Python: Check the length and the fifth element occurs twice in a list
Python Programming Puzzles: Exercise-2 with Solution
Fifth Element and List Length Check
Write a Python program that accepts a list of integers and calculates the length and the fifth element. Return true if the length of the list is 8 and the fifth element occurs thrice in the said list.
Input: [19, 19, 15, 5, 5, 5, 1, 2] Output: True Input: [19, 15, 5, 7, 5, 5, 2] Output: False Input: [11, 12, 14, 13, 14, 13, 15, 14] Output: True Input: [19, 15, 11, 7, 5, 6, 2] Output: False

Sample Solution:
Python Code:
# License: https://bit.ly/3oLErEI
# Define a function named 'test' that takes a list 'nums' as input
def test(nums):
# Check if the length of 'nums' is 8 and the count of the fifth element in 'nums' is equal to 3
return len(nums) == 8 and nums.count(nums[4]) == 3
# Create a list 'nums' with specific elements
nums = [19, 19, 15, 5, 5, 5, 1, 2]
# Print the original list
print("Original list:")
print(nums)
# Print the result of the test function applied to the 'nums' list
print("Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. :")
print(test(nums))
# Create a different list 'nums' with specific elements
nums = [19, 15, 5, 7, 5, 5, 2]
# Print the original list
print("\nOriginal list:")
print(nums)
# Print the result of the test function applied to the modified 'nums' list
print("Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. :")
print(test(nums))
# Create another list 'nums' with specific elements
nums = [11, 12, 14, 13, 14, 13, 15, 14]
# Print the original list
print("\nOriginal list:")
print(nums)
# Print the result of the test function applied to the modified 'nums' list
print("Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. :")
print(test(nums))
# Create one more list 'nums' with specific elements
nums = [19, 15, 11, 7, 5, 6, 2]
# Print the original list
print("\nOriginal list:")
print(nums)
# Print the result of the test function applied to the modified 'nums' list
print("Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. :")
print(test(nums))
Sample Output:
Original list: [19, 19, 15, 5, 5, 5, 1, 2] Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. : True Original list: [19, 15, 5, 7, 5, 5, 2] Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. : False Original list: [11, 12, 14, 13, 14, 13, 15, 14] Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. : True Original list: [19, 15, 11, 7, 5, 6, 2] Check whether the length of the said list is 8 and fifth element occurs thrice in the said list. : False
