PROBLEM #1
heights = {"Mount Everest": 8848, "Mount Cook": 3754, "K2": 8611,
"Ben Nevis": 1344, "Hekla": 1488}
Since you already have a dict of heights why do you pass one in to the
function each time? Why not just pass this one in? Or use it as a global?
def mountain_height(heights, mountain):
'''Return the height of the mountain.
If the mountain isn't in the dictionary, the
height returned should be -1.
The search should ignore any spaces before or after the name.
>>> mountain_height({'K2':8611, 'Hekla':1488}, "K2")
8611
>>> mountain_height({'K2':8611, 'Hekla':1488}, "Hekla ")
1488
>>> mountain_height({'K2':8611, 'Hekla':1488}, "Port Hills")
-1
'''
if mountain.strip() in heights:
return heights[mountain.strip()]
else:
return -1
The last 4 lines can be replaced by heights.get(.....)
Check the dict documentation.
print(mountain_height({'K2':8611, 'Hekla':1488}, "K2"))
#8611
print( mountain_height(heights, 'K2') )
PROBLEM #2
def is_up_down(values):
'''Return True if values is an up-down-sequence, otherwise
return False.
This is more complex and I'm about to get busy, I might post a reply
if I get time later and nobody else has...
