TypeError:‘encording’ is an invalid keyboard argument for this function

Question

原来程序是这样，我想打开num.txt这个文本，并且改名为file1.txt，但是一直报错
TypeError:‘encording’ is an invalid keyboard argument for this function

with  open(‘num.txt’,‘r’,encording=‘utf-8’) as file1:
contents = file1.read()
print(contents)

查找一些资料，改了后

import io
with  io.open(‘num.txt’,‘r’,encording=‘utf-8’) as file1:
contents = file1.read()
print(contents)

改完还是报错，求解

Answer 1

encoding,你打错字了
而且文件改名要用os.rename，你打开文件干什么
