how to iterate list of objects

Question

I have a list of objects. I would like to check some string if that string exists as a field value any object in the list. for example,

class Ani:
    name = ''
    def __init__(self, name):
        self.name = name

    def getName(self):
        return self.name


animal1 = Ani('alica')
animal2 = Ani('rex')
animal3 = Ani('bobik')
animal4 = Ani('dobik')
animal5 = Ani('sobik')

a = [animal1, animal2, animal3,animal4,animal5]

my problem to write a code in order to see if there is an object with given name. for example "chip".

You can iterate over the array of objects, and check with each object's getName function.

class Ani:
    name = ''
    def __init__(self, name):
        self.name = name

    def getName(self):
        return self.name


animal1 = Ani('alica')
animal2 = Ani('rex')
animal3 = Ani('bobik')
animal4 = Ani('dobik')
animal5 = Ani('sobik')

animals = [animal1, animal2, animal3,animal4,animal5]

searched_animal = 'rex'

for animal in animals:
  if animal.getName() == searched_animal:
    print('Found')
    break

You can use any plus a comprehension:

any(animal.getName() == "chip" for animal in animals)

You can use the getName method present in Ani class for this program

class Ani:
    name = ''
    def __init__(self, name):
        self.name = name

    def getName(self):
        return self.name


animal1 = Ani('alica')
animal2 = Ani('rex')
animal3 = Ani('bobik')
animal4 = Ani('dobik')
animal5 = Ani('sobik')

animals = [animal1, animal2, animal3,animal4,animal5]

key = 'chip'

flag=0
for animal in animals:
    if animal.getName() == key:
        print('Found')
        flag=1
        break

if flag==0:
    print("Not Found")

Iterating a list containing anything is quite simple really. Like so:

animal_to_find = "someAnimal"
for animal in animals:
  if animal.getName() == animal_to_find:
    print("Found a match for: " + animal)
