Python also offers a more readable way to apply decorators using @ symbol: @my_decorator def say_hello(): print("Hello!") Running the say_hello() function would now result in: Something is happening before the function is called. Hello! Something is happening after the function is called...

Several escape sequences in Python allow you to represent ordinal values of ASCII characters using either the hexadecimal or octal numeral system. For example, the ordinal value of the asterisk symbol (*) is 42 in decimal, which is equal to 2a16 in hexadecimal and 528 in octal: Python >...
in writing you can use words like “parens” and “bracketed” instead of using curved symbol – additionally when programming some languages allow users alternate ways to represent parenthetical grouping e.g., python allows us use indentation instead although this might not work too great if we ...
