I assume you have checked that the folder exists? and
that you (ie. the user running the program) have permission
to go there?
def add_func(dt, ds, at):
'''Insert data into db(L2)'''
sql_insert = """
INSERT INTO expenses (date, desc, amount)

""" % (dt, ds, at)
os.chdir(sqlite3_path)
# open connection to database
try:
cx = sqlite.connect(database)
except sqlite.Error(errmsg):
print ("Can not open ") +str(errmsg)
# insert data into table
try:
cu = cx.cursor()
cu.execute(sql_insert)
cx.commit()
except sqlite.Error(errmsg):
print ("Can not execute: ") +str(errmsg)
# close connection
cx.close()
BTW Its probably better to set the database to the full path rather than
change into the folder for every access of the database.
In fact I usually just open the database once at the start
of my program. The data functions then only need to create
a cursor (in fact I often keep the cursor open too!).
That reduces the work in each function and the duplication of code
although you could put the open and cursor code into a function
called by the other data functions - that would help with
maintenance in future.
