To determine the length of an array

Is arr._len_() the only function that returns the array length?

As far as I know, I've learned that it's not good to write functions or variables that start with an underline (_), but I can't find any other way


python
list
array
size

len(s) functions.
I think you mentioned list when it comes to arrangement
In addition to list, len(s) takes sequence such as tuple and dict and collection type factors to return the length of the object.
mylist = [1,2,3,4,5]
len(mylist)

mytuple = (1,2,3,4,5)
len(mytuple)

mydict = {1:2, 2:3}
len(mydict)
