Comment

It is imperative to use class variables properly since they are shared by all the class objects and can be modified using any one of them. Below is an example of wrongful use of class variables:

class Player:
    formerTeams = []  # class variables
    teamName = 'Liverpool'
    def __init__(self, name):
        self.name = name  # creating instance variables


p1 = Player('Mark')
p2 = Player('Steve')

p1 = Player('Mark')
p1.formerTeams.append('Barcelona') # wrong use of class variable
p2 = Player('Steve')
p2.formerTeams.append('Chelsea') # wrong use of class variable

print("Name:", p1.name)
print("Team Name:", p1.teamName)
print(p1.formerTeams)
print("Name:", p2.name)
print("Team Name:", p2.teamName)
print(p2.formerTeams)
