python string to class

Question

here, i want to take the input and print out the student name....
so, is it possible to convert a string to a class type?

class student:
def __init__(self, name, age, grade):
self.name = name
self.age = age
self.grade = grade

def say_hi(self):
return f"hi, i am {self.name}, i am {self.age} and my grade for last was {self.grade}"

jaff = student('jaff', 18, 75)
bill = student('bill', 17, 95)

student_id = input("who would you like to call up: ")
print(student_id.say_hi())

Answer 1

I don't think there is a way(to my knowledge, I could definitely be wrong), but to solve your problem you could maybe use a dictionary and use the names as the key, the object as the value, then you can search for the name as a key, and then you have the object. It might also make it easier to understand when looking at just the code.

For example:
students = {"jaff" : jaff, "bill" : bill}
print(students[student_id].say_hi())

Hope this helps!

Answer 2

Try this
import ctypes
class Student:
...

st1 = Student(...)
ref = id(st1)
deref=ctypes.cast(ref, ctypes.py_object).value

you could also save the id in class itself with:
self.id = id(self)
