Here is the code I have as project $4$:

import pandas as pd

class EMSystem:

def $\_\_$init$\_\_($self$)$:

self.employee$\_$list $=[]$

self.current$\_$log $=[]$

self.start$()$

self.printEmployeeList$()$

elif inp $==3$:

time $=$ input$("$Enter the current time $($HH:MM$)$: $")$

self.makeNewLog$($time$)$

elif inp $==4$:

break

else:

print$("$Invalid input. Please try again."$)$

def printWelcomeMessage$($self$)$:

print$("$Welcome to the Employee Monitoring System!"$)$

def printAllOptions$($self$)$:

print$("$What do you want to do today? $($input the number$)")$

print$("1-$ Set the employee list"$)$

print$("2-$ Show the employee list"$)$

print$("3-$ Make a new timestamp"$)$

print$("4-$ Close the EM System"$)$

def setEmployeeList$($self$)$:

file$\_$name $=$ input$("$Enter the file name $($employee$\_$list$1.$csv or employee$\_$list$2.$txt$)$: $")$

try:

if file$\_$name.endswith$(".$csv$")$:

self.employee$\_$list $=[$line$.$strip$().$split$(\text{'}\backslash$t$\text{'})$ for line in f$]$

else:

print$("$Invalid file format. Please use $.$csv or $.$txt$.")$

except FileNotFoundError:

except Exception as e:

print$($f$"$An error occurred: $\{$str$($e$)\}")$

def printEmployeeList$($self$)$:

if not self.employee$\_$list:

print$("$Employee list is empty."$)$

else:

print$("$Employee List:"$)$

for employee in self.employee$\_$list:

print$($f$"$ID: $\{$employee$[0]\},$ Name: $\{$employee$[1]\},$ Total Hours: $\{$employee$[2]\}")$

def makeNewLog$($self$,$ time$)$:

print$("$Employee list is empty. Please set the employee list first."$)$

return

self.current$\_$log $=[($employee$\_$id$,"$in$",$ time$)$ for employee$\_$id$,\_,\_$ in self.employee$\_$list$]$

while True:

employee$\_$id $=$ input$("$Enter employee ID to log in$/$out $($blank to finish$)$: $")$

if not employee$\_$id:

break

self.addEmployeeToLog$($employee$\_$id$,$ "out" if self.current$\_$log$[0][1]=="$in$"$ else $"$in$",$ time$)$

self.createTimestampLog$()$

def addEmployeeToLog$($self$,$ employee$\_$id$,$ status, time$)$:

for i$,($id$,\_,$ hours$)$ in enumerate$($self$.$employee$\_$list$)$:

self.employee$\_$list$[$i$][2]+=1$ if status $==$ "out" else $0$

break

def createTimestampLog$($self$)$:

print$("$

for employee$\_$id$,$ status, time in self.current$\_$log:

employee $=$ next$($e for e in self.employee$\_$list if e$[0]==$ employee$\_$id$)$

print$($f$"$ID: $\{$employee$[0]\},$ Name: $\{$employee$[1]\},$ Status: $\{$status$\},$ Time: $\{$time$\},$ Total Hours: $\{$employee$[2]\}")$

$")$

AksenchureCompany $=$ EMSystem$()$

Now here is the revised code:

import tkinter as tk

from tkinter import ttk

import pandas as pd

class EMSystem:

def $\_\_$init$\_\_($self$)$:

self.window $=$ tk$.$Tk$()$

self.window.title$("$Employee Monitoring System"$)$

self.employee$\_$list $=[]$

self.current$\_$log $=[]$

self.create$\_$gui$()$

self.window.mainloop$()$

def create$\_$gui$($self$)$:

label $=$ tk$.$Label$($self$.$window, text$=$"Employee ID:$")$

label.grid$($row$=0,$ column$=0)$

self.employee$\_$entry $=$ tk$.$Entry$($self$.$window$)$

self.employee$\_$entry.grid$($row$=0,$ column$=1)$

set$\_$employee$\_$button $=$ tk$.$Button$($self$.$window, text$=$"Set Employee List", command$=$self.set$\_$employee$\_$list$)$

set$\_$employee$\_$button.grid$($row$=1,$ columnspan$=2)$

def set$\_$employee$\_$list$($self$)$:

filename $=$ self.employee$\_$entry.get$()$

try:

self.employee$\_$list $=$ pd$.$read$\_$csv$($filename$).$values.tolist$()$

print$("$Employee list loaded successfully."$)$

except FileNotFoundError:

print$("$File not found. Please check the filename."$)$

except Exception as e:

print$("$An error occurred:", str$($e$))$

if $\_\_$name$\_\_=="\_\_$main$\_\_"$:

system $=$ EMSystem$()$

However, to satisfy the spec given in the image, the GUI created should display the $5$ options as buttons in a single window which the current revised code does not satisfy. Please revise it again to satisfy the spec.

Problem: EM System, Improved

Update the EMSystem from Project $4$ to have a GUI. The
