I don't know why you use else when you have a code like this.
At first, I thought the After executing it, if you erase When should the else statement would be executed if the for statement didn't even start (if Falsebreak, else will be executed, and if break is not cleared, else will not be executed.for-else statement be used?
When you use a for-else statement, you usually say, "Look for an item in an item in your earlobe. But if you can't find anything, it means...
found_obj = None
for obj in objects:
if obj.key == search_key:
found_obj = obj
If break #item is found, break - else statement will not be executed
else:
print 'No object found.' #Running only if item is not found
If you encapsulate it and write it as a function,
def find_obj(search_key):
for obj in objects:
if obj.key == search_key:
return obj
Or if you use the built-in list,
matching_objs = [o for o in objects if o.key == search_key]
if matching_objs:
print 'Found', matching_objs[0]
else:
print 'No object found.'
