Python - Count elements in list

just do len(MyList)

This also works for strings, tuples, dict objects.

len(myList) should do it.

len works with all the collections, and strings too.

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
