Python 如何使用recipients属性对文件进行gpg加密？

我试图在python中使用recipients属性对文件进行GPG加密，但出现了一个错误

import os
import os.path
import time

gpg = gnupg.GPG(homedir='/home/ec2-user/.gnupg')

path = '/home/ec2-user/pgp'
ptfile = '/demo'

with open('/home/ec2-user/pgp/demo.txt', 'rb')as f:
        status = gpg.encrypt(f, recipients='email@domain.com', passphrase='secret')

print(status.ok)
print(status.stderr)

我得到以下错误：

[ec2-user@domain pgp]$ python3 pgp_encrypt.py
Traceback (most recent call last):
  File "pgp_encrypt.py", line 12, in <module>
    status = gpg.encrypt(f, recipients='email@domain.com', passphrase='secret')
  File "/home/ec2-user/.local/lib/python3.8/site-packages/gnupg/gnupg.py", line 1064, in encrypt
    result = self._encrypt(stream, recipients, **kwargs)
TypeError: _encrypt() got multiple values for argument 'recipients'

我犯了错误

[ec2-user@domain pgp]$ python3 pgp_encrypt.py
Traceback (most recent call last):
  File "pgp_encrypt.py", line 12, in <module>
     status = gpg.encrypt_file(f, recipients='email@domain.com', passphrase='secret')
AttributeError: 'GPG' object has no attribute 'encrypt_file'

如何修复代码

[ec2-user@domain pgp]$ python3 pgp_encrypt.py
Traceback (most recent call last):
  File "pgp_encrypt.py", line 12, in <module>
     status = gpg.encrypt_file(f, recipients='email@domain.com', passphrase='secret')
AttributeError: 'GPG' object has no attribute 'encrypt_file'

status = gpg.encrypt(f, symmetric=True, passphrase='Xcelenergy1!', encrypt=False)
