The string data type (literally meaning a string of characters) is very commonly used in your Python scripts that use  I/O (input and output). Any input you get via the `input()` function is initially saved and handled as a string. Luckily, Python has many built in methods specifically for string objects, which you can use to validate input or process any string.

In this assignment, you will use Python’s built-in string methods to interact with the string:

`sentence = “Python is my favorite programming language!”`

Write a program called ``, in which you define the string above. After defining it, you will use string methods to perform the next tasks:

  1. Print the full string as it is.
  2. Print a version of the string with only uppercase letters.
  3. Print the number of times the letter ‘o’ is present in the string.
  4. Print a version of the string in which “my” is replaced with “everyone’s”.
  5. Print True if all characters in the string are alphabetical, print False if not.
  6. Print True if all characters are ASCII characters, print False if not.
  7. Print True if all characters in the string are digits, print False if not.

Please note that all of the above is hardcoded and will result in the same output every time.

Example usage:

-!- CODE language-bash -!-$ python3
Python is my favorite programming language!
