Python KeyError(RSA Algorithm)

I am trying to execute this code but I am getting this error:
line 37, in \<module\>
encrypt(encryption_key_pair\[0\],encryption_key_pair\[1\],secret_message
line 22, in encrypt
enc_text = num_trans\[ord_num\]
KeyError: 32
\[Finished in 1.1s\]
Here's the part of the code:
from alphabet import transform, num_trans
from key_generator import generate_keys, encryption_key_pair, decryption_key_pair
#enc_key = [5,14]
#dec_key = [11,14]
secret_message = "abc"
encrypted_message = []
decrypted_message = []
def encrypt(e, modulus, message):
global enc_message
for character in message:
#print(character)
#enc_char = ord(character)
enc_char = transform[f'{character}']
#print(enc_char)
ord_num = (enc_char**e)%modulus
#print(ord_num)
#enc_text = chr(ord_num)
enc_text = num_trans[ord_num]
enc_message = encrypted_message.append(enc_text)
def decrypt(d, modulus, message):
global dec_message
for character in message:
decode_char = transform[f'{character}']
deord_char = (decode_char**d)%modulus
#print(deord_char)
dec_text = num_trans[deord_char]
dec_message = decrypted_message.append(dec_text)
encrypt(encryption_key_pair[0],encryption_key_pair[1],secret_message)
decrypt(decryption_key_pair[0],decryption_key_pair[1],encrypted_message)
print(encrypted_message)

DES Encryption in python error(TypeError: Object type <class 'str'> cannot be passed to C code)

I build des encryption_gui. I got error:

You need to pass bytes instead of str to DES.new() and pad(), so change the following lines:
text1 = t_p
...
key = t_key
to
text1 = t_p.encode()
...
key = t_key.encode()
Also the logic of pad() function is incorrect, it should be like below:
def pad(text):
n = len(text) % 8
if n:
n = 8 - n
return text + (b' ' * n)
Also you have defined pad() twice.
Note that AES should be used instead of DES.

Why won't Python script run after computer restart?

After a restart my script won't work anymore.
It worked before. Windows popping up, things needed to typed in and there was a result which I was happy with (like v0.9-alpha-happy). Now it yells at me.

All I did to solve this error was:

first_window.withdraw()
You forgot the () near Tk, so your not actually instantiating it properly.

exception used to pop up alert box from button event in tkinter, cant find out the root for the problem

so my program takes a directory with excel files with one line and combine them all into one.
The gui has two buttons one to choose the path and one to save the wanted path.
I created a gui class and im basically trying to pass the OptionMenu chosen text forward after an event was made, but an exception is raised and Im struggling with,
long story short:

For some reason it keeps returning from another path

solved it, had put all the methods inside the object, while the events func inside the init.
also i ran too many times the program so the errors were not related to my code...

Why is my Caesar Cipher program not displaying my encrypted message? Resolution is off too?

I am creating a Caesar Cipher program for class in Python and I was am getting errors when hitting the encrypt button. Also the sizes of the buttons are all out of whack and I can't figure out how to change that. I am very new to Python so please in simplest terms.
This is one of the errors I am getting

As you have it, it will return the value of the first line and ignore the second line.
Another possible error may be
for char in text:
I do not see where text has been initialized and passed into encrypt(message, key) You do not use the input argument message. It may be that you meant to use one where you used the other.
