class arguements

[astral_travel]

yea i'm reading it now (i read the first article, now i'm in the class inheritance article),
and there's something that i see repeats itself always when defining a class:

in this code:

class AnyEmployee(object):
    
   def __init__(self, grade, title, first, last, location, phone, pay):
      self.grade = grade
      self.title = title
      self.name = (last, first)
      self.location = location
      self.phone = phone
      self.pay = pay
       
   def contact_info(self):
      text = ', '.join(self.name) + ' ('
      if self.location:
         text += self.location + ', '
      text += self.phone + ')'
      return text
    
   def weekly_pay(self, hours = 0):
      if self.grade == 'Manager':
         return round(self.pay / 52, 2)
      else:
         week = self.pay * hours
         if hours > 40:
            week += self.pay * 0.5 * (hours - 40)
         return week

how do you call lines 4 to 9 ? (like, is there a term for it ?)
