python how to count items in array

myArray = [1, 2, 3]
len(myArray)
#output
3

randomList = ['Hi', 'text', 420, 'Hello World', 'abcde', 'Sub2Technoblade']
print(len(randomList))

a = numpy.array([0, 3, 0, 1, 0, 1, 2, 1, 0, 0, 0, 0, 1, 3, 4])
unique, counts = numpy.unique(a, return_counts=True)
dict(zip(unique, counts))

# {0: 7, 1: 4, 2: 1, 3: 2, 4: 1}

#	How to use the .count function:

list = ["Elefant", "Snake", "Penguin", "Penguin"]

print(list.count("Penguin"))

# 	Explanation:
#   >(list name) + .count + (element)<
#   With the '.count' function Python counts how many of the elements you named are in the list.
#   In this case the output is '2' because The element 'Penguin' appears twice in the list.
