Python: Check the length and the fifth element occurs twice in a list

Python Programming Puzzles: Exercise-2 with Solution

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

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
