What is wrong with the following Python code?

Could any one help me to debug the following python code?

code is shown here:

#!/usr/bin/python
# Filename: using_tuple.py


zoo = ('python', 'elephant', 'penguin') # remember the parentheses are optional
print('Number of animals in the zoo is', len(zoo))

new_zoo = ('monkey', 'camel')
print('Number of cages in the new zoo is', len(new_zoo))
print('All animals in new zoo are', new_zoo)
print('Animals brought from old zoo are', new_zoo[2])
print('Last animal brought from old zoo is', new_zoo[2][2])
print('Number of animals in the new zoo is', len(new_zoo)-1+len(new_zoo[2]))

The variable new_zoo has two elements and the number of elements starts from zero

In this line: `print('Last animal brought from old zoo is', new_zoo[2][2])'

new_zoo[2][2] is invalid in your current code for 2 reasons: 1. Arrays are 0-indexed. new_zoo[2] refers to the 3rd element, not the 2nd. 2. Also, you will just be printing a character (specifically the 3rd character) of that zoo animal.

You forgot to add the old zoo to the new zoo.

Indexing in programming languages usually starts from zero, not one. The length maybe 2, but the second element is with the index 1.

Where do you combine old and new zoo?

Possibilities:

>>> new_zoo = ('monkey', 'camel', zoo)
>>> new_zoo
('monkey', 'camel', ('python', 'elephant', 'penguin'))
>>> new_zoo = ('monkey', 'camel') + zoo
>>> new_zoo
('monkey', 'camel', 'python', 'elephant', 'penguin')
