KeyError: <tkinter.Entry object .!entry>
sorry for the dumb question ive been at this all day and cant seem to figure out what the problem is I sent the entire code above if someone can correct! I keep getting the same " KeyError: <tkinter.Entry object .!entry>" no clue what this means but I even watched a tutorial and my code was almost the same as the person in the tut yet there worked perfect please help!

Since Username is a reference to an Entry widget and data is a dictionary with string as the keys, so data[Username] will raise the exception.
Your checking should test whether e1.get() is a key in data and e2.get() should be equal to data[e1.get()].
Below is the suggested modification of cmd():
def cmd():
username = e1.get().strip()
password = e2.get().strip()
# both username and password have been input?
if username and password:
# load the credentials as a dictionary
with open("Data.txt") as db:
data = {}
for i in db:
a, b = i.split(", ")
data[a] = b.strip()
# check username and password
if username in data and data[username] == password:
messagebox.showinfo("Login Success", "Welcome")
# do whatever you want if login successful
else:
messagebox.showwarning("Login Failed", "Try again")
else:
messagebox.showwarning("Invalid", "Please enter both username and password")

https://realpython.com/python-keyerror/ :
A Python KeyError exception is what is raised when you try to access a key that isn’t in a dictionary ( in your case data ).
Here an example of content of the file 'Data.txt':
adam, a
bogdan, b
cicero, c
daniel, d
Below a making sense code of cmd() running without the error message:
def cmd():
db = open("Data.txt", "r")
d = []
f = []
for i in db.readlines():
print (i)
a, b = i.split(", ")
b = b.strip()
d.append(a)
f.append(b)
data = dict(zip(d, f))
print(data)
try:
if data[e1.get()] == e2.get():
messagebox.showinfo("Login success", "Welcome")
q=Tk()
q.mainloop()
else:
messagebox.showwarning("Wrong password entered", "Try again")
except KeyError:
messagebox.showwarning("Login failed dumb ass","Try again goofy")

How do I test functions using pytest

Hello,
I need your help writing test functions for the following functions using pytest: add_new_user, register_user, login_verify
I am trying to test my login system program using the pytest module which is a requirement for the end-semester project. The following are functions I am having trouble testing:
Function without parameters, but rather get information from the user.
Function that appends information to a text file.
Function that reads from a text file.

why am I getting cryptography fernet InvalidToken when using the same key

Hello so I am making a password manager and I want to encrypt the password file, so I generate and create the first password and when I read it and decrypt it reads it. And then when making another password it creates it but then when decrypting it throws an error. From what I can see I am using the same key.

The problem is that you take input of user for chosen account password then you append splitter and random generated password then '/n'. After that you encrypt this var using fernet. This method will work to view your first password since with first password you read and decrypt whole file but not with multiple encrypted passwords since each var encryption is unique (having different IV) which means that to decrypt all the passwords you will need a way to signal the end of an encrypted password and beginning of another encrypted password so that you pass to ferent the correct ciphertext with correct margins. This can be done by simply adding --END OF PASSWORD-- after each encryption write to password file. Then during reading of passwords you can just split pass file on these margins and pass result to fernet.
NOTE: dont use this code as your password manager since although you encrypt your passwords you are leaving your master password in mykey.key unencrypted which makes this totally useless.

Why does my function not execute when the condition is met?

I'm trying to make a login form for my server application and have stumbled onto an invisible error (the worst kind). I have a tries variable that increments by 1 every time the user enters the username incorrectly. When the tries variable reaches 3, the program should then execute the block() function. My issue is that it doesn't.
All my .txt files are blank so there's not an error there and everything seems fine. Please help because I'm pulling my hair out!
Here's the code:
import socket
import time
import sys
import os
tries = 0
def server():
def block():
#get host ip
ipBlock = socket.gethostbyname(socket.gethostname())
#create black list
ipBlackList = open("ipBlackList.txt", "w")
ipBlackList.close()
#read black list
ipBlackList = open("ipBlackList.txt", "r")
isBlocked = ipBlackList.readlines()
ipBlackList.close()
#disable account for 60 seconds
if ipBlock in isBlocked:
def countdown(t):
while t:
mins, secs = divmod(t, 60)
timer = '{:02d}:{:02d}'.format(mins, secs)
print('Your account has been temporarily disabled. Please
try again in '+timer, end=" seconds.\r")
time.sleep(1)
t -= 1
os.remove('ipBlackList.txt')
print('\nYour account has been re-enabled. You may log in
now.')
time.sleep(2)
t = 60
countdown(int(t))
block()
print("Enter administrator login details: ")
def usernameLogin():
#global vars
global tries
if tries == 3:
#read black list
ipBlackList = open("ipBlackList.txt", "r")
isBlocked = ipBlackList.readlines()
ipBlackList.close()
#get host ip
ipBlock = socket.gethostbyname(socket.gethostname())
if ipBlock not in isBlocked:
ipBlackList = open("ipBlackList.txt", "w")
ipBlackList.write(ipBlock)
ipBlackList.close()
block()
username = input("\nUsername: ")
#check if username exists
usernames = open("usernames.txt", "r")
checkUser = usernames.readlines()
usernames.close()
if username not in checkUser:
print("That username doesn't exist. Please try again.")
tries += 1
print(tries)
time.sleep(2)
usernameLogin()
print("im in")
time.sleep(3)
usernameLogin()
server()

In fact, your code do execute the block() function when tries==3, but in the begining of the block() you recreate the black list file, then you read the empty file and as a result the condition if ipBlock in isBlocked: is always false.
So, I've placed the commands that create the file out of the block(). Also, I've changed the remove of the black list file in the countdown() function and recreate but not delete it, because your code try to read it again when restarts to ask the username. Also I've set tries == 0 when block() ends. Also, the indentation at the end of countdown() was incorrect.
