Python: Find the indexes of numbers, below a given threshold
Indices Below Threshold
Write a Python program to find the indexes of numbers in a given list below a given threshold.
Input: [(100,(0, 12, 45, 3, 4923, 322, 105, 29, 15, 39, 55))] Output: [0, 1, 2, 3, 7, 8, 9, 10] Input: [(10,(0, 12, 4, 3, 49, 9, 1, 5, 3))] Output: [0, 2, 3, 5, 6, 7, 8]

Sample Solution:
Python Code:
# License: https://bit.ly/3oLErEI
# Define a function named 'test' that takes a list of numbers 'nums' and a threshold 'thresh' as input
def test(nums, thresh):
# Use a list comprehension to find the indexes (i) of numbers in 'nums' that are below the given threshold 'thresh'
return [i for i, n in enumerate(nums) if n < thresh]
# Create a list of numbers 'nums' with specific elements
nums = [0, 12, 45, 3, 4923, 322, 105, 29, 15, 39, 55]
# Assign a threshold value 'thresh' to the variable
thresh = 100
# Print the original list of numbers
print("Original list:")
print(nums)
# Print the threshold value
print("Threshold: ", thresh)
# Print a message indicating the operation to be performed on the list
print("Check the indexes of numbers of the said list below the given threshold:")
# Print the result of the test function applied to the 'nums' list with the given threshold value
print(test(nums, thresh))
# Create a different list of numbers 'nums' with specific elements
nums = [0, 12, 4, 3, 49, 9, 1, 5, 3]
# Assign a different threshold value 'thresh' to the variable
thresh = 10
# Print the original list of numbers
print("\nOriginal list:")
print(nums)
# Print the updated threshold value
print("Threshold: ", thresh)
# Print a message indicating the operation to be performed on the list
print("Check the indexes of numbers of the said list below the given threshold:")
# Print the result of the test function applied to the modified 'nums' list with the updated threshold value
print(test(nums, thresh))
Sample Output:
Original list: [0, 12, 45, 3, 4923, 322, 105, 29, 15, 39, 55] Threshold: 100 Check the indexes of numbers of the said list below the given threshold: [0, 1, 2, 3, 7, 8, 9, 10] Original list: [0, 12, 4, 3, 49, 9, 1, 5, 3] Threshold: 10 Check the indexes of numbers of the said list below the given threshold: [0, 2, 3, 5, 6, 7, 8]
