Reading input in python and converting keyboard input

reading input in python is a common task when developing programs that require user interaction. python provides several ways to read input from the keyboard, and the most commonly used methods are using the `input()` function and `sys.stdin`.
*using input() function:*
the `input()` function in python reads a line of text from the standard input (keyboard) and returns it as a string. here's an example of how to read input using the `input()` function:
in this example, the user is prompted to enter their name, and the input is stored in the variable `name`. the entered name is then printed back to the user.
*using sys.stdin:*
another way to read input in python is by using the `sys.stdin` object from the `sys` module. this method is commonly used in scenarios where you want to read multiple lines of input. here's an example of how to read input using `sys.stdin`:
in this example, the user can enter multiple lines of text, and the input is read using `sys.stdin.readlines()`. the entered lines are then printed back to the user.
*converting input to other data types:*
when reading input using the `input()` function, the input is always treated as a string. if you need to convert the input to other data types such as integers or floats, you can use type casting. here's an example of converting input to an integer:
in this example, the input is converted to an integer using the `int()` function before performing arithmetic operations.
remember to handle exceptions when converting input to other data types to prevent runtime errors if the input cannot be converted.
reading input in python is a fundamental skill that allows you to create interactive programs and gather user input to customize the program's behavior.
