lists in python

1listName = [1,2,3,4]

1# list() converts other datatypes into lists

5text = 'Python'

7# convert string to list
8text_list = list(text)
9print(text_list)

11# check type of text_list
12print(type(text_list))

17my_list.remove(x) # remove first occurance of x from list
18my_list.pop([i]) # pop element at index i (defaults to end of list)
19my_list.clear() # delete all elements from the list
20my_list.index(x[, start[, end]]) # return index of element x
21my_list.count(x) # return number of occurances of x in list
22my_list.reverse() # reverse elements of list in-place (no return)
23my_list.sort(key=None, reverse=False) # sort list in-place
24my_list.copy() # return a shallow copy of the list
