Quick Preview

message = "Hello, Python!"

print(message[0])        # H
print(message[-1])       # !
print(message[7:13])     # Python
print(message.upper())   # HELLO, PYTHON!
print(len(message))      # 14

Strings are immutable — once created, they can’t be changed in place. Every string operation returns a new string.
