List - Basic

List

A list is a collection which is ordered and changeable. In Python lists are written with square brackets.

Create a List:

list = ["aaa", "bbb", "ccc"]

Access Items with slicing

To access values in lists, use the square brackets for slicing along with the index or indices to obtain value available at that index.

my_list = ['p','r','o','g','r','a','m']

print(my_list[2:5])

print(my_list[:-5])

print(my_list[5:])

print(my_list[:])

Output

['o', 'g', 'r']

['p', 'r']

['a', 'm']

['p', 'r', 'o', 'g', 'r', 'a', 'm']

	P	R	O	G	R	A	M
Positive index	0	1	2	3	4	5	6
Negative index	-7	-6	-5	-4	-3	-2	-1
