[已解决]字符型 转化 整型

喵叔

['0x20', '0x30', '0x09', '0x54', '0x00', '0x2a', '0x05', '0x00', '0x00', '0x00', '0x00', '0x00', '0x7e', '0x86', '0x4e', '0x0d', '0x00', '0x00', '0x02', '0x00', '0x18', '0x03', '0x14', '0x03', '0x09', '0x43', '0x58', '0xff']
<class 'str'>
数据类型如上
想将所有的列表都转化为int 型
报错
invalid literal for int() with base 10: '0x20'

但是我直接输入0x20 默认就是int形

求大佬解

int('0x20',16)
