List Built-in Functions

A number of built-in functions create or deal with lists. The following functions apply to all sequences, including tuples and strings.

len( object ) → integer

Return the number of items of a sequence or mapping.

max( list ) → value

Return the largest item in the sequence.

min( list ) → value

Return the smallest item in the sequence.

any( tuple ) → boolean

Return True if there exists an item in the sequence which is True.

all( tuple ) → boolean

Return True if all items in the sequence are True.

range( [start] , stop , [step] ) → list of int

The arguments must be plain integers. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. The full form returns a list of plain integers [ start , start + step , start + 2 * step , ...]. If step is positive, the last element is the largest start + i * step less than stop ; if step is negative, the last element is the largest start + i * step greater than stop . step must not be zero (or else ValueError is raised).
