Explanation / Answer

Here are the solutions for the first 4 questions explained.

favs = ['Leia', 'R2-D2', 'Solo', 'Chewbacca']
vowels = 'aeiou'
for vowel in vowels:   #For each character in vowels.
   for fav in favs:   #For each string in favs list.
       if vowel in fav:   #If the current vowel is in the current fav
           continue       #Go ahead.
       else:               #If the current vowel is not in current fav
           print fav[0],   #Print the first character of current fav
           break           #Come out of the inner loop.
'''
For 'a':
   'Leia' has 'a'
   'R2-D2' doesn't have 'a', so will print 'R'
For 'e':
   'Leia' has 'e'
   'R2-D2' doesn't have 'e', so will print 'R'
For 'i':
   'Leia' has 'i'
   'R2-D2' doesn't have 'i', so will print 'R'  
For 'o':
   'Leia' doesn't have 'o', so will print 'L'
For 'u':
   'Leia' doesn't have 'u', so will print 'L'  
So, finally, the output is: d. RRRLL'''

pairs = {'':'empty', 2:'prime', 1:{'polio', 'smallpox'}}
print pairs[1][1]  
#This leads to an error, but is not TypeError.
#So, the answer is e. non of the above.

def dictTest(aType, aDict):
   if aType in aDict:   #If the key is in aDict.
       return aType   #Return key.
   else:               #If not.
       for v in aDict.values():   #For each values in aDict.
           if aType in v:           #If the aType is value.
               return v           #Return value.
types = {string:'string', num:0, tuple:('a', 'ok')}   #Here the string in the key will lead to error.
   #So, the answer is: d. NameError: name 'string' is not defined.
print dictTest('string', types)  

boolExprs = {True and False, not True, True or False, True and not False}   #This leads to values {False, False, True, True}  
tCount = 0          
for expr in boolExprs:
   if expr == True:   #First expression is False.
       tCount = 2 * tCount + 1
   else:      
       break       #So will come out of the loop.
print tCount       #So, the value of tCount is not modified.
#The answer is 0, i.e., e. none of the above.
