Find the largest odd number (follow-up code)
Be careful of changing back and forth from ' and ". I can see that you probably used the double quotes just so you could include an apostrophe, but I think it's best to stay consistent and use them throughout since you never need to print any "'s later in the program.

print "You'll be asked to enter 10 integers."
print "The program will look for odd numbers, if any."


Also, you don't need to keep the list of odd_numbers if all you want is the highest one. So you could just directly get the max value:

max_value = max([item for item in numbers_entered if item % 2 == 1])


And this way, you don't even need to build a list. You can instead pass something called a generator expression directly to max. It's like a list comprehension, but it doesn't create a full list. It can be used in both for loops and functions that lake lists, like max does.

However, this would raise a ValueError if you had no odd numbers in the list, as max can't take an empty sequence. But you could just use this as your test instead of if odd_numbers. 

try: 
    max_value = max(item for item in numbers_entered if item % 2 == 1)
    print "The largest odd number entered was {}.".format(max_value)
except ValueError:
    print "No odd number was entered."
