python postgresql TypeError: not all arguments converted during string formatting

Question

命令“INSERT into route_list VALUES ('0.0.0.0/0')”没有问题。但是循环不起作用。这个错误是什么意思？以及如何摆脱她？

data = ['0.0.0.0/0']

for d in data:

  cursor.execute("INSERT into route_list VALUES %s", d)

TypeError：在字符串格式化期间并非所有参数都已转换

Answer 1

使用这个：

cursor.execute("INSERT into route_list VALUES (%s)", [d])
or
cursor.execute("INSERT into route_list VALUES (%s)", (d,))
or
cursor.execute("INSERT into route_list VALUES ('{0}')".format(d))
