You should add a more intelligent filename generator, filter out mail:
urls and possibly others and add
expressions, so this helps. We don't
have to emulate booleans and conditions with weird lambda expressions.
In Python's lambda expressions you can not use statements, only
expressions, so without conditional expressiosn Python's booleans
wouldn't be very useful.
The rema

h the same problem posted a smaller, more complete example here:

Then you should give us real code (a minimal example) that we can try. You use
myFunction in your example that isn't defined in your code. And by the way, why
don't you close f just after reading? Or even better, use
therefore
_WorldProper is not defined.
from import * is considered bad practice anyway. It is better just to import
the things you need.
from pykkar import World, Pykkar, _WorldProper
I have looked a bit in this pykkar.py and I think it is badly structured for
extension. The three classes

But it only works if the external C library has been written to release
the GIL around the long computations. If not, then the OP could try to
write a wrapper around them that does th
more help. But you can do everything you want with 2.x, I think.

File locking is generally the best solution for this kind of problems, unless
you can make use of OS level semaphores.

way without the risk of race conditions. Maybe I have to find out.

I would guess the difference to be caused by DNS. Maybe the DNS configuration
on the RPi is not optimal.

Lisp and scheme use
ll due respect, Mark, your remarks are rubbish. Nobody talked about
parsing input with binary switches except you. I answered that 40 years ago I
wrote a parser generator that generated a parser for Algol 68 (and another one
for Algol 60 I should have added). And all this was using punched cards.
ors that translated into pure C
code, which was then compiled with a C compiler. The resulting intermediate C
code would be an object-oriented program in C. IIRC, the C code was reasonably
clear, not really convoluted, so you would have been able to write it yourself.

Something like:
plt.plot(20,40, 'bo')
plt.annotate('B', (20,40), xytex

Tcl 8.5

A language specification in BNF is just syntax. It doesn't say anything
about semantics. So how could this be used to produce executable C code
for a program? BNF is used to produce parsers. But a parser isn't
sufficient.

kens relate to each other.
Syntax is grammar. Tokens are part of the grammar (but often specified
separately with a different grammar, usually regular expressions, which is a
subset of BNF).
So are you just confused or are you trollong?

That's not English. Do you mean "parsed"?
But context-sentitive grammars cannot be specified by BNF.
