Installing Visual Studio Code
At first we need to download Visual Studio Code
Setup Python
Please follow all steps from my last post:
https://hive.blog/beempy/@holger80/how-to-setup-a-minimal-python-for-using-beempy-on-windows
There is now a python environment in C:\beem\env or any other path (just replace this path by the correct one). The beem package is installed.
Setup Visual Studio Code
We need to install a extensions for using python:
Open the extensions tab (or press Ctrl + Shift + X)
Enter ms-python.python in the search field and install the python extension
In the next step we setup our python interpreter.
Open the settings tap (or press Strg+,) and enter pythonPath in the search field. Enter the pyth to the python.exe in the Python Path field. In my case, I installed an environment in C:\beem\env, so my path is C:\beem\env\Scripts\python.exe. Replace the path to the python.exe with the one on your PC.
It is also possible to edit the settings.json (by pressing Edit in settings.json in the Settings tab:)
"python.pythonPath": "C:\\beem\\env\\Scripts\\python.exe"
Replace the path to the python.exe with the one on your PC.
There may be a prompt, if we want to install the pylint package:
In my case, installation failed with:
and I installed it manually by opening the powershell and entering the following commands:
cd C:\beem
.\env\Scripts\activate
pip install pylint
Debugging a beem python script
Create a new file (Ctrl+N) and copy the following into it:
from beem import Steem
from beem.account import Account
if __name__ == '__main__':
stm = Steem()
acc = Account("holger80", steem_instance=stm)
print("My vote power: " + acc.vp)
Store the file as py_test.py.
We will now run the script without debugger (Ctrl+F5 or using the menu: Debug/Start without Debugger). The script crashes with a error message:
print("My vote power: " + acc.vp)
TypeError: can only concatenate str (not "float") to str
Now we will investigate. We enter a breakpoint at line 7 by pressing left to the line number.
We start the script with Debugging (F5) and click on the DEBUG CONSOLE:
Now we can investigate the error in the debug console:
At first we check acc.vp by writing it into the terminal:
So this works, now we enter the string inside the print command:
"My vote power: " + acc.vp
The problem is that the + does not work with a Float and a String. We try to fix it in the debug console by entering:
"My vote power: %.2f" % acc.vp
This works and we can fix the script.
We replace the line with
print("My vote power: %.2f" % acc.vp)
save the script and press restart:
It stops at the breakpoint and we can press F5 for continue.
Now everything runs through!
although all this coding stuff is way above me, I value tutorial type post being published on steem. Nice work

Oh yes, i did it :-) Thanks for getting this first step done!!!
I was looking like crazy to find your steemmonster api. The thing is that when i visit github and i click on your name, this steemmonster api does not appear in your projects. I found it now but now i am looking for something which you call beem.api, baby steps are small but hey, really thank you, i am already proud to be standing now.
