通过Python新建一个文件gushi.txt，选择一首古诗写入文件中，再写一个另外的函数，读取指定文件gushi.txt，将内容复制到copy.txt中，并在控制台输出“复制完毕”，尽可能完善代码，添加异常处理。写的初级些

我可以回答这个问题。以下是Python代码：

# 写入古诗到gushi.txt文件中
def write_poem():
poem = "登高"
author = "杜甫"
content = "风急天高猿啸哀，\n渚清沙白鸟飞回。\n无边落木萧萧下，\n不尽长江滚滚来。"
with open("gushi.txt", "w", encoding="utf-8") as f:
f.write(f"{poem}\n{author}\n{content}")

# 读取gushi.txt文件并复制到copy.txt文件中
def copy_file():
try:
with open("gushi.txt", "r", encoding="utf-8") as f1, open("copy.txt", "w", encoding="utf-8") as f2:
f2.write(f1.read())
print("复制完毕")
except FileNotFoundError:
print("文件不存在")
except Exception as e:
print(f"发生错误：{e}")

# 调用函数
write_poem()
copy_file()
