Lenoname ,
why not trying this:
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}"
#Initialize an instance of the object:
A = Person("John", 34, "Male")
personList = []
print(A) # this uses __str___
personList.append(A)
print(personList) # this uses __repr__

Lenoname ,
this is an explanation from the official python documentation:
object.__repr__(self):
called by the repr() built-in function and by string conversions (reverse quotes) to compute the "official" string representation of an object.
object.__str__(self):
called by the str() build-in function and by the print statement to compute the "informal" string representation of an object.

Try : print(personList[0].name)

You just have an indent problem of your code inside your class.

class Person:
def __init__(self, name, age, sex):
self.name = name
self.age = age
self.sex = sex
#Initialize an instance of the object:
A = Person("John", 34, "Male")
personList = []
personList.append(A)
print(personList)
Just edited the tab before "def __init__" and then pushed each rows, then it's fine.

Try this
personList=personList.append(A)

It works : [<__main__.Person object at 0.7fd4696b8550>]
is a normal output, it says that you are printing an Person object inside a list type.
