Why doesn't this work?

Question

Recently, I copied a character from the internet (supposed to be '\0' I guess) and made this code using that undisplayable character:

for a in "ab": print(ord(a))

# Where, a string of that character has been included between 'a' and 'b'.

Why does SL show "SyntaxError" whenever I run this code? I had made this code for knowing what exactly that 'undisplayable' character was.

Answer 1

Calvin Thomas ,

the hex editor shows, that there are 46 null characters between a and b. i assume that this is nothing that comes from a regular program, but something that is constructed. using hex editor i was able to do the same thing just by saying insert bytes = 3 value = 00.

for all who are interested, here is the link to the editor:

Calvin Thomas ,

if you can please post the code that creates the issue to playground and link it here?

that would be great - thanks!

I'm very sure that it's a null character between a and b that's causing the problem, but the question is why.

Answer 4

Lothar Thanks for the link, but why does SL show an error when I try to print strings containing null characters?

Answer 5

Runtime Terror Raw strings doesn't seem to make a difference in order for the code to work.

Answer 6

Runtime Terror Doing it in C shows that my clipboard actually contains a null character.

Answer 7

It would work well with while loop instead of for loop.
while "a" in "ab":
print(ord("a"))
break
As,in your case a is not defined!
