Python关于文件读写的疑惑。

t = input("文件:")
r = open(t,"r")
for line in r.readlines():
print(line)
r.close()

故障提示
Traceback (most recent call last):
File "C:/Users/HEZB/AppData/Local/Programs/Python/Python39/文件读写.py", line 3, in
for line in r.readlines():
UnicodeDecodeError: 'gbk' codec can't decode byte 0xad in position 8: illegal multibyte sequence

错误提示这个叫"Z“的文件找不到

把变量t打印出来看一下是什么，可能是程序执行的是没有输入一个正确的文件命名
可以把文件名直接卸载open函数中

f = open("filename",mode="r",encoding="utf-8") # 加上编码格式
for line in f: #直接in f 就好了
  print(line)
f.close()

r = open(t,"r", encoding="utf-8")

在open里加入一个参数:encoding="utf-8"

你们好，我加入编码格式后，故障代码是
raceback (most recent call last):
File "C:\Users\HEZB\AppData\Local\Programs\Python\Python39\文件读写.py", line 2, in
r = open(t,"r",encoding="utf-8")
FileNotFoundError: [Errno 2] No such file or directory: 'Z'
