October 25, 2021 Python

In this post, you will learn how to work with init so that you can use that same knowledge and thus evolve.

init is basically a constructor and its function is to initialize everything that is necessary when creating a certain object.

class Person:
  def __init__(self, firstName, lastName, age):
    self.firstName = firstName
    self.lastName = lastName
    self.age = age

  def information(self):
    print('Name:', self.firstName, self.lastName)
    print('Age:', self.age)

  def checkEntrance(self):
    if self.age >= 18:
      print('This person can enter the place because he is of legal age.')
    else:
      print('This person cannot enter the site because he is a minor.')

pessoa1 = Person('Nelson', 'Silva', 25)
pessoa2 = Person('Larissa', 'Fernandes', 17)

pessoa1.information()
pessoa1.checkEntrance()

'''
  Name: Nelson Silva
  Age: 25
  This person can enter the place because he is of legal age.
'''

pessoa2.information()
pessoa2.checkEntrance()

'''
  Name: Larissa Fernandes
  Age: 17
  This person cannot enter the site because he is a minor.
