2 questions about spyder

[Joe Babb]

I'm a new user to spyder and am learning Python.  I've lots of experience coding in C++.

I'd like to view data in the variable explorer as hex values.  But after opening a file to read binary, the values display as text if it can be decoded that way or a blank if not.  Is there a way to get the hex values displayed in the variable explorer?

I'm having trouble updating spyder.  Now running 4.1.5 which works fine.  It keeps asking me to update to 4.2.0.  I tried the "conda update spyder" but that did not work.
