[Python] IntelliSense in Visual Studio Code doesn't work with some object ( in Python)

I'm new to VSCode. I noticed that code completion (intellisence) doesn't work with some object. I searched on the web but I didn't find an answer. My problem is that with some object intellisens works fine, like on the picture below With other object I don't get any hint.



What is surprising in Intractive window everything is ok

from xml.dom import minidom


doc = minidom.parse("alarmBlocks.xml")
doc. # there is no hint

import numpy as np

p = np.arange(1,14,0.1)
p. # here I can see all the methods


Could you please give me some hints where I should look for solution of this problem? Thank you in advance.

I reinstaled Python extension but without results. Settings in launch.json are listed below

}
