Python MetaTrader5 example code TypeError

[mt5attempt]

Hi, could someone explain how to debug the error when running the example code provided from:

• https://www.mql5.com/en/docs/integration/python_metatrader5/mt5symbolstotal_py
• https://www.mql5.com/en/docs/integration/python_metatrader5/mt5symbolsget_py

I've included a screenshot of the exact error message. I've tried using both Python 3.7 and 3.8 versions.

When I run order "order_send" it show error as below :

'NoneType' object has no attribute 'bid'

Is that the same issue? If the order_send function can't be used. That's means no use totally.

Yeah, my Jupyter notebook is on my localhost. I tried specifying the path on initialization as per your suggestion, doesn't solve the issue.

As a temporary solution, would someone kindly provide the list of all 182 Symbols?

I am able to run some of the other example codes with no problems so far, such as copy_rates_from & copy_ticks_from.

Perhaps I didn't make it clear in my original post, but both symbols_get and symbols_total functions are not working for me. They are returning None.
