Python: Count the number of times a specific element presents in a deque object

Python Collections: Exercise-12 with Solution

Write a Python program to count the number of times a specific element appears in a deque object.

Sample Solution:

Python Code:

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

# Create a tuple 'nums' containing a sequence of numbers
nums = (2, 9, 0, 8, 2, 4, 0, 9, 2, 4, 8, 2, 0, 4, 2, 3, 4, 0)

# Create a deque 'nums_dq' from the 'nums' tuple
nums_dq = collections.deque(nums)

# Print a message to indicate the display of the count of number 2 in the sequence
print("Number of 2 in the sequence")

# Count and print the number of occurrences of 2 in 'nums_dq'
print(nums_dq.count(2))

# Print a message to indicate the display of the count of number 4 in the sequence
print("Number of 4 in the sequence")

# Count and print the number of occurrences of 4 in 'nums_dq'
print(nums_dq.count(4)) 

Sample Output:

Number of 2 in the sequence
5
Number of 4 in the sequence
4
