print('hello there')
print('what is your name?')
while True:
    myName = input()
    try:
        if str(myName) == True:
            print('your name is ' + myName + ', it is nice to meet you')
            print('the length of your name is composed of ' + str(len(myName)) + ' letters.')
        else:
            print('Please use the alphabet instead of the number')
         
        continue
        print('what is your age?')
 
        while True:
            myAge = input()
            try:
                myAge = int(myAge)
                print('thank you')
            except ValueError:
                print(f"{myAge} isn't a number. Please enter a number!")
        pass
    except:
        print('thank you') 
        print('you will be ' + str(int(myAge) + 1) + ' next year')
        print('this is the end of this program')

it works but it ends first loop and print wrong sentences and don't ask second question also...

Output:
hello there
[b]what is your name?[/b]
Samuel
[b]Please use the alphabet instead of the number[/b]
