Application to get live USD/INR rate Using Python
In this article, we are going to write a python scripts to get live information of USD/INR rate and bind with it GUI application.
Modules Required:
- bs4: Beautiful Soup is a Python library for pulling data out of HTML and XML files.
Installation:
pip install bs4
- requests: This module allows you to send HTTP/1.1 requests very easily.
Installation:
pip install requests
Step-by-step Approach:
- Extract data from the given URL. Copy the URL, after selecting the desired location.
- Scrape the data with the help of requests and the Beautiful Soup module.
- Convert that data into HTML code.
- Find the required details and filter them.
Implementation:
Step 1: Import all the modules required.
Python3
# Import required modulesimport requestsfrom bs4 import BeautifulSoup |
Step 2: Create a URL get function
Python3
# Function to extract html datadef getdata(url): r=requests.get(url) return r.text |
Step 3: Now pass the URL into the getdata() function and convert that data(currency details) into HTML code.
The URL used here is https://finance.yahoo.com/quote/usdinr=X?ltr=1
Python3
# Extract and convertsoup = BeautifulSoup(htmldata, 'html.parser')result = (soup.find_all("div", class_="D(ib) Va(m) Maw(65%) Ov(h)") |
Output:
Step 4: Filter the currency details and quality(increment/decrement) according to the given data.
Python3
mydatastr = ''# Filter converted datafor table in soup.find_all("div", class_="D(ib) Va(m) Maw(65%) Ov(h)"): mydatastr += table.get_text()# Display outputprint(mydatastr) |
Output:
'73.2610-0.2790 (-0.38%)As of 3:30PM BST. Market open.'
Below is the complete program implemented using tkinter module.
Python
# Import required modulesfrom tkinter import *import requestsfrom bs4 import BeautifulSoup# user defined funtion# to extract currency detailsdef getdata(url): r = requests.get(url) return r.text # Function to compute and display currency detalisdef get_info(): try: soup = BeautifulSoup(htmldata, 'html.parser') mydatastr = '' for table in soup.find_all("div", class_="D(ib) Va(m) Maw(65%) Ov(h)"): mydatastr += table.get_text() list_data = mydatastr.split() temp = list_data[0].split("-") rate.set(temp[0]) inc.set(temp[1]) per_rate.set(list_data[1]) time.set(list_data[3]) result.set("success") except: result.set("Opps! someting wrong")# Driver Code # Create tkinter objectmaster = Tk()# Set background colormaster.configure(bg='light grey')# Variable Classes in tkinterresult = StringVar()rate = StringVar()per_rate = StringVar()time = StringVar()inc = StringVar()# Creating label for each informationLabel(master, text="Status :", bg="light grey").grid(row=2, sticky=W)Label(master, text="Current rate of INR :", bg="light grey").grid(row=3, sticky=W)Label(master, text="Increase/decrease by :", bg="light grey").grid(row=4, sticky=W)Label(master, text="Rate change :", bg="light grey").grid(row=5, sticky=W)Label(master, text="Rate of time :", bg="light grey").grid(row=6, sticky=W)# Creating lebel for class variableLabel(master, text="", textvariable=result, bg="light grey").grid(row=2, column=1, sticky=W)Label(master, text="", textvariable=rate, bg="light grey").grid(row=3, column=1, sticky=W)Label(master, text="", textvariable=inc, bg="light grey").grid( row=4, column=1, sticky=W)Label(master, text="", textvariable=per_rate, bg="light grey").grid(row=5, column=1, sticky=W)Label(master, text="", textvariable=time, bg="light grey").grid(row=6, column=1, sticky=W)# Create submit buttonb = Button(master, text="Show", command=get_info, bg="Blue").grid(row=0)mainloop() |
