Question

In Python

classifying animals as mammals, birds, fish, reptiles, or amphibian. You will classify these animals by asking the user “which of the following features does the animal have: fur, feathers, scales, or skin?” If the user inputs “fur”, “feathers” or “scales”, then you will respond with “mammal”, “bird”, or “fish” respectively. If the user inputs skin, then you will additionally prompt them with “is the skin dry or moist”. If the user enters “dry” then you should return “reptile”, if they enter “moist” then you should return “amphibian”. If at any time the user enters an invalid response, you should print “invalid input” and the program should end. You will use an if/elif/else tree to do these classifications, and your final classification tree will look like this.

Explanation / Answer

Code:

#!/usr/bin/python

def main():

# taking input on the features from user

features = raw_input('which of the following features does the animal have: fur, feathers, scales, or skin? ')

# converting to lowercase so we can compare with lower case values easily

features = features.lower()

# doing a decision making using if

if features == 'fur':

print('The animal is Mammal')

elif features == 'feathers':

print('The animal is bird')

elif features == 'scales':

print('The animal is fish')

elif features == 'skin':

# if features provided is skin we will ask for additional input like the skin dry or moist

stype = raw_input('is the skin dry or moist? ')

stype = stype.lower()

if stype == 'dry':

print('The animal is reptile')

elif stype == 'moist':

print('The animal is amphibian')

# if user enters wrong skin type

else:

print('Wrong skin type provided. Available options are "dry" or "Moist"')

# if user enters wrong feature

else:

print('Wrong features provided. Available options are "fur" "feathers" or "scales"')

if __name__=='__main__':

main()
