while c <= n: # Specifying the condition of the loop
# Beginning the code block
summation = c**2 + summation

c = c + 1 # Incrementing the counter
# Print the final sum
print(“The sum of squares is”, summation)
Explanation:

1 n = int(input(“Enter the limit: “)): Takes user input to set the upper limit for the loop. The int() function is used to
convert the input to an integer.
2 summation = 0: Initializes a variable summation to 0. This variable will store the sum of squares.
3 c = 1: Initializes a counter variable c with the value 1.

4 while c <= n:: The while loop continues as long as c is less than or equal to the specified limit.
5 summation = c**2 + summation: Calculates the square of c and adds it to the current value of summation.
6 c = c + 1: Increments the value of c by 1 in each iteration of the loop.
7 After the loop, print(“The sum of squares is”, summation): Prints the final sum of squares.
This program is a straightforward example of using a while loop to iteratively calculate the sum of squares.

Python For Loop

TASK 1: Python For Loop in Python String
Code:
# Iterating over a String
print(“String Iteration”)
s = input(“Enter the String: “)

foriin s:
print(i)
Explanation:
This code uses a for loop to iterate over a string and print each character on a new line. The loop assigns each
character to the variable i and continues until all characters in the string have been processed.
