Indexing: Indexing in Python is a way to access individual elements of a sequence (like a string, list, or tuple) using their position.
Slicing: Slicing allows you to extract a subsequence from a sequence by specifying a start, stop, and step value.
Step-by-Step Process
Indexing: Use square brackets [] to access an element by its position in the sequence. Index starts at 0 for the first element, and -1 refers to the last element. Works with strings, lists, tuples, and other sequence types.
Slicing: Start: Index of the first element to include (default is 0). Stop: Index of the first element to exclude. Step: The interval between elements (default is 1).
Sample Code
# String indexing
text = "Vignesh"
print("Output for string index:")
print(text[0])
print(text[3])
print(text[-1])
print()
# List indexing
numbers_1 = [10, 20, "Kumar", 40, "Apple","Orange",100]
print("Output for list index:")
print(numbers_1[2])
print(numbers_1[5])
print(numbers_1[-3])
print()
# String slicing
text = "Computer"
print("Output for string slice:")
print(text[1:4])
print(text[:3])
print(text[2:])
print(text[::2])
print()
# List slicing
numbers_2 = [10, 20, "Kumar", 40, "Apple","Orange",100]
print("Output for list slice:")
print(numbers_2[1:4])
print(numbers_2[:3])
print(numbers_2[::2])
