Calling a function means that you execute the function that you have defined - either directly from the Python prompt or through another function (as you will see in the section “Nested Functions”). Call your newly defined function hello() by simply executing hello(), just like in the ...

有关密钥派生函数的更多信息,请访问cryptography.io/en/latest/hazmat/primitives/key-derivation-functions/。 在这个例子中,我们使用这个函数从密码生成一个密钥,并使用该密钥创建我们用于加密和解密数据的 Fernet 对象。在这种情况下,要加密的数据是一个简单的消息字符串。我们可以使用verify()方法,检查从提供的密钥派...
All python initialization module functions need to be named init<module_name> - this is how python knows which function to call in your extension module. All it needs to do right now is to register the module with the list of static methods you supplied. Wi...
