Certainly! Here are some basic do’s and don’ts for coding standards, along with sample code snippets to illustrate them:

DO’s

1. Use clear and descriptive variable, function, and class names:

# Variable

customer_name = “John Smith”

total_amount = 100.50

# Function and Class

def calculate_total_amount(items):

    pass

class Customer:

    def __init__(self, name):

        self.name = name

Proper names must be given to even Directories and Files
Directories – small case
Files – Camel Case 

2. Follow proper indentation and formatting:

// indentation of 2 space

if (condition) {

    statement1;

    statement2;

} else {

    statement3;

}

3. Comment your code to provide clarity and explanations:

// explain the purpose of the code at start

int result = calculateTotalAmount(items); // Calculate the total amount of items

// describe the behavior of a function or method

/**

 * Returns the sum of the given array of numbers.

 * @param numbers The array of numbers

 * @return The sum of the numbers

 */

public int calculateSum(int[] numbers) {

    // Code to calculate the sum

}

DONT’S

1. Avoid using magic numbers or hard-coded values:

// Magic number without explanation [Random]

int result = calculateSomething(42);

// Use a named constant or variable

int defaultValue = 42;

int result = calculateSomething(defaultValue);

2. Don’t use excessive or unnecessary comments:

# Redundant comment

x = x + 1  # Increment x by 1

3. Avoid long and complex functions or methods:

// Long and complex function – Unnecessary increases line of code

function processOrder(order) {

    // A lot of code…

    // More code…

    // Even more code…

    // …

    // Code continues…

}
