Counting Items in a List in Python
To find the number of matches of an element in a list, we use the count method. In its parameter, we specify the element we need:
pythonlst = [1, 2, 1, 3]
print(lst.count(1)) # 2
Let's try to find an element that is not in the list:
pythonlst = [1, 2, 1, 3]
print(lst.count(4)) # 0
