A program that asks you to enter anything and after entering it gives 'Ok', but if you just press Enter without entering anything, the program will stop. How to do?

Question

Python

Can't get the desired result. Enter is recognized as a letter.

z = input ("Введите что-нибудь:  ")

#число
if type (z) == int:
   print ("Ok")

#дробное число
elif type (z) == float:
   print ("Ok")

#текст
elif type (z) == str:
   print ("Ok")

#Enter
elif

Answer 1

while input('Введите что-нибудь: '):
    print('Ok')

Answer 2

To test z for type, you must first cast z to the correct type. And you will always have a string in the z variable (until you manually convert it to another type)
