Well, if len(list) is the length of a list, and range(N) is the integers from 0 to N-1, then range(len(list)) is the integers from 0 to 1 less than the length of the list, i.e., all the legal indices of the list.

What does Len 1 mean in Python?

len(A)-1 actually is the index of the last element in list A . As in python (and almost all programming languages), array indexes start from 0, so an array with n elements has index of 0, 1, 2, …, n-1 . Follow this answer to receive notifications. answered May 10, 2018 at 12:06. BookSword.

Is Len () of a list o 1 Python?

len is an O(1) because in your RAM, lists are stored as tables (series of contiguous addresses). To know when the table stops the computer needs two things : length and start point. That is why len() is a O(1), the computer stores the value, so it just needs to look it up.

Why is Len ()- 1?

len(A)-1 actually is the index of the last element in list A . As in python (and almost all programming languages), array indexes start from 0, so an array with n elements has index of 0, 1, 2, …, n-1 . @user The syntax A[-1] gives you the last value in the list. len(A)-1 gives you the last index.

What does range len ()- 1 do in Python?

In short, the for loop in Python "for i in range(len(list)-1, -1, -1)" is used to loop through all elements of a list in reverse order that is from end to first. We will start with a basic for loop in Python and incrementally change the code to arrive to Range len-1 in Python.

What does Len A 0 ]) mean in Python?

len (A [0]) indicates that it is taking the length of the first element in the array, so the loop starts at 0 through 3, which is the length of the first element. A[0] = [12, 7, 3]

Does length start at 0 Python?

The length of the empty string is 0. The len() function in Python is omnipresent – it's used to retrieve the length of every data type, with string just a first example.

What does Len ()- 1 mean?

@user The syntax A[-1] gives you the last value in the list. len(A)-1 gives you the last index.

What is Len () in range?

range(len(list)) is used to generate all sequence of indices in a list as the ending number is length of the list and the starting index is 0 so that last index is length-1.

Does .length start 0 or 1?

The beginning character of a string corresponds to index 0 and the last character corresponds to the index (length of string)-1 .

What is difference between Len and length?

Returns the length of an input string or binary value. For strings, the length is the number of characters, and UTF-8 characters are counted as a single character. For binary, the length is the number of bytes.
