In Python, we perform slicing using the following syntax: [start: end].
fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"]
sliced_fruits = fruits[1:3]
print(sliced_fruits) # ["Orange", "Lemon"]
Slicing in Python is very flexible. If we want to select the first n elements
of a list or the last n elements in a list, we could use the following code:
fruits[:n]
fruits[-n:]
fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"]
print(fruits[:3])
# ["Banana", "Orange", "Lemon"]
print(fruits[-2:])
# ["Apple", "Mango"]

# define a list
my_list = [1, 2, 3, 4, 5]
# get a slice of the list
sublist = my_list[1:3]
print(sublist) # [2, 3]
# get a slice from the beginning of the list
sublist = my_list[:3]
print(sublist) # [1, 2, 3]
# get a slice from the end of the list
sublist = my_list[3:]
print(sublist) # [4, 5]
# get a slice from the middle of the list
sublist = my_list[1:-1]
print(sublist) # [2, 3, 4]
# get the last two elements of the list
sublist = my_list[-2:]
print(sublist) # [4, 5]
# get all elements except the last two
sublist = my_list[:-2]
