Question

#Python

3. Using a for loop, write a function called farmAnimals() that accepts a list of animals on a farm, identifies the typical farm animals, and returns a list of these typical farm animals on the farm without duplicates. For this function, your typical farm animals are cow, chicken, goat, pig, and sheep. Sample output;

>>> animalsOnFarm = ['cow', 'cow', 'cow', 'dog', 'cat', 'bird']

>>> farmAnimals(animalsOnFarm)

['cow']

>>> animalsOnFarm = ['pig', 'sheep', 'cow', 'cow', 'cow', 'dog', 'cat', 'bird']

>>> farmAnimals(animalsOnFarm)

['pig', 'sheep', 'cow']

>>>

Answer 1

I have written the program using PYTHON PROGRAMMING LANGUAGE.

OUTPUT :

CODE :

#function definition for farmAnimals

def farmAnimals(animalsOnFarm):

farmanimals = ['cow','chicken','goat','pig','sheep']

output = []#declared the output variable

if('list' in str(type(animalsOnFarm)) and len(animalsOnFarm)!=0):

#iterating over the animalsOnFarm list

for animal in animalsOnFarm:

if(animal not in output and animal in farmanimals):

#adding to the output variable if animal is not existing in it before

output.append(animal)

else:

continue

return output#return output

else:

#in case if the length of input list is zero

return "Invalid Input!!!"

#defind the input list

input_list = ['cow', 'cow', 'cow', 'dog', 'cat', 'bird']

#printing the input list and output list on the console

print("\nINPUT :\n"+str(input_list))

print("\nOUTPUT : \n"+str(farmAnimals(input_list)))
