QUESTION
I'm relatively new at Python, currently running Python 3.8. I want to take advantage of the many symbols in the DejaVuSans (default font for Matplotlib).
Rather than have users of my program type in the entire unicode sequence (e.g., $\0041$
to plot the letter A) I want them only to record 0041
and I'd build the full code programmatically. It's not working, perhaps a newbie mistake.
The code included is sample code from Matplotlib Basemap, and I'm just changing the parameter to set up the marker. I have a print statement, that shows the variable (mymarker) looks like I've built it correctly, but it fails. If I replace mymarker variable and with marker="$\0041$"
the program runs fine.
ANSWER
Answered 2021-Mar-06 at 05:04You don't pass the quotes in as part of the marker. If you want to use the letter A in mathtext font, you just pass $A$. In code, that would be

Answered 2020-Oct-11 at 22:58As the warning message says - UserWarning: Cannot use bqstorage_client if max_results is set, reverting to fetching data with the tabledata.list endpoint.
So this is still working with the warning and using tabledata api to retrieve data. You just need to point the output to a dataframe object and print it, like below:

Thisselenium.common.exceptions.WebDriverException: Message: '' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
problem arises when I try to run this code. I have downloaded the file from the link and unzipped the it to my download folder like shown: C:\Users\Alexandr\Downloads\chromedriver_win32 . Then I put the path to the executable binary (C:\Users\michael\Downloads\chromedriver_win32) into the Environment Variable "Path".
I found the same thread on StackOverflow and they say I should type chromedriver
in cmd and get something like this tarting ChromeDriver 2.15.322448
, in my case I get "chromedriver" is not inner or outer command
(this was a translation from my native language).
What should I do in this case
ANSWER
Answered 2020-Jul-15 at 06:11In the self.driver = webdriver.Chrome()
, pass the path to the executable as an argument in the parentheses.
For example:
self.driver = webdriver.Chrome('C:/user/Downloads/chromedriver.exe')
QUESTION
I'm a newbie to python and just trying to get my head wrapped around how to get things to run/work in python across different environments. What I mean in this context in regards to environment is this. I'm learning python on my MacBook pro - Catalina 10.15.5. I've installed python using brew install
. I use pyenv
to control versions. Through iTerm I would create virtual environments using virtualenv
and pip install
to install modules, etc.
I'm also using Visual Studio Code and PyCharm to learn and understand these tools as well.
I've reviewed and tried a number of python tutorials in my journey to learning python.
With that said, why is it when using iTerm, if I do a pip install
, the module shows being installed with no errors, but when running the application (FLASK_APP=app.py flask run)
, i'll get this message:

QUESTION
I want to set an environment variable DATABASE_URL
that will be read by my Flask app to connect to the database. I use set DATABASE_URL = '...'
, but I get an error that the variable is not set when I do flask run
. Why isn't this working?
ANSWER
Answered 2018-Oct-21 at 02:04A quick idea to try:
On Windows, use
setx
instead ofset
to modify the system environment variables.setx FLASK_APP = application.py
Start a new command processor to see the variables reflected in your environment (They get set when the shell is initialized).
QUESTION
I am using Flask-Session and recently installed or upgraded to itsdangerous 1.0.0. Now I get the error ImportError: cannot import name 'want_bytes'
. Why is this error happening and how can I fix it?
ANSWER
Answered 2018-Oct-27 at 00:49itsdangerous 1.1.0 contains a temporary fix for this. You can upgrade itsdangerous and continue to use Flask-Session right now. There is no need to pin to itsdangerous==0.24.
itsdangerous 1.0.0 was recently released, removing non-public top-level imports. Flask-Session appears to have been using such an import, from itsdangerous import want_bytes
.
This has been reported to Flask-Session and a fix will hopefully be released eventually.

...ANSWER
Answered 2017-Jan-18 at 01:19See comments - Issue solved by deleting the pyc files.
Python checks to see if the .pyc file's internal timestamp matches the corresponding .py file, and if it does, it loads the .pyc. This can be an issue if you update and you're still using the previously compiled .pyc.
