Why isn't this code not working properly? Python loop not breaking properly [on hold]

Question

I am trying to get the names and country codes for each person in the class and putting them into a list of tuples. My trouble is that it is not looping back if name is not alphabetic. Any help?

mylist = []

for x in range(2):
    while True:
        name = input("what is your name?: ")
        numCode = input("what is your country phone code? (+44): ")
        if name.isalpha():
            break
    mylist.append([name, numCode])

print(mylist)

edit Here it shows the program breaks and continues to the next logic even if name.isalpha() is false

what is your name?: 11

what is your country phone code? (+44): aa

what is your name?: 11

what is your country phone code? (+44): aa

what is your name?: aa

what is your name?: 11

what is your country phone code? (+44): 11

what is your name?: aa
[['aa', 'aa'], ['aa', '11']]

Answer 1

When running the original myself on python 3.6 and 3.7 I found that it did loop back. Are you sure this is the problem?

Simplified:

print(input('Input: ').isalpha())

eg tests:

>>> print(input('Input: ').isalpha())
Input: 123
False
>>> print(input('Input: ').isalpha())
Input: abc
True
>>> print(input('Input: ').isalpha())
Input: abc123
False
