I Want My Ttk.treeview To Have Alternating Colours

I want my ttl.treeview table to have an alternating pattern of colours and I tried to add tags and make the background of each odd row distinct by using the tag_configure method, b

Solution 1:

-what version of python are you using (python -V) in cmd

-the last version(3.7) of python seems like it has bugs to color tags

-if your using the last version just install python 3.6

-one of your tags doesn't have a color

self.Tabla.tag_configure("impar", background="#ff008c")
