python文件打开报错TypeError: an integer is required (got type str)求解

打开代码如下：

f=open("123.txt","rt","encode=utf-8")
 for i in f:
    i=i.split(",")
    print(i)

报错如下：

=RESTART: C:\Users\Zz\AppData\Local\Programs\Python\Python38-32\program\practise11.py
Traceback (most recent call last):
    File "C:\Users\Zz\AppData\Local\Programs\Python\Python38-32\program\practise11.py", line 1, in <module>
    f=open("123.txt","rt","encode=utf-8")
TypeError: an integer is required (got type str)

``

这是我想打开输出的文件

另外，为什么我的文件里有逗号的话，open就需要写“encode=utf-8”?

求大神解答

f=open("123.txt","rb+",encoding="utf-8")

你的文档有中文就要encoding

没有用

报错信息里指示 f=open("123.txt","rt","encode=utf-8") 里有 type error, 是参数类型错误，编码参数要加参数名称，另外这条语句还有其它错误：
正确写法： f=open("123.txt","rb",encoding="utf-8")
