parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

I'm using tqdm twice in my script, and the first time it works fine but the second time it only updates after 14 iterations. It's the same if I remove all other print statements. Any idea what might be going wrong?
Program:
...ANSWER
Answered 2021-Mar-23 at 21:25tqdm doesn't, by default, show every single update if the updates happen fast; by default it only updates 10 times per second. You can set the miniters
parameter to 1
if you must have the output update on every iteration.
The default is miniters=None
, which means it'll dynamically adjust the iteration count based on mininterval
, which is set to 0.1
seconds.
You are also using print()
, which replaces the bar output. Don't do that, updates will be overwritten and you get very messy output.
The tqdm
class has a dedicated tqdm.write()
method, use that instead:

I'm writing my first test in rails and I have a method which checks if the name passed through the animal object is valid. (Will return the name if valid or nil
if not)
animal_verifier.rb

is never initialized in your test, so it's nil
, that's why you see the error undefined method ... for nil:NilClass
. You should create an object under test first and then call methods on that.
When you call object.send("Beluga")
, a message "Beluga" is sent to the object
and it tries to invoke a method named Beluga
. If it fails to find it in default case it raises an error of undefined method Beluga
Your test should look more like:

So I managed to get asyncio / the Google CSE API to work together.... When I run my code on PyCharm, I am able to print my results out. However, at the very end of the printed stuff is the error "TypeError: 'NoneType' object is not callable".
I suspect it has something to do with my list and maybe the loop trying to search for another term even though I'm at the end of the list...
Also.. this is my first question post so feel free to offer suggestions on how to ask questions better as well
Thoughts?
