statistics in python program wont output what i expect

I am trying to do a program for a class and it is supposed to take multiple values and output user selected statistic data. however all it does is asks for another selection.

Here is the code I have:

import statistics

values=[12,22,56,44,33,25,18,5,33,66]

print('#####################################################')

print('Choose from the MENU to perform given task ')

print('1- Calculate the mean value for the List')

print('2- Calculate the median value for the List')

print('3- Calculate the mode value for the List')

print('4- Calculate the Range value for the List')

print('5- Sort the values in ascending order in the List')

print('6- Calculate the standard deviation for the List')

print('-1 To EXIT')

print('#####################################################')

for i in range(7):
    user_in=int(input('What is your choice? '))
        if user_in == -1:
        break
else:
    while user_in != -1:
        if user_in == 1:
            mean_val=statistics.mean(values)
            print(f'Mean is {mean_val:.2f}')
            break
        elif user_in == 2:
            median_val=statistics.median(values)
            print(f'Median is {median_val:.2f}')
            break
        elif user_in == 3:
            mode_val=statistics.mode(values)
            print(f'Mode is {mode_val:.2f}')
            break
        elif user_in == 4:
            range_val=max(values)-min(values)
            print(f'Range is {range_val}')
            break
        elif user_in == 5:
            sort_val=sorted(values)
            print(f'Sorted {sort_val}')
            break
        elif user_in == 6:
            sd_dev=statistics.stdev(values)
            print(f'Standard Deviation {sd_dev:.2f}')
            break
        else:
            print('Invalid Entry')
            break
print('EXIT is selected')

I was expecting some sort of answer to be output but all that outputs is the program asking for selection.
