpreted because it is executed line by line at runtime by the Python interpreter.

• Python code is not compiled into machine code before execution

• Python interpreter reads the code line by line and executes it immediately

• This allows for easier debugging and dynamic typing

Data types in Python include integers, floats, strings, lists, tuples, dictionaries, and booleans.

• Integers are whole numbers without decimals (e.g. 5, -3)

• Floats are numbers with decimals (e.g. 3.14, -0.5)

• Strings are sequences of characters enclosed in quotes (e.g. 'hello', '123')

• Lists are ordered collections of items (e.g. [1, 'apple', True])

• Tuples are similar to lists but immutable (e.g. (1, 'banana', False))
