Here is an article that offers step-by-step instructions to achieve your target with Python and the Tkinter library.
Ethereum api call: Live calculations with tkinter
In this article we will guide you by setting up a simple tkinter application with which API calls at Binance Exchange and live calculations are displayed in real time.
requirements
- Install Python 3.7 or higher
- Install the “Requests” library with PIP:
PIP installation requirements"
- Install thetkinter
library with PIP:PIP Install TK
Step-by-step instructions
1. Define your API URL and function
Create a new file calledapi.py. This file keeps your API URL and function to make the call.
Python
Import inquiries
Binance Exchange API URL
Api_url = "
DEF get_binance_price (ticker):
API call
Answer = Requests.Get (api_url, params = {"symbol": ticker})
if response.status_code == 200:
return response.json () ["price"]
different:
print (f "error: {response.status_code}"))
none back
Example use
Ticker = "btcusdt"
price = get_binance_price (ticker)
If the price is not:
Print (f "The current price for Bitcoin is: $ {price: .2f}")
2. Create the Tkinter window
Open a new file called main.py and add the following code to create the Tkinter window:
`Python
Import the tkinter as a TK
Initialize Tkinter
root = tk.tk ()
root.title ("Ethereum api call")
Create label to display live calculations
Label = tk.label (root, text = "Current price:")
Label.pack ()
Create button to carry out the API call
Def button_click ():
Ticker = input ("Enter Bitcoin symbol:")
price = get_binance_price (ticker)
If the price is not:
Label.config (text = f "The current price of {ticker} is: $ {price: .2f}")
Delete the label after 3 seconds
Def Clear_Label ():
root.after (3000, clear_label)
Clear_label ()
Create button to carry out the API call
Button = tk. button (root, text = "execute", command = button_click)
button.pack ()
Start the Tkinter -Evisisschleife
root.mainloop ()
Explanation
In this article:
- We first import the necessary libraries: “Inquiries” to make API calls and ‘tkinter’ to create the GUI.
- The file “API.PY” defines a function with which API calls can be made to exchange Binance and returns the current price of a specific Bitcoin symbol.
- In the “Main.py” file we create a tkinter window with a label with the live calculations and a button to carry out an API call. If you click on the button, you will be asked for your input (Bitcoin icon) and the current price is shown in real time in real time in real time.
- We use the “After ()
method to plan the execution of the functionClear_Label ()` after 3 seconds. This deletes the label and updates the calculation display.
Example application cases
You can run this code on your local computer to see it in action. Simply enter a Bitcoin symbol when you are asked and you will see the current price update live in the window.
Note: Make sure that you have an active internet connection so that API calls work properly.
This is a basic example of how live calculations can be achieved with APIs with a tkinter. You can improve this code by adding more functions or error treatments as required.
