FOR LOOP 

In Python, a for loop is used to iterate over a sequence (such as a list, tuple, string, or range) or any iterable object. The loop iterates over each item in the sequence and executes a block of code for each iteration. The general syntax of a for loop in Python is as follows


SYNTAX:

for item in sequence:
    # code block to be executed for each item

Here's a breakdown of each part:

  • In this example, variable is a placeholder representing the loop variable that will take on each value from the sequence during each iteration of the loop. The loop will continue executing the code block until it has processed all the elements in the sequence.

    Let's see a specific example in Python where we use a for loop to print the numbers from 1 to 5:

  • EXAMPLE CODE:

  • for i in range(1, 6): print(i)

  • OUTPUT:

  • 1

    2

    3

    4

    5

  • In this example, range(1, 6) generates a sequence of numbers from 1 to 5 (inclusive). During each iteration, the loop variable i takes on the next value from the sequence, and the print(i) statement outputs the value of i to the console.

    You can customize the behavior of a for loop based on your requirements. The sequence can be a range of numbers, a list, a string, or any iterable object depending on the programming language you are using.

DISTANCE BETWEEN TWO POINT

-
distance between two points python code import math def calculate_distance(x1, y1, x2, y2): distance = math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2) return distance # Example usage: x1 = 1 y1 = 2 x2 = 4 y2 = 6 distance = calculate_distance(x1, y1, x2, y2) print("The distance between the two points is:", distance) OUTPUT: The distance between the two points is: 5.0 In this code, the calculate_distance() function takes the coordinates of two points (x1, y1) and (x2, y2) as input parameters. It uses the distance formula to calculate the distance and returns the result. The math.sqrt() function from the math module is used to calculate the square root of the expression (x2 - x1) ** 2 + (y2 - y1) ** 2. Finally, an example usage is provided, where the coordinates of the two points are assigned to variables x1, y1, x2, and y2. The calculated distance is then printed to the console.

RETURN VALUE

RETURN VALUE In Python, you can return values from functions using the return statement. The return statement allows you to send a value back to the caller of the function. Here's an example code that demonstrates returning values in Python: distance between two points python code def add_numbers(a, b): return a + b result = add_numbers(5, 3) print(result) # Output: 8 In the above example, we have a function named add_numbers that takes two arguments a and b . Inside the function, we use the return statement to send back the sum of a and b . When we call the add_numbers function with 5 and 3 , it returns the sum 8 . We store the returned value in the result variable and then print it to the console. Here's another example that demonstrates returning multiple values from a function: def get_name_length(name): length = len(name) is_long = length > 5 return length, is_long name_length, is_name_long = get_name_l...
