python contd

• Lets solve Project Euler 3

def is_prime(number:int) -> bool:
    """Checks if the number is prime or not

    Args:
        number (int): number

    Returns:
        bool: True if prime False otherwise
    """
    if number < 2:
        return False
    result = True
    index = 2
    while index <= number // 2:
        if number % index == 0:
            result = False
            break
        index += 1
    return result

number = 13195
index = number // 2
result = 0
while index >= 2:
    if number % index == 0: # factor
        if is_prime(index):
            result = index
            break
    index -= 1
print(result)

Functions in python

• A function is reusable code block
• syntax

def <name>(<args>):
    ...
    ...

• Refer Here for programiz tutorial
• Refer Here for some examples

docstring

• Docstrings can document modules, classes and functions
• Using docstring we can generate the documentation.
• For docstrings we would be using google style guide
• Prompt

As a python expert, Give me some examples for function doc strings 

• Install an extension autoDocstring from vscode

Casing

• CAMEL Casing

index
myIndex

• Pascal Casing

Index
MyIndex

• Snake Casing: In python to define variables and functions snake casing is recommended

index
my_index

• Lets write a python function to calulate factorial of a number

5! = 5 * 4 * 3 * 2 * 1

• Refer Here for some solutions.
