Sample answer for fun :)
entered_number = int(input("Enter a number: "))
answers = [((i * (i + 1)) // 2) for i in range(1,entered_number) if ((i * (i + 1)) // 2) < entered_number]
#print the list
print(f"Triangular numbers up to {entered_number} : {answers}")
#print the answer for entered index
prompt = int(input(f"Enter a number between 0 to {int(len(answers))-1}: "))
print(f"The Triangular number as index {str(prompt)} is: {answers[prompt]}")
