You can ask the user to pick a number now, check if it's the right size and, if it isn't, tell them it's not. What if you wanted it to keep going until you got an answer that was the right size? You could write if statements inside if statements, but what if the user still doesn't give you the right size of number?

You need a way to ask the question over and over until you get the right kind of answer. The way to do this in computer programming is called a loop. You're going to use one called the while loop.
A while loop is a bit like an if statement: it has code inside it that only runs if the condition in brackets is true. The difference is that a while loop runs over and over, until its condition is false. You have to make sure that there is always a way out of your while loops, or they'll run forever! It looks like this:
```
 while(my_number < 100):
     my_number = input("Hello "+name+" please pick a number that's bigger than 100")
     my_number = int(my_number)
```

Now add a while loop to your program.

 name = input("What is your name?")
 my_number = 0

 # Loop as long as "my_number" is less than 100
 while(my_number < 100):
     # Ask the user for a number
     my_number = input("Hello "+name+" please pick a number that's bigger than 100")
     # Convert the user's answer from a string to an integer
     my_number = int(my_number)
     print("Your number is "+str(my_number))
     # Check if the number is bigger than 100
     if(my_number > 100):
         print("That's a big number!").
     elif(my_number > 90):
         print("Almost there! Try again!")
     else:
         print("That number is too small! Please try again!")
     # If my_number is smaller than 100 at this point, loop again
