字符串检查和打印中的python字符

Question

This is a noob question asked by a noob. I need to create a function to check whether or no all the character in the string can be found in 'scraps', if true, just print out the whole string once, else, print the error message below. I am sure the real solution is pretty simple but at the moment I feel like I am solving calculus problem with grade school math. please advise. thanks~

def fix_it(scraps, recycled):

The function should be able to produce:

print fix_it('AbCdEfG', 'AhK') ==> "Give me something that's not useless next time."

print fix_it('AbCdEfG', 'CdE') ==> 'CdE'

Answer 1

How about this:

def fix_it(scraps, recycled):
    for i in recycled:
        if i not in scraps:
            return "give me something useful"
    return recycled

print fix_it('AbCdEfG', 'AhK')
print fix_it('AbCdEfG', 'CdE')

output is:

python test.py
give me something useful
CdE
