This code snippet uses one function. The count_occurance function counts how many times a number appears in the “values” list. This function iterates over all the values in “values” and keeps a running total of all those equal to a particular number. This number is specified as a parameter called “to_find”.

iterate_integer_values.py

def count_occurrence(values, to_find):
	number_of_occurrences = 0
	for v in range(len(values)):
		if values[v] == to_find:
			number_of_occurrences += 1
	return number_of_occurrences

values = [1, 2, 3, 3]
check_for_threes = count_occurrence(values, 3)

print(check_for_threes)
