Iteration in Python Quiz

1. Write a Python program to display all the prime numbers within a range using a for loop.

• for num in range(lower, upper + 1): if num > 1: for i in range(2, num): if (num % i) == 0: break else: print(num)

• for num in range(1, upper + 1): if num > 1: for i in range(2, num): if (num % i) == 0: break else: print(num)

• for num in range(upper, lower - 1, -1): if num > 1: for i in range(2, num): if (num % i) == 0: break else: print(num)

• for num in range(lower, upper + 1): if num > 1: for i in range(2, num + 1): if (num % i) == 0: break else: print(num)

2. How does a for loop work in Python? Provide an example.

• A for loop in Python can only iterate over a list

• The correct answer for the question is: A for loop in Python iterates over a sequence or iterable object, executing a block of code for each item in the sequence.

• A for loop in Python only works with integers

• A for loop in Python executes the block of code only once

3. Create a Python program to print the Fibonacci sequence using a while loop.

• Print the prime numbers using a do-while loop

• Print the Fibonacci sequence using a for loop

• Print the factorial sequence using a while loop

5. Write a Python program to display the multiplication table using nested loops.

• print('Multiplication table')

• for i in range(1, 11):

• for j in range(1, 11):

6. What are nested loops in Python? Provide an example.

• Nested loops are loops that only run once

• Nested loops are loops that cannot be used in Python

• Nested loops are loops that run in parallel

• Nested loops in Python are loops within a loop. They are used to iterate over multiple sequences or perform repetitive tasks. For example: for i in range(3): for j in range(2): print(i, j)

7. Write a Python program to iterate through a list and display the elements.

• print(my_list)

• while my_list: print(my_list.pop())

• for i in range(len(my_list)): print(my_list[i])

• for item in my_list: print(item)

8. Explain how to iterate through a list in Python with an example.

• for i in range(len(my_list)): print(my_list[i])

• while item in my_list: print(item)

• if item in my_list: print(item)

• for item in my_list: print(item)

9. Create a Python program to iterate through a dictionary and print its key-value pairs.

• print(my_dict.items())

• for key, value in my_dict.items(): print(key, value)

• for key, value in my_dict:

• for key in my_dict:

10. How can you iterate through a dictionary in Python? Provide an example.

• for key in my_dict:

• for item in my_dict:

• for value in my_dict.values():

• for key, value in my_dict.items():
