Selenium + Python + UnexpectedAlertPresentException: Dealing with annoying alerts

By Viksto
Handling  UnexpectedAlertPresentException   Alerts who hates them? I Do!  Who doesn't hate an annoying alert causing your tests / scraping job to fail? I must say they are pretty much on point on the Unexpected part!  Fortunately, there are easy ways to mitigate the issue. 1. Disable alerts completely: driver . execute_script( 'window.alert = function(){};' ); execute this script just before where you anticipate the alert and you're golden. 2. You want to see the alert text but not disturb the execution flow. driver . execute_script( 'window.alert = console.info;' ); Now the alerts have been redirected to the console and you don't have to worry about them. (Unless you have to - then you'd have to monitor the console) 3. You know exactly when it comes and want to accept the alert and move on. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 from selenium import webdriver from selenium.webdriver.s...

Python Program for Soundex Algorithm

By Viksto
This is a python implementation for Soundex Algorithm. This Program builds a JSON document as a dictionary and is kept on building at every execution. Its constantly appended and referenced while the program  is executed. Program: from re import sub def remove_symbols (input_string): #Convert the characters to lower case and then use #Regular expressions to remove non a-z chars return sub( '[^A-Z]+' , '' , input_string) def clean (input_string): #Convert the characters to lower case and then use #Regular expressions to remove non a-z chars return sub( '[^a-z]+' , '' , input_string . lower()) word = "Input" def soundex (word): #Step 1: Capitalize all letters in the word and drop all punctuation marks. word = remove_symbols(word . upper()) #Step 2: Retain the first letter of the word. first_letter = word[ 0 ] word = word[ 1 :] #Step 3 & 4: Change ( 'A...
