Word Search in Python
Create a program to solve a word search puzzle.
exercism fetch python word-search
In word search puzzles you get a square of letters and have to find specific words in them.

There are several programming languages hidden in the above square.
Words can be hidden in all kinds of directions: left-to-right, right-to-left, vertical and diagonal.
Given a puzzle and a list of words return the location of the first and last letter of each word.
Sometimes it is necessary to raise an exception. When you do this, you should include a meaningful error message to indicate what the source of the error is. This makes your code more readable and helps significantly with debugging. Not every exercise will require you to raise an exception, but for those that do, the tests will only pass if you include a message.
To raise a message with an exception, just write it as an argument to the exception type. For example, instead of
raise Exception, you should write:
raise Exception("Meaningful message indicating the source of the error")
Running the tests
To run the tests, run the appropriate command below (why they are different):
- Python 2.7:
- Python 3.3+:
Alternatively, you can tell Python to run the pytest module (allowing the same command to be used regardless of Python version):
python -m pytest word_search_test.py
-v: enable verbose output
-x: stop running tests on first failure
--ff: run failures from previous test before running other test cases
For other options, see
python -m pytest -h
