1. 用默认方式打开：

(.venv) (base) metal@metal-Lenovo-Product:~/project/PAutomationCookbook/ch04$ echo $LANG
zh_CN.UTF-8
(.venv) (base) metal@metal-Lenovo-Product:~/project/PAutomationCookbook/ch04$ cat example_iso.txt
20�(.venv) (base) metal@metal-Lenovo-Product:~/project/PAutomationCookbook/ch04$ cat example_utf8.txt
20£
(.venv) (base) metal@metal-Lenovo-Product:~/project/PAutomationCookbook/ch04$ python

#utf-8编码的文件可以打开

>>> with open('example_iso.txt') as file:
... print(file.read())
...
Traceback (most recent call last):
