Python gotcha

This Seemingly innocuous indentation error in python was annoying me.

Problem invoking WLST - Traceback (innermost last):
(no code object) at line 0
File "C:\apps\installWls.py", line 249
toDeploy = sys.argv[3]
SyntaxError: inconsistent dedent

The issue was some copy and paste code I took from the internet.

It was indented using spaces, whereas I was using tabs.

Replacing the space indentation with tabs fixed the issue (but its not obvious uinless you set your editor to display non visible characters.
