Example 1: python find the number of elements in a list
list1 = [2,3,4,3,10,3,5,6,3]
elm_count = list1.count(3)
print('The count of element: 3 is ', elm_count)
Example 2: python number of elements in list of lists
# Basic syntax:
# Using list comprehension:
sum([len(elem) for elem in list_of_lists])
# Example usage:
# Say you want to count the number of elements in a nested list like:
nested_list = [ [1, 2, 3, 45, 6, 7],
[22, 33, 44, 55],
[11, 13, 14, 15] ]
sum([len(elem) for elem in nested_list])
--> 14
Example 3: how to find the amount of numbers in a list on python
>>> someList=[]
>>> print len(someList)
0
Example 4: number of elements list python
>>> mylist = [1,2,3] #list
>>> len(mylist)
3
>>> word = 'hello' # string
>>> len(word)
5
>>> vals = {'a':1,'b':2} #dictionary
>>> len(vals)
2
>>> tup = (4,5,6) # tuple
>>> len(tup)
3
Example 5: number of elements in list in python
# List of strings
listOfElems = ['Hello', 'Ok', 'is', 'Ok', 'test', 'this', 'is', 'a', 'test']
len(s)
Example 6: count number items in list python
mylist = ["abc", "def", "ghi", "jkl", "mno", "pqr"]
print(len(mylist))
# output 6
