About The Project
A Notepad in Python is designed using tkinter and the project file contains(notepad.py). Tkinter is a graphical user interface library from Python from which we will create more than one GUI app.
The use of a tkinter will broaden a notepad-like text editor. The notepad will have a menu where we are able to create a new file, open an existing file, save the file, edit, cut, copy, and paste.
This article is an open-source that allows the person to download and edit as consistent with their need.
Before you start to create a Python Notepad, make sure that you have Pycharm IDE installed on your computer.

Python Notepad Code Explanations
1. New File
Module for New File Functionality.
def new_file_logo(event=None):
global url
url = ''
text_editor.delete(1.0,tk.END)
file.add_command(label='new', image=new_logo ,compound=tk.LEFT, accelerator ='Ctrl+N',command=new_file_logo)The code above is for the new file feature. If you click on a new file, it will open a new document. If you want to open a new document faster, just press Ctrl+N on your keyboard.
2. Open File
Module for Open File Functionality.
def open_file_logo(event=None):
global url
url = filedialog.askopenfilename(initialdir=os.getcwd(), title='Select File', filetypes=(('Text File', '*.txt'), ('All files', '*.*')))
try:
with open(url, 'r') as fr:
text_editor.delete(1.0, tk.END)
text_editor.insert(1.0, fr.read())
except FileNotFoundError:
return
except :
return
main_screen_window.title(os.path.basename(url))
file.add_command(label='Open', image=open_logo ,compound=tk.LEFT, accelerator ='Ctrl+O',command =open_file_logo)In the code above, which is for the open file feature to open a document file on your computer. Pressing Ctrl+O on the keyboard lets you open more than one file at once.
3. Save
Module for Save Functionality.
ef save_file_logo(event=None):
global url
try:
if url:
content = str(text_editor.get(1.0,tk.END))
with open(url, 'w', encoding='utf-8') as fw:
fw.write(content)
else :
url = filedialog.asksaveasfile(mode='w', defaultextension='.txt', filetypes=(('Text File', '*.txt'),('All files','*.*')))
content = text_editor.get(1.0, tk.END)
url.write(content)
url.close()
except :
return
file.add_command(label='Save', image=save_logo, compound=tk.LEFT, accelerator ='Ctrl+S', command=save_file_logo)In the code shown above, which is for the Save your document. Click FILE > Save, choose or browse to a folder, give your document a name in the File name box, and click Save or save your work as you go by pressing Ctrl+S.
4. Exit
Module for Exit Functionality.
def exit_module(event=None):
global url, text_changed
try:
if text_changed:
boxmessage = messagebox.askyesnocancel('Warning','Do you want to save the file')
if boxmessage is True :
if url:
content = text_editor.get(1.0,tk.END)
with open(url,'w',encoding='utf-8') as fw:
fw.write(content)
main_screen_window.destroy()
else:
content2 = str(text_editor.get(1.0,tk.END))
url = filedialog.asksaveasfile(mode='w',defaultextension='.txt',filetypes=(('Text File','*.txt'),('All files','*.*')))
url.write(content2)
url.close()
main_screen_window.destroy()
elif boxmessage is False:
main_screen_window.destroy()
else:
main_screen_window.destroy()
except:
return
file.add_command(label='Exit', image=exit_logo, compound=tk.LEFT, accelerator='Ctrl+Q', command=exit_module)In the code above, “Exit” is a command line on the File menu that lets you close the Notepad application when you’re done working on your document.
5. Search
Module for Search or Find Functionality.
def search_module(event=None):
def find():
word = entry_find.get()
text_editor.tag_remove('match','1.0',tk.END)
matches = 0
if word:
start_pos = '1.0'
while True:
start_pos = text_editor.search(word, start_pos, stopindex=tk.END)
if(not start_pos):
break
end_pos = f'{start_pos}+{len(word)}c'
text_editor.tag_add('match',start_pos,end_pos)
matches +=1
start_pos=end_pos
text_editor.tag_config('match',foreground='red',background='')
In the code shown above, which is for finding a word that will turn red if it is correct?
