1) What Is Python? What Are The Benefits Of Using Python?
Python is a programming language with objects, modules, threads, exceptions and automatic memory management. The benefits of pythons are that it is simple and easy, portable, extensible, build-in data structure and it is an open source.
2) How Python Can Be Used In Software Testing?
- To generate test data; parse test results; generate reports; testing API calls etc.

Explicit wait makes the browser wait for a given duration or the condition is true else, it will throw a time exceeded exception
Implicit wait- will make the browser wait for a defined time and the execution continues
25) What are window handles?
During the script execution if there is a new window that pops up then they have an address and they have a handle, each handle is listed in the variable handles
Ex: To reference those windows driver.switch_window(browser.wondow(handle))
26) What are alerts and how do you handle?
Alerts are the popup windows that you get when there is notification to the user,
Handling them: alert_var = browser.switch_to_alert()
To dismiss: alert_var.dismiss()
To accept: alert_var.accept() etc

integer,string,float and complex are the supported data types in python
83) What is MRO in python
Method Resolution order is used in inheritance concepts
where class is inheriting multiple class and in all the parent class, same method is defined. Child class is confused which method to call during run time. So the MRO helps to resolve the issue.
84) How will identify when web element doesn’t have any of the unique locater.
