    <p>I trying my hands on python. I am trying to implement a crypto class which does enc/dec . In my crypto class i require user to pass 3 args to do the enc dec operations. Till now i was reading key from file and doing the operations. Now i want to provide a generate key function also. But problem is that to call generate keys i dont want user to provide any arguments while initiating the class. </p> <p>So what essentially i am trying to achieve is that when the crypto class is instantiated without giving any arguments, i just want to expose generate_key function. and when all the 3 args are provided while instantiating class, I want to expose all other enc/dec functions but not key gen function. </p> <p>I am not able to understand is it a polymorphism situation, or inheritance or should i just use 2 different classes one having generate keys and other for enc dec functions..</p> <p>Please give me some suggestion about how can i handle this situation efficiently?</p> <p>Example: </p> <pre><code>class crypto: def __init__(self,id, val1): self._id = id self._val1 = val1 def encrypt(self): """ encryption here """ def save(self): """ save to file """ def load(self): """ load from file""" def decrypt(self): """ decryption here""" def gen_keys(self): """ gen key here""" </code></pre> <p>So Now, when this crypto class is instantiate with no arguments, i just want to expose gen keys function. and if it is instantiated with the id and val1, then i want to expose all functions but not gen keys.</p> <p>I hope this will provide some clarification about my question. Please suggest me how can i achieve this.</p> <p>Thanks, Jon </p>

    1. COI'm not following your question. Can you provide a (pseudo)code example of the interfaces you are explaining?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
