I want to code a short programme. My idea was to code a login window. Then the next window opens and then I should be able to encrypt a text I wrote into a ScrolledText. The whole encryption should be done with the ceasar principal. I combined my code(at the bottom) with this one:
def caesar(text, schluessel):
geheim = ''
for i in text:
number = ord(i) + schluessel #122 = 119+3
if number > 122:
number -= 26
elif number == 32 + schluessel: #whitespace
number = 32
letter = chr(number)
geheim += letter
print(geheim)
I recieved this error message:
Exception in Tkinter callback
