What is slicing in Python?

In Python, slicing is a technique for accessing a portion of a sequence (such as a list, tuple, or string) by specifying a range of indices. The syntax for slicing is sequence[start:stop:step], where start is the index of the first element to include in the slice (inclusive), stop is the index of the last element to include in the slice (exclusive), and step is the step size between elements (default is 1).

Here are some examples of slicing:

# Slicing a list
my_list = [1, 2, 3, 4, 5]
print(my_list[1:4]) # [2, 3, 4]
print(my_list[2:]) # [3, 4, 5]
print(my_list[:3]) # [1, 2, 3]
print(my_list[::2]) # [1, 3, 5]
print(my_list[::-1]) # [5, 4, 3, 2, 1]

# Slicing a string
my_string = “hello world”
print(my_string[2:7]) # “llo w”
print(my_string[6:]) # “world”
print(my_string[:5]) # “hello”
print(my_string[::2]) # “hlowrd”
print(my_string[::-1]) # “dlrow olleh”
