For Lab 5 i was given a code which was wrong because it was showing not x and was suppose to see Ok. When starting you should try to get Ok where x said before . If Ok showed in all then i successfully fixed the messed up code here is the code that i used
def cupcakes(count):
if count>=10:
return ‘Number of cupcakes: many’
else:
return ‘Number of cupcakes: %s’ % (count)
def both_ends(s):
n1 = len(s)
if 2>n1:
s22 = ”
else:
n2=n1-2
n3=n1-1
s22 = ‘%s%s%s%s’ %(s[0],s[1],s[n2],s[n3])
return s22
m = s[0]
m1 = s.replace(m, ‘*’)
m2 = s[0] + m1[1:]
return m2
def mix_up(a, b):
d = b[:2] + a[2:]
b = a[:2] + b[2:]
return d + ” ” + b
def match_ends(words):
f = 0
for word in words:
if len(word) >= 2 and word[0] == word[-1]:
f = f + 1
return f
def front_x(words):
v = []
z = []
for w in words:
if w.startswith(‘x’):
v.append(w)
else:
z.append(w)
return sorted(v) + sorted(z)
def test(got, expected):
if got == expected:
prefix = ‘ OK ‘
else:
prefix = ‘ X ‘
print ‘%s got: %s expected: %s’ % (prefix, repr(got), repr(expected))
