For this project, you will write a test function, test_sscount . test_sscount will automate testing of sscount0 and sscount1 from the second picture.

test_sscount will each have three parameters. The first parameter is f, a function which

will be sscount0 or sscount1. (As you will see in lab this week, Python functions can be

passed as arguments to a function in the same way as other data types.) The second argument is

args, a string with the needle and the haystack strings, separated by one space character.

The final argument is expected_result, an integer which is the expected result of calling

one of the sscount functions for the needle and haystack strings in args.

test_sscount will call f for the needle and haystack string in args, and compare the

result returned by f to the expected result. For each test case, test_sscount should report

whether the actual result matches the expected result, for example:

testing sscount0

Checking sses assesses

its value 2 is correct!

Function test_sscount should return None.

Next, write a main function that calls test_sscount two times once to test sscount0

and once to test sscount1, for a series of test cases. For example,

test_sscount(p34.sscount0, 'sses assesses', 2)

test_sscount(p34.sscount1, 'sses assesses', 2)

main should include calls to test_sscount for at least the following test cases (and expected

results):

'sses assesses', 2

'an trans-Panamanian banana', 6

'needle haystack', 0

'!!! !!!!!', 3

'o pneumonoultramicroscopicsilicovolcanoconiosis', 9

'', 0

'a ', 0

' abc', 0

'a a', 1

Note that at least one of the edge cases will reveal an issue with the posted solutions and/or the

specification for project 3-4. Comment on this in your .py file.

The last line in your .py file should be a call to function main.

I put a picture of what I have so far. I'm struggling really with my for loops so any advice or explanation would be great!

Thanks
