Answer 1

I can give you the entire program at once and kindly divide it according to your need.

Program:

class Window:
def __init__(self, name, age, gender):
self.name = name
self.age = age
self.__gender = gender

def getValues(self):
print(self.name, self.age, self.__gender)

def setValues(self, name, age, gender):
self.name = name
self.age = age
self.__gender = gender

sample = Window('aaa', 19, 'M')
sample.getValues()
sample.setValues('bbb', 20, 'F')
sample.getValues()

These is the first file which contains the Window Class with accessor and mutator (i.e., getValues and setValues function).

Save this in the desired folder, in my case i saved it in the same workspace in the folder names PythonFiles.

Program 2:

from Chegg import Window
p1 = Window('ccc', 21, 'M')
print(p1.name)
print(p1.age)

You can change the import statement to the loaction from you need to import the file for further use.

Hope this helps!!!
