Question

I’m trying to have python recall the ‘enstring’ variable I set using the ‘crypto’ method I created so I can use it in the ‘decrypto’ method.

class encryptString():
    def crypto(self, string):
        enstring = base64.b64encode(string)
        print enstring
    def decrypto(self, enstring):
        destring = base64.b64decode(enstring)
        print destring

So, I want ‘crypto’ to set ‘enstring’ as the variable for the encoded string. However, when I call the variable after using the ‘crypto’ method, I get the “enstring is not defined” error.
How can I fix this?

Answer 1

Use self.enstring both times. Do the same for destring. Don’t pass enstring to decrypto as it’ll be part of self.

class encryptString():
    def crypto(self, string):
        self.enstring = base64.b64encode(string)
        print self.enstring
    def decrypto(self):
        self.destring = base64.b64decode(self.enstring)
        print self.destring

This way, enstring and destring are instance attributes, so they’re not lost when the crypto and decrypto methods return.
