why does it print length of the list 1 when there are 3 elements in my list

n=int(input()) 
arr=[input().split(",")] 
e=len(arr) 
print(e)

the input I gave is n=3 and arr=1,0,2 and its output is 1 why does it print the length of list as 1 instead 3 since it has 3 elements. if it is wrong way to use what should I use in its place

input().split(",") statement returns a list. By using [input().split(",")] you are adding retuned list into another list making it a 2D list. According to your code arr = [[1,0,2]]. You are getting the length of this 2D list which is 1.

You are wrapping [input().split(",")] in a list, so there is only one element (arr will be a list containing a single list).

Use instead: arr=input().split(",")
