Obtenga el precio de plata y oro en Tkinter usando Python

Requisito previo: BeautifulSoup , requests , tkinter , fecha y hora

En este artículo, vamos a discutir cómo obtener el precio del oro y la plata en la India usando Python en Tkinter. Hay una variación en el precio con el tiempo, el precio del oro y la plata se mueve por una combinación de oferta, demanda y comportamiento de los inversores.

Usaremos el sitio web de goodreturns para obtener el precio del oro y la plata. Crearemos múltiples funciones para diferentes operaciones:

• silver_price(): Esta función se utiliza para obtener el precio de la plata. Para plata, usaremos esta URL .
• gold_price(): Esta función se utiliza para obtener el precio del oro. Para Gold, usaremos esta URL .
• get_number_from_string(): esta función se usa para extraer números enteros o flotantes de una string.
• change_price(): Esta función se utiliza para obtener el precio del oro o la plata de un peso en particular. 

Enfoque paso a paso:

Paso 1#

Importar bibliotecas requeridas.

# Import Required library
from bs4 import BeautifulSoup
import requests
from tkinter import *
from datetime import date
from tkinter import ttk

Paso 2#

Obtenga precio de plata y oro.

# method to get the price of silver
def silver_price():
 
    # getting the request from url
    data = requests.get(
        "https://www.goodreturns.in/silver-rates/#Today+24+Carat+Gold+Rate+Per+Gram+in+India+%28INR%29")
 
    # converting the text
    soup = BeautifulSoup(data.text, 'html.parser')
 
    # finding metha info for the current price
    price = soup.find("div", class_="gold_silver_table right-align-content").find(
        "tr", class_="odd_row").findAll("td")
 
    # returning the price in text
    return price[1].text
 
 
# method to get the price of gold
def gold_price():
 
    # getting the request from url
    data = requests.get(
        "https://www.goodreturns.in/gold-rates/#Today+24+Carat+Gold+Rate+Per+Gram+in+India+%28INR%29")
 
    # converting the text
    soup = BeautifulSoup(data.text, 'html.parser')
 
    # finding metha info for the current price
    price = soup.find("div", class_="gold_silver_table right-align-content").find(
        "tr", class_="odd_row").findAll("td")
 
    # returning the price in text
    return price[1].text

Paso 3#

Obtenga un valor entero o flotante de la string.

# Extract Integer or Float from String
def get_number_from_string(string):
    return float(''.join([x for x in string if x.isdigit() or x == '.']))

Paso 4#

Obtenga el precio del oro y la plata por un peso particular.

# Get price for a particular weight
def change_price(weight_value):
 
    g_price = float(weight_value)*get_number_from_string(gold_price())
    s_price = float(weight_value)*get_number_from_string(silver_price())
 
    silver_price_label.config(text=f"{s_price} Rs")
    gold_price_label.config(text=f"{g_price} Rs")

A continuación se muestra la implementación basada en el enfoque anterior:

# Import Required library
from bs4 import BeautifulSoup
import requests
from tkinter import *
from datetime import date
from tkinter import ttk
 
 
# Extract Integer or Float from String
def get_number_from_string(string):
    return float(''.join([x for x in string if x.isdigit() or x == '.']))
 
 
# Returns the current local date
today = date.today()
 
 
# method to get the price of silver
def silver_price():
 
    # getting the request from url
    data = requests.get(
        "https://www.goodreturns.in/silver-rates/#Today+24+Carat+Gold+Rate+Per+Gram+in+India+%28INR%29")
 
    # converting the text
    soup = BeautifulSoup(data.text, 'html.parser')
 
    # finding metha info for the current price
    price = soup.find("div", class_="gold_silver_table right-align-content").find(
        "tr", class_="odd_row").findAll("td")
 
    # returning the price in text
    return price[1].text
 
 
# method to get the price of gold
def gold_price():
 
    # getting the request from url
    data = requests.get(
        "https://www.goodreturns.in/gold-rates/#Today+24+Carat+Gold+Rate+Per+Gram+in+India+%28INR%29")
 
    # converting the text
    soup = BeautifulSoup(data.text, 'html.parser')
 
    # finding metha info for the current price
    price = soup.find("div", class_="gold_silver_table right-align-content").find(
        "tr", class_="odd_row").findAll("td")
 
    # returning the price in text
    return price[1].text
 
 
# Get price for a particular weight
def change_price(weight_value):
 
    g_price = float(weight_value)*get_number_from_string(gold_price())
    s_price = float(weight_value)*get_number_from_string(silver_price())
 
    silver_price_label.config(text=f"{s_price} Rs")
    gold_price_label.config(text=f"{g_price} Rs")
