我的 sqlite3 数据库出了什么问题？

Question

I try to open a connection to my sqlite database, when this happens:

Traceback (most recent call last):
  File "/Users/amirjodelmans/Desktop/chemcalc.py", line 3, in <module>
    hassan = sqlite3.connect("Untitled/Applications/molairemassa.db")
sqlite3.OperationalError: unable to open database file

The database can be found in the exact map, as shown in the error message, and this is the only code I've written:

import sqlite3

hassan = sqlite3.connect("Untitled/Users/amirjodelmans/Applications/molairemassa.db")

Does anybody know how to fix this?

Answer 1

It seems that you just put the wrong path in the string.

Could you try to change your path to an absolute path like this:

import sqlite3

hassan = sqlite3.connect("/Users/amirjodelmans/Applications/molairemassa.db")

Generally, if a path starts with / , it means an absolute path, if path starts with ./ or other alphanumerics, it represents an relative path.
