Correct Answers A+
Which syntax will import the module named helpers from the package named lessons? -
Answer✔from lessons import helpers
When an import statement imports another module for the first time, what happens at a high
level? - Answer✔The entire imported module is evaluated
Suppose a module named foo is imported from a packaged named bar. In the scope (frame)
where foo is imported, foo is bound to the globals frame of the module foo after the entire
module evaluates. - Answer✔True
In what scenario is __name__ not assigned "__main__"? - Answer✔When a python module is
being imported into another module.
In what scenario is __name__ assigned "__main__"? - Answer✔When a python module is being
run as a program such as python -m lessons.imports
Which syntax will import the function named powerful from the module named helpers
contained in the package named lessons? - Answer✔from lessons.helpers import powerful
Which syntax will alias the helpers module imported from the lessons package with a local name
of hp? - Answer✔from lessons import helpers as hp
You can access global variables in other modules via importing the module or the variable
directly - Answer✔false
The word "unit" in "unit testing" refers to: - Answer✔A unit of functionality
One benefit of unit testing is that once you have written your test functions it is less cumbersome
to rerun multiple tests than testing manually in the REPL. - Answer✔True
One benefit of unit testing is that when a test fails the output is more helpful in showing you
where exactly a test case is failing. - Answer✔True
The assert keyword should be followed by a boolean expression. This expression should evaluate
to True if the unit of functionality you are testing is working correctly, as expected. -
Answer✔True
When using pytest, a popular unit testing framework, what convention must the file name of the
file containing your test functions follow? - Answer✔Ends with _test.py

When using pytest, what convention must the names of the test functions inside the test file
follow in order to be discovered as test cases? - Answer✔begins with test_
Suppose your test subject(s) (the function(s) you are working on) are contained in a directory
named lessons and a file named subjects.py. Imagine the function you are working on is named
example_function. How would you import the function into your tests file? - Answer✔from
lessons.subjects import example_function
Suppose your test functions are contained in a directory named lessons and a file named
subjects_test.py. How would you run pytest from the terminal? - Answer✔python -m pytest
lessons/subjects_test.py
You should write many individual tests that probe specific, individual use and edge cases rather
than very few complex tests that probe many use/edge cases at the same time. - Answer✔True
The same variable name cannot have different meanings in different contexts within a single
Python program. - Answer✔false
In an environment diagram, a function call frame is its own context for the names of parameters
and variables defined within the function. - Answer✔True
What would be the printed result of evaluating the following Python code listing?
x: int = 0
def f() -> None:
x: int = 1
f()
print (x) - Answer✔0
In an environment diagram for the example above, the function call to f results in a new frame.
That call's evaluation would result in the frame having a variable named x defined in it whose
value is 1. - Answer✔True
The following subquestions regard the code listing below:
x: int = 1
def f(y: int) -> int:
return x + y
