Using two different loops: $($for and while loop$),$ write a Python program that does the following:

$1.$ Display all the even numbers between $10$ and $100$

$2.$ Display all Odd numbers Backward from $999$ to $777$

$3.$ Using the While Loop, display all numbers moving by doubles starting from $20$ to $50,000,$ such as: $204080160320......$

$4.$ Ask the user the number of times to repeat, then store it in a variable and use it in a for and while loop to display "Programming Python" that number of times
