Others have already noted that "verify" is a very strong aim.

There are different kinds of errors.

Some can be avoided by using an integrated development environment
(e.g. misspellings, type mismatches, ...).

Some can be found via tests.
Look at Python's "unittest" package for learn how to write tests.
"unittest.mock" can help you to mockup hardware you do not yet have.
