Python - Count elements in list [duplicate]
I am trying to find a simple way of getting a count of the number of elements in a list:
MyList = ["a", "b", "c"]
I want to know there are 3 elements in this list.
Solution 1:
len()
>>> someList=[]
>>> print len(someList)
0
Solution 2:
just do len(MyList)
This also works for strings
, tuples
, dict
objects.
Solution 3:
len(myList)
should do it.
len
works with all the collections, and strings too.
Solution 4:
len()
it will count the element in the list, tuple and string and dictionary, eg.
>>> 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
