pass after a loop is a syntax error???

[Skaperen]

i don't believe this should be an error

Pass is used when some statement is required syntactically. Out of the loop, a function or condition doesn't do anything.
I don't know how to find the source code of pass to see why exactly it happens

I'm guessing that pass is a C macro, perhaps defined like
#define pass (void)0

[micseydel]

It has nothing to do with pass, which needn't be used within any block.

>>> for t in 'abc':
...     print t
... print 'xyz'
  File "<stdin>", line 3
    print 'xyz'
        ^
SyntaxError: invalid syntax

Python's REPL, for whatever reason, just doesn't like it when you try to put code after a block before executing that block.

there is no such define in C.  i'm not using C.  i was using python and testing some code when i ran into this.  i don't actually need to use pass.  i am just bringing it up as "implementation != documentation",

i just ran across another one in datetime but i have yet to test that one thoroughly before posting it.

if these don't work as documented i consider it to be a bug.  i'll let the developers _decide_ if it is a bug in the implementation or a bug in the documentation.

Could you link to that documentation?
