Here is an article that provides a step -by -step guide on how to achieve its goal using Python and the Tkinter library.
Ethereum API call: live calculations with Tkinter
In this article, we will guide it through the configuration of a simple TKINTER application that makes calls API for Binance Exchange and show live calculations in real time.
Prerequisites
- Install python 3.7 or higher
- Install the ‘Applications’ library using PIP:
PIP Install applications'
- Install thetkinter
library using pip:pip install tk
Step by step instructions
1. Define its URL and API function
Create a new file calledAPI.py. This file will keep its API UR and work to make the call.
Python
Import requests
Binance Exchange API URL
API_URL = "
Def get_binance_price (Ticker):
Make an API call
Answer = Requets.get (API_URL, Params = {"Symbol": Ticker})
if answer.status_code == 200:
Return response.json () ["Price"]
others:
print (f "Error: {Response.status_code}")
It does not return any
Example use
Ticker = "Btcusdt"
Price = Get_binance_Price (Ticker)
If the price is none:
PRINTING (F "The current price of Bitcoin is: $ {Price: .2f}")
2. Create the Tkinter
window
Open a new file calledMain.pyand add the following code to create the Tkinter window:
Python
import tkinter as tk
Initialize tkinter
root = tk.tk ()
Root.title ("Ethereum Api Call")
Create label to show live calculations
Label = tk.label (root, text = "current price:")
Label.pack ()
Create button to run the so -called API
DEF BUTTON_CLICK () ::
Ticker = Input ("Enter the Bitcoin symbol:")
Price = Get_binance_Price (Ticker)
If the price is none:
label
Delete the label after 3 seconds
Def Clear_Label () ::
Root.fter (3000, Clear_Label)
Clear_Label ()
Create button to run the so -called API
button = tk.button (root, text = "run", commander = button_click)
button.pack ()
Start tkinter event loop
Root.Mainloop ()
Explanation
In this article:
- First we import the required libraries: 'Requests to make calls API and’ tkinter
to create the Gui.
- TheAPI.py
defines a function for calling API for Binance Exchange and returns the current price of a specified bitcoin symbol.
- In theMain.py
file, we create a TKINTER window with a label that shows live calculations and a button to run a call API. When clicking on the button, request your entrance (Bitcoin symbol) and shows the current price in real time using theGet_binance_price ()function.
- We use theafter () method to program the execution of the` Clear_Label () function after 3 seconds. This deletes the label and updates the calculation screen.
Example use cases
You can execute this code on your local machine to see it in action. Simply enter a bitcoin symbol when asked and see the current live price update in the window.
Note: Be sure to have an active Internet connection for API calls to work properly.
This is a basic example of how to achieve live calculations with Tkinter using API. You can improve this code by adding more functionality or error management as necessary.
