Program gives error but doesn't say where the error is. - FWendeburg - Mar-08-2019
Hi, i'm making an encryption algorithm but when I test it it gives me a strange error which i can't correct because it doesn't say where. I only have the encryption function for now.
The code:
"""A funciton to encrypt a given text."""
from random import randint
class w_encryption():
"""A class with a method to encrypt text and a method to decrypt text."""
def __init__(self, text):
"""Declares the variables used within the methods."""
self.text = text
self.encrypted = []
self.return_encrypted = ''
def _encrypt_(self):
"""Encrypts a text."""
for character in self.text:
# Encrypts lowercase letters.

You are going to have to be more specific about how you are testing it. It works fine when I run it. That doesn't look like an error, it looks like the repr for an instance of w_encryption. My guess is your test is returning the encryption object when it should be returning the encrypted text.
Edit: for example:
Output:>>> test = w_encryption('Avalokiteshvara')
>>> test._encrypt_()
'14061962245146643241220108292105138248193963515807825'

You can save yourself a whole lot of lines of code by using a dictionary
encr_dict={'a':(1, 50)
'b':(300, 400)}
if echar in encr_dict:
echar = randint(encr_dict(echar))
self.encrypted.append(echar)
## etc
## replaces
if character == 'a':
echar = randint(1, 50)
self.encrypted.append(echar)
elif character == 'b':
echar = randint(300, 400)
self.encrypted.append(echar) Finally, how are you going to decode it since you don't know which random number was used to encode it?

Thanks for your response!
I was doing:
test = w_encryption('hello')
test._encrypt_()
print(test)Haha that's why I got "<__main__.w_encryption instance at 0x0000000003988548>" in response. (Mar-09-2019, 01:22 AM)woooee Wrote: You can save yourself a whole lot of lines of code by using a dictionaryencr_dict={'a':(1, 50)

But I already wrote the code for 80+ characters. Haha
