print(len(my_string)) # Output: 13 The len() function returns the number of characters in the string, including spaces and punctuation. List Length: python my_list = [1, 2, 3, 4, 5] print(len(my_list)) # Output: 5 This returns the number of elements in the list. Tuple Leng...
The len() function takes a single object as argument. It can be: Sequence - list, tuple, string, range, etc. Collection - set, dictionary etc. len() Return Value It returns an integer (the length of the object). Example 1: Working of len() with Tuples, Lists and Range x = [1...

In this section, you’ve used the len() Python function with strings, lists, tuples, and range objects. However, you can also use the function with any other built-in sequence.Using len() With Built-in CollectionsAt some point, you may need to find the number of unique items in a ...
Thelen()function is a library function in Python, it is used to get the length of an object (the object may astring,list,tuple, etc). It accepts an object and returns its length (total number of characters in case of a string, the total number of elements in case of an iterable). ...
