I am trying to use Computer Modern (i.e. the standard LaTeX font) in my pyplot figures, however, I get the error

the title refers to this problem, I need to get the values under the keyword values of Tkinter TreeView using the method item as in: tree.item(v)['values'][0], v being my selection on the treeview. The method returns an integer, and if the value had zeros befores it just ignores them.

Heres an example of what I mean: I need the value marked in yellow exactly as it is (001) instead of (1). Printing this "tree.item(v)['values'][0]" will say the value it's 1 but the treeview shows the real value 001. How can I get the real value (001)?, Thank you.

How do I ensure that this works correctly for my custom class?

Just some sidenotes, I use XeLaTex to compile my documents while I install the fonts (DejaVu familiy) with the fontspec package and the \setromanfont{DejaVu Serif} command. The classes have the option to switch between the serif and the sans-serif font in the family.

Here is my minimal working example: Consisting of the letter.tex file.
