Question

InPython,

Create a list of strings, don’t ask from the user, and return a list with the strings in sorted order, except group all the strings that begin with 'x' first.

e.g. ['mix', 'xyz', 'apple', 'xanadu', 'aardvark'] yields

['xanadu', 'xyz', 'aardvark', 'apple', 'mix']

# Hint: this can be done by making 2 lists and sorting each of them before combining them.

Answer 1

list1 = ['mix', 'xyz', 'apple', 'xanadu', 'aardvark']
print list1
list2 = []
list3 = []
for i in range(len(list1)):
if list1[i].startswith('x'):
list2.append( list1[i])
else:
list3.append( list1[i])
list3.sort()
list2.sort()   
list1 = []
list1.extend(list2)
list1.extend(list3)

print list1

Output:

sh-4.3$ python main.py                                                                                                                                                                                                                                 

['mix', 'xyz', 'apple', 'xanadu', 'aardvark']                                                                                                                                                                                                          

['xanadu', 'xyz', 'aardvark', 'apple', 'mix']
