Question

以下代码在尝试在'<'和datetime.timedelta之间使用datetime.datetime时失败

cert_install_status.get('CertificateExpirationDate') -> 2020-12-31 00:00:00type(cert_install_status.get('CertificateExpirationDate')) -> <class 'datetime.datetime'>

失败代码，

if (cert_install_status.get('CertificateExpirationDate') - datetime.now()) < (datetime.today() + timedelta(365)):
TypeError: '<' not supported between instances of 'datetime.timedelta' and 'datetime.datetime'
