10. Remove All Elements from a Deque

Write a Python program to remove all the elements of a given deque object.

Sample Solution:

Python Code:

# Import the collections module to use the deque data structure
import collections

# Create a tuple 'odd_nums' containing odd numbers 1, 3, 5, 7, and 9
odd_nums = (1, 3, 5, 7, 9)

# Create a deque 'odd_deque' from the 'odd_nums' tuple
odd_deque = collections.deque(odd_nums)

# Print a message to indicate the display of the original deque with odd numbers
print("Original Deque object with odd numbers:")

# Print the 'odd_deque' containing odd numbers
print(odd_deque)

# Print a message displaying the length of the 'odd_deque'
print("Deque length: %d" % (len(odd_deque)))

# Clear all elements from the 'odd_deque'
odd_deque.clear()

# Print a message to indicate the display of the 'odd_deque' after removing all numbers
print("Deque object after removing all numbers-")

# Print the empty 'odd_deque'
print(odd_deque)

# Print a message displaying the length of the empty 'odd_deque'
print("Deque length:%d" % (len(odd_deque)))

Sample Output:

Original Deque object with odd numbers:
deque([1, 3, 5, 7, 9])
Deque length: 5
Deque object after removing all numbers-
deque([])
Deque length:0
