How to remove duplicate prints in Python?

So I wanted to write a program that would print out how many times a number is repeated in a list. I'm very new to Python and I used the .count() command to get the number of times an element is repeated. I want the output to follow the format "The number n is repeated n times".

This is what I have so far:

x = [1,1,2,4,5,7,2,3,3,8,2,3,6,7]
index = 0 
while index < len(x):
print('The number {} is repeated {} times.'.format(x[index],x.count(x[index])))
index = index + 1 

And this is the output:

The number 1 is repeated 2 times
The number 1 is repeated 2 times
The number 2 is repeated 3 times
The number 4 is repeated 1 times
The number 5 is repeated 1 times
The number 7 is repeated 2 times
The number 2 is repeated 3 times
The number 3 is repeated 3 times
The number 3 is repeated 3 times
The number 8 is repeated 1 times
The number 2 is repeated 3 times
The number 3 is repeated 3 times
The number 6 is repeated 1 times
The number 7 is repeated 2 times

I want the output to show how many times a number is repeated only once, and in ascending order. How can I make the output come out like this:

The number 1 is repeated 2 times.
The number 2 is repeated 3 times. 
The number 3 is repeated 3 times.

Thank you! :)
