2. After the except block
3. At the end of every try block
4. When an error code stops the else block
9. Test-driven development requires that developers:

2. Know how to use DevOps tools for automated testing
3. Create a simple test that fails and then write code that allows the
test to succeed
4. Completely unnecessary in an Agile development shop
10. What is the difference between a unit test and an

FILE INPUT AND OUTPUT
Pulling data from a file in Python is very straightforward.
To extract data from a text file, you can use native
Python capabilities. Binary files, on the other hand, need
to be processed by some module or another external
program before it is possible to extract the data from
them. The vast majority of your needs will be addressed
through text files, so that is what this section focuses on.
From Python’s perspective, a text file can be thought of
as a sequence of lines. Each line, as it is read in to
Python, is typically 79 characters long (per PEP 8
