according to the link i posted: "if we use the .fetchall() method, we return a list of tuples from the database query, where each tuple represents one row entry. " so it shouldn't be an issue that it displays [(0,)] instead of 0

c = conn.cursor() name = 'John' check = c.execute('SELECT count(name) FROM table_name') c.fetchall() >>> ([0,]) I need at least 0 instead of ([0,])
