AttributeError：'tuple'对象没有属性'encode'python gui

Question

我有这个错误AttributeError：'tuple'对象没有属性'encode'，这是我的代码的一部分。你能帮我吗

cur = conn.cursor()
sql = "SELECT * FROM farm_registration \
       WHERE barangay = %s", (e_barangay);
cur.execute(sql)
results = cur.rowcount

Answer 1

此语句返回元组

sql = "SELECT * FROM farm_registration \
       WHERE barangay = %s", (e_barangay);

你期待字符串，所以只需将上面的内容改为

sql = "SELECT * FROM farm_registration \
       WHERE barangay = %s" % e_barangay;
