title: i am having a problem while calling the value of a key with tkinter .get() function
body: <blockquote>
    <p>Exception in Tkinter callback 100 Traceback (most recent call last):<br>
    File "D:\anaconda\lib\tkinter__init__.py", line 1702, in <strong>call</strong>
        return self.func(*args)   File "C:/Users/hp/PycharmProject/Financial Project/JournalEntries.py", line
    29, in Journal
        self.AccountCode = AccCode[Account_Title.get()] KeyError: '100'</p>
  </blockquote>
  
  <p>this is my dictionary:</p>
  
  <pre><code> AccCode = {100 : 'Cash',101 : 'Equipments', 102 : 'Supplies' , 103 : 'AccRec' , 104 : 'PreInsurance',
                     200 : 'AccPayable', 201 : 'NotesPay', 202 : 'InterestPayable', 203 : 'AccDepreciation' , 204 : 'Salaries and wages payable',
                     300 : 'Owner Capital', 301 : 'Owner Drawing',
                     400 : 'Service Revenue' , 401 : 'Rent Revenue',
                     500 : 'Salaries and wages Expense' , 501 : 'Utilities Expense' , 502 : 'Rent Expense' , 503 : "Insurance Expense" , 504 : 'Depreciation Expense' , 505 : 'Supplies expense' , 506 : ' Interest Expense' }
  </code></pre>
  
  <p>Although, when I am calling just <code>print(Account_Title.get())</code> it is giving me 100 as I am inputting 100 in tkinter entry.
  But when <code>self.AccountCode = AccCode[Account_Title.get()]</code>
  it gives key error. </p>
