Categorized request examples and articles tagged with [list-length] keyword How do I get the length of a list in Python?
To get the length of a list in Python, you can use the len(list) function. The len() function works similarly with other data structures, including tuples, sets, and dictionaries. The list's size is not fixed; the user can add or remove data to the list during execution time. The len() method always returns the actual size of the list. It does not calculate the size of the list every time it is used; instead, it uses a pre-computed and cached value for the list's size, which makes the len() method very fast.
