tcolorbox in a sublevel of enumerate containing verbatim

I would like the codepy box defined below to start either:

• to a new line,
• or its width be reduced so that it does not overlap with number 1.1]
  How to do this ?

When tcolorbox contains a verbatim environment, the box covers the number.
