Sqlite3, OperationalError: unable to open database file

Question

Question: Why can\'t I open the database?

Info: I\'m working on a project using sqlite3 database. I wrote a test program that runs and passes it t

In my case, the solution was to use an absolute path, to find an existing file:

import os.path
filepath = os.path.abspath(filepath)
# Leave this out if the file doesn't exist yet
assert os.path.exists(filepath), "The file doesn't exist"
conn = sqlite3.connect(filepath)

I don't know why this fix works: the path only contained ASCII characters and no spaces. Still it made the difference.

For reference: Windows 7, Python 3.6.5 (64-bit).

I was not able to reproduce the issue on another machine (also Windows 7, Python 3.6.4 64-bit), so I have no idea why this fix works.
