Table not found PythonAnywhere

Question

I am trying to access a table within a .db file using sqlite3 in Python Anywhere. The code works properly when I run it locally, but it doesn't work when I host it on the website. Here is the code.

con = sqlite3.connect("/home/routsiddharth/mysite/finance.db", check_same_thread=False)
con.row_factory = sqlite3.Row

cur = con.cursor()

cur.execute(f"SELECT * FROM users WHERE username = '{username}'")

The error I am getting is below.

    rows = reformat(cur.execute(f"SELECT * FROM users WHERE username = '{username}'"), "users")
#033[33msqlite3.OperationalError: no such table: users#033[0m

Where is the problem?
