Document Summary
E. g. ) list_name = [ a", b", c", 1, 2, 3, 4] E. g. ) list_name [1:5], will return [b, c, 1, 2] (right before 5th element) E. g. ) list_name[2] = cmpt, then if print list_name[2]will return cmpt, not 2. First initiate the variable with a list object name, then use square brackets to store the values separated by commas. Use slicing on left-hand side of assignment operator: Use del statement (if you know which element you are deleting) or remove() (if you don"t know which element you are deleting): len([list]) - returns length of list, number of elements in list. [list1] + [list2] - concatenates two list into one, returns [list1, list2] E. g. ) del list_name[2] [ a", c", 1, 2, 3, 4] What is the different between append() and extend()? list(tuple) - converts tuple into a list. Append takes a argument that can be any data type and adds it to the end of a list.
