我有一个Python脚本从互联网上下载任何文件。我遇到一个错误。

回溯（最近一次调用）：文件“C:/Users/PacY/PycharmProjects/filedownload/downloadfile.py”，第5行，打开（'C:/Users/PacY/Downloads'，'wb'）作为f:PermissionError:[Errno 13]权限被拒绝：'C:/Users/PacY/Downloads'

下面是代码。

link = input("Enter Url to be downloaded:")
file_url = requests.get(link)
with open('C:/Users/PacY/Downloads', 'wb') as f:
    f.write(file_url.content)```


I can't figure out why it's not working.

Thank you in advance for your help.
