Answer in one word or one sentence

1. What is a break statement in Python?

The break statement is used to exit the loop

2. Write a Python code to execute an infinite loop.

while True:

print("hello")

3. What is a pass statement in Python?

The pass statement is used as a placeholder for future code.

4. What is a nested loop?

A loop inside another loop is called a nested loop

5. What is range function?

The range function generates a sequence of numbers within a specified range.

Answer the following

1. What is the use of Loop in Python.

A loop in Python is used to execute a block of code repeatedly. It allows you to perform the same actions multiple times without having to write the code again and again.

2. What are the loops available in Python?

·         while: A while loop repeatedly executes a target statement as long as a given condition is true.

·         for: for loop is generally used when you know how many times you have to repeat a task.

3. What is a range function in python?

The range() function returns a sequence of numbers, starting from 0 by default, increments by 1 (by default), and ends at a specified number.

4. What are loop control statements in Python?

Loop control statements in Python, like break, continue, and pass, help manage the flow of loops. break stops the loop entirely, continue skips the current iteration, and pass is a placeholder for future code.

5. Write a program to print all the numbers below 50 which are divisible by 7 ?

for num in range(0,50):

if num % 7 == 0:

print(num)
