Answer 1

Lenoname ,

we have already been discussing this issue earlier today, so this is a duplicate of: https://www.sololearn.com/Discuss/2990339/?ref=app

we are missing some parts of your code (i assume that *Person* is a class, that has 3 attributs, and *p* is an instance of class Person. so *p.name* returns a string from instance attribut name ... )

but here is a simple answer:

<string>.isalpha() is a python string method that returns True, if all characters of the given string are letters.

"Hello".isalpha() => True
"hello world".isalpha() => False, since there is a whitespace in the string
"hello1".isalpha() => False, since there is a digit in the string

Lenoname ,

yes, you can write it like you mentioned it and how it is shown in this code:

try:
p = Person(input("name: "),int(input("age: ")),input("sex: "))
assert p.name.isalpha() and p.sex.isalpha()
print("name and sex are strings")
except:
print("wrong, try again")

this code is reworked because wrong quotes for the strings are used. there is also a mix of tabs and spaces fod indentation in your 2 code parts.

Answer 3

Lothar The missing parts are:
class Person:
def __init__(self, name, age, sex):
self.name = name
self.age = age
self.sex = sex

def __str__(self):
return f'{self.name},{self.age},{self.sex}'

def __repr__(self):
return f'{self.name},{self.age},{self.sex}'
I know about that, but how do i check wether p.name is alpha?can i even write it like that?: p.name.isalpha()
