Bug-Fixing Exercise 1

The program depicted below consists of two Python files. The program tries to count and print out the number of periods in the "Trees are good. Grass is green." . However, running the main.py file returns an error. Please fix the error.

main.py:

import functions

nr_of_periods = count("Trees are good. Grass is green.")
print(nr_of_periods)

functions.py:

def count(phrase):
    return phrase.count('.')

Solution

Bug-Fixing Exercise 2

The same program as in exercise 1 now is throwing yet another error. Hunt the error down and fix it.

main.py:

import functions.py

nr_of_periods = functions.count("Trees are good. Grass is green.")
print(nr_of_periods)

functions.py:

def count(phrase):
    return phrase.count('.')

Solution

Bug-Fixing Exercise 3

There is another error in the same program. Please fix the error.

main.py:

from functions import count

nr_of_periods = functions.count("Trees are good. Grass is green.")
print(nr_of_periods)

functions.py:

def count(phrase):
    return phrase.count('.')
