Feb 7-9

Alright on Monday I wasn't able to get on due to computer issues. This continued to at least half of the class on Tuesday. So today i'll continue on Chapter 5 questions #1.
#1: def compare(a, b)
"""
>>> compare(5, 4)
1
>>> compare(7, 7)
0
>>> compare(2, 3)
-1
>>> compare(42, 1)
1
"""


"""
>>>compare(a > b)
1
>>>compare(a == b)
0
>>>compare(a < b)
-1
"""


if __name__== ' __main__':
import doctest
doctest.testmod()
This program really got me for awhile. When I first started out I had changed the def compare(a, b) to def compare( a > b). Which was giving me an error saying that > was an invalid syntax. But the spur of the moment thought make me think to instead add a > b, a == b, and a < b, to next to the >>>compare. After one try i got this right away. This was a pretty easy program to make after I found out exactly what I had to do.
#2: def hypotenuse(a, b): """ >>> hypotenuse(3, 4) 5.0 >>> hypotenuse(12, 5) 13.0 >>> hypotenuse(7, 24) 25.0 >>> hypotenuse(9, 12) 15.0 """ if __name__== '__main__': import doctest doctest.testmod()
Which I then got an output of:

*****************************************************************************

File "hypotenuse.py", line 7, in __main__.hypotenuse

Failed example:

hypotenuse(7, 24)

Expected:

25.0

Got nothing

Failed example:

***Test Failed*** 4 failures.

#3: def slope(x1, y1, x2, y2): """ >>> slope(5, 3, 4, 2) 1.0 >>> slope(1, 2, 3, 2) 0.0 >>> slope(1, 2, 3, 3) 0.5 >>> slope(2, 4, 1, 2) 2.0 """ if __name__== '__main__': import doctest doctest.testmod()
 

With an end result of:
