(Get the code!)
I ended up implementing this in:
https:/
(It looks like I just changed `pieces = line.split(None, 4)` to `pieces = line.rstrip(
An example use is:
https:/
And as early as Python 2.7.15, at least, generator functions don't execute *any* statements until the first attempt to dereference them:
```
>>> def F():
... print "I'm running!"
... with open('/
... print "I've opened zone.tab!"
... for line in fobj:
... print 'I read %r!' % line
... yield line
... print "I'm done reading!"
... print "I'm done executing!"
...
>>> ZONE_TAB = F()
>>> for _ in ZONE_TAB: pass
...
I'm running!
I've opened zone.tab!
I read '# tzdb timezone descriptions (deprecated version)\n'!
I read '#\n'!
[...]
I read 'ZW\t-1750+
I'm done reading!
I'm done executing!
```
Specifically:
```
>>> ZONE_TAB = F()
>>> ZONE_TAB.next()
I'm running!
I've opened zone.tab!
I read '# tzdb timezone descriptions (deprecated version)\n'!
'# tzdb timezone descriptions (deprecated version)\n'
>>> ZONE_TAB.next()
I read '#\n'!
'#\n'
>>>
```
This seems to be intended behavior; from https:/
"When a generator function is called, [...] no code in the body of the function is executed. Instead a generator-iterator object is returned [...]
Each time the .next() method of a generator-iterator is invoked, the code in the body of the generator-function is executed until a yield or return statement (see below) is encountered, or until the end of the body is reached.
If a yield statement is encountered, the state of the function is frozen, and the value of expression_list is returned to .next()'s caller."
I actually just popped in and need to run again, but if that still sounds alright I'd be happy to put together an updated patch without "with".
