>The following are the code I currently have and the error produced when I attempt to run it. I have tried everything I can think of to resolve the issue, and I have also run the code through a checker, which has said that there are no mistakes. I have also shown a friend who is a programmer, and he cannot find a problem with it. The teacher doesn't actually know the solution to the problem so I was wondering if someone could point me in the right direction to get this working please?

	Really -- neither the instructor nor a programmer can find any problems
in the code sample? I count ten problems minimum, just scanning the code.

	A checker won't find anything since every statement is valid Python
syntax -- it just doesn't do what you expect.

	You declare "second" as a function taking one argument, but you never
use the argument (hint: (int) is not a declaration of a return type).	#1

	You invoke strftime() [in default: use current time mode], but pass it
a format that is not defined in the documentation (or wasn't in Python 2.7
which I'm still running).	#2
 %s (lowercase) formats the seconds field of the time of day. And worst,
since you don't return the result, it just gets thrown away.	#3

	Good thing you never call your second() function.	#I won't count that

>start = input('Press enter when you are ready to start')
>time1 = time.strftime("%S")
>
	This time you save the string form of the seconds of the time-of-day

>then = time.time()
>
	And here you actually get numerical clock value. Of course, a few
milliseconds may have passed while the previous statement was processed, so
this time will be different from the time used in strftime().

>end = input('Press enter when you think 10 seconds has passed')
>time2 = time.strftime("%S")
>
	Same comment as under "start"

>def totaltime(int):
>    (time2-time1)
>
	Again you define a function with an input argument which is not used.
#4

	time2 and time1 are STRINGS; you can not subtract them from each other.
#5
They are also only the second field from a time-of-day which means it is
possible that they crossed over a minute boundary:

	TOD1	11:59:59		time1	59
	TOD2	12:00:09		time2	9

	time2 - time1		-50			#6

	Again you do not return the value computed in totaltime, so it is not
available for other uses later.		#7

>if totaltime == '10':

	As explained by others, you aren't calling totaltime, you are only
referencing the function object itself.		#8

	You are also expecting it to return a character string rather than a
number, since it is a character string you are comparing against.

>    print ('YOU ACTUALLY DID IT')
>    
>if totaltime < 10:

	This time you are comparing against an integer value...	Which is it
supposed to be		#9 (either the character is wrong, or the integer is
wrong)

>    print ('Haha you took too long! Your result was:', totaltime,'seconds')
>
	If the "player" took LESS THAN 10 seconds you print that they too too
long.		#10

>if totaltime > 10:
>    print('Too early TRY AGAIN! Your result was:', totaltime, 'seconds')
>
	And if they took more than 10 seconds you say they were too early. #not
counted

	You also attempt to call totaltime 5 times in that section of code,
even though the result won't change.		#not counted

Press [enter] to start timing
Press [enter] when you believe 10 seconds have passed
You were too slow! Your time was 12 seconds

Press [enter] to start timing
Press [enter] when you believe 10 seconds have passed
You were too fast! Your time was 8 seconds
