If you cut and paste probably the misaligned indentation is the least problem. Cut and paste should be avoided if it's not done during a refactoring (so actual moving of code for better design).
Beginners usually think Python strong indentation is a weakness of the language. I actually find C++ freedom being more error prone:
if (a < b);
a = b
It's a not very frequent bug, but when it happens it takes you hours to spot. ;)
If you ran the code through gofmt, it would remove the () around the cond for you. I code go in SublimeText with GoSublime. On every save it runs the file through gofmt and reformats it for me. Keeps my code looking pretty with very little effort.
