I'm using Tkinter and I was abble to find only a file browser:
filename = tkFileDialog.askopenfilename(parent = root, title = 'Open file to encrypt')
or only a directory browser:
dir = tkFileDialog.askdirectory(parent = root, title = 'Open file to encrypt')
Summary: in this tutorial, you’ll learn how to show an open file dialog in Tkinter applications.,When developing a Tkinter application that deals with the file system, you need to provide a dialog that allows file selections.,To do that, you can use the tkinter.filedialog module. The following steps show how to display an open file dialog:,Use the askopenfilename() function to display an open file dialog that allows users to select one file.
First, import the tkinter.filedialog
module:
.wp - block - code {
border: 0;
padding: 0;
}
.wp - block - code > div {
overflow: auto;
}
.shcb - language {
border: 0;
clip: rect(1 px, 1 px, 1 px, 1 px); -
webkit - clip - path: inset(50 % );
clip - path: inset(50 % );
height: 1 px;
margin: -1 px;
overflow: hidden;
padding: 0;
position: absolute;
width: 1 px;
word - wrap: normal;
word - break: normal;
}
.hljs {
box - sizing: border - box;
}
.hljs.shcb - code - table {
display: table;
width: 100 % ;
}
.hljs.shcb - code - table > .shcb - loc {
color: inherit;
display: table - row;
width: 100 % ;
}
.hljs.shcb - code - table.shcb - loc > span {
display: table - cell;
}
.wp - block - code code.hljs: not(.shcb - wrap - lines) {
white - space: pre;
}
.wp - block - code code.hljs.shcb - wrap - lines {
white - space: pre - wrap;
}
.hljs.shcb - line - numbers {
border - spacing: 0;
counter - reset: line;
}
.hljs.shcb - line - numbers > .shcb - loc {
counter - increment: line;
}
.hljs.shcb - line - numbers.shcb - loc > span {
padding - left: 0.75 em;
}
.hljs.shcb - line - numbers.shcb - loc::before {
border - right: 1 px solid #ddd;
content: counter(line);
display: table - cell;
padding: 0 0.75 em;
text - align: right; -
webkit - user - select: none; -
moz - user - select: none; -
ms - user - select: none;
user - select: none;
white - space: nowrap;
width: 1 % ;
}

import filedialog as fdCode language: Python(python)
Second, call the fd.askopenfilename()
function to show a dialog that allows a single file selection:
filename = fd.askopenfilename() Code language: Python(python)
The program:
import tkinter as tk from tkinter import ttk from tkinter import filedialog as fd from tkinter.messagebox import showinfo # create the root window root = tk.Tk() root.title('Tkinter Open File Dialog') root.resizable(False, False) root.geometry('300x150') def select_file(): filetypes = ( ('text files', '*.txt'), ('All files', '*.*') ) filename = fd.askopenfilename( title = 'Open a file', initialdir = '/', filetypes = filetypes) showinfo( title = 'Selected File', message = filename ) # open button open_button = ttk.Button( root, text = 'Open a File', command = select_file ) open_button.pack(expand = True) # run the application root.mainloop() Code language: Python(python)
The askopenfile()
function displays a file dialog and returns a file object of the selected file:
f = fd.askopenfile() Code language: Python(python)
And the askopenfiles()
function shows a file dialog and returns file objects of the selected files:
f = fd.askopenfiles() Code language: Python(python)
In most cases, we use the filedialog.askopenfilename() function to ask the user to browse and open a file from the system. Based on the selection of the filetype, the script is programmed to perform write or read operation.,How to copy certain files from one folder to another using Python?,How to read all files in a folder to a single file using Java?,If you have ever wondered how the dialogboxes work in a Python application, then you probably end up hearing the filedialog module in Tkinter. The filedialog module contains a number of built-in functions which can be used to display various types of dialogs for dealing with files in the system.
Example
# Import the library from tkinter import * from tkinter import filedialog # Create an instance of window win = Tk() # Set the geometry of the window win.geometry("700x300") # Create a label Label(win, text = "Click the button to open a dialog", font = 'Arial 16 bold').pack(pady = 15) # Function to open a file in the system def open_file(): filepath = filedialog.askopenfilename(title = "Open a Text File", filetypes = (("text files", "*.txt"), ("all files", "*.*"))) file = open(filepath, 'r') print(file.read()) file.close() # Create a button to trigger the dialog button = Button(win, text = "Open", command = open_file) button.pack() win.mainloop()
Select and open a text file and the console will display all the content of the file.
Centralized Database Vs Blockchain
A blockchain can be both permissionless(like Bitcoin or Ethereum) or permissioned(like the different Hyperledger blockchain frameworks).A permissionless blockchain is also known as a public blockchain, because anyone can join the network.A permissioned blockchain, or private blockchain, requires pre - verification of the participating parties within the network, and these parties are usually known to each other.
Types of Blockchains
The choice between permissionless versus permissioned blockchains should be driven by the particular application at hand(or use
case).Most enterprise use cases involve extensive vetting before parties agree to do business with each other.An example where a number of businesses exchange information is supply chain management.The supply chain management is an ideal use
case
for permissioned blockchains.
You would only want trusted parties participating in the network.Each participant that is involved in the supply chain would require permissions to execute transactions on the blockchain.These transactions would allow other companies to understand where in the supply chain a particular item is.
