await sleep(0). The other reason is that forcefully causing a context switch isn't something that seems to be required all that often. Also, if someone wanted to call it schedule(), they could make their own one-line function with that name.
Hi Dave,
I have the following code.a = 'hello!'
b = 'hello!'
a is b
False
id(a)
140428602876016
id(b)
140428602876208
Why does python creates two different string objects in the above example. But when you do not have any special character it does not create two new string objects. >>> a = 'hello'
b = 'hello'
a is b
True
I enjoy watching your talks a lot!
I was inspired by your experiments with generators and coroutines, and came up with a weird idea of making a function behave both like a normal function and like an async coroutine (kinda). So I thought I might share it here - https://github.com/qweeze/maybe_async
It would be super cool if you could share your advice or any kind of feedback.
Went to pick up an item I won at auction today. As there are Covid delays everywhere, I always bring along something to read. Today it was O'reilly's Python Cookbook, which I had on my dash as I approached the gate keeper. Seeing the book he asked if it was any good. Me wearing a mask and he deaf and only able to read lips, hard to do when we are all wearing masks, I gave him my OK hand gesture. He then went on with a fairly long story of the different snake dishes he had eaten in Florida. I listened with interest until he had finished with the "Soupa Serpente" (Snake Soup) he had in Mexico and for him to ask if there were any favorite python recipes in my book. I finally pulled down my mask and mouthed "No, Computers" and mimicked me typing on a keyboard. He replied that he'd search the internet when he got home for recipes and waved me through.
Have a Merry Christmas David and stay well.
Chapter 10 - Execution Environment: "The -m option runs a library module as a script which executes inside the main module prior to the execution of the main script". Really can't get my head around what you meant by 'prior to the execution of main script' at the end of the statement. I've tried looking all over the internet for this but can't get any explanation. Would be grateful if you could explain this to me. Thank in advance
With all this discussion of annotations on Python dev I came up with this syntactically correct way of initializing variables in Python that dynamically applies the correct type at run time:
foo: type(foo := 1)Of course 1 here could be a function call or any other expression you like. It made me think a lot about what exactly are annotations? And how PEP 563 changes them from the arbitrary expressions they are now to more glorified in-line doc strings. Not sure anyone else is thinking much about this, but this is where my brain has been for the last couple of days.
Hello Mr. David M. Beazley, first of all I wish you great health.
I am using your book as study material. I have a simple example of a C program that must be recognized by the parser (using this code as base https://github.com/dabeaz/ply/blob/master/example/classcalc/calc.py).
The example fo C program that must to be recognized is as fallow:
int main(void)
{
int a, b, resultado;
a = 4;
b = 6;
if(a>= 10){
resultado = a - b;
}else{
resultado = a + b;
}
}
Could you help me understand how to embed this into the code in the link I sent you?
Cordially ,

AttributeError: 'Portfolio' object has no attribute 'sort' when I try to run portfolio.sort(key=stock_name) or any kind of sort on the portfolio object. That file is identical to the solutions with the exception of how total_cost is calculated and some line breaks. What could it be?
setLevel() method instead of setting the level property directly, I tried setting the level directly in fileparse.py instead of later in the console. I can print the logger and confirm that it is set to debug level. I've also tried setting it to info level just to see. In no case does it ever print the log.debug messages. Is there something like an environment variable that can prevent lower level log messages from being output? I'm sure I must be doing something silly, but I can't figure out wehat it might be. Even if I copy the solution file for 8.2 fileparse I get the same results.
