Python identation error?

Wictorian · July 25, 2021

so this line causes an error

if count< len(y)-3:
            flist.append((int(y[dacount])*int(y[dacount+1])*int(y[dacount+2])*int(y[dacount+3]))
print(flist.sorted())

Full code: (I think this is unrelated but here it is anyways.) (It is my solution for Project Euler problem 11)

The indentation posted in the spoiler looks fine.

This line, above, isn't proper, and is missing a space right after count.

It should look like the following:

There are multiple problems here:

`dacount` is not defined

the line

flist.append((int(y[dacount])*int(y[dacount+1])*int(y[dacount+2])*int(y[dacount+3]))

has an unnecessary open bracket and should be

flist.append(int(y[dacount])*int(y[dacount+1])*int(y[dacount+2])*int(y[dacount+3]))

If it looks fine visually IndentationErrors are often mixing spaces and tabs. Although I believe it should throw an inconsistent indentation error then as well. In any case, just try reindenting it.

I updated the code and it works but it gives the wrong result.
