Really small en/decode program written in python

[newchild]

Yes I know this is not a masterpiece of codes(It is full of bugs, has ugly namings and an unproper use of Object-oriented programming) but it still can be useful as a bad example.

class encode(object):
    def __init__(self,list=[],real_list=[]):
        self.list=list
        self.real_list=real_list



    def stringtofloat(self,string):
        if string.lower()=='a':
            self.l=1*self.key
        if string.lower()=='b':
            self.l=2*self.key
        if string.lower()=='c':
            self.l=3*self.key
        if string.lower()=='d':
            self.l=4*self.key
        if string.lower()=='e':
            self.l=5*self.key
        if string.lower()=='f':
            self.l=6*self.key
        if string.lower()=='g':
            self.l=7*self.key
        if string.lower()=='h':
            self.l=8*self.key
        if string.lower()=='i':
            self.l=9*self.key
        if string.lower()=='j':
            self.l=10*self.key

So you might want to have a look at this

Here you should write text = str(input('text')) instead of text=input('text'), then it's not needed to write the input text int "" xD
