Python interview questions covering recursion, data types, exception handling, memory management, and more.

• Recursion is a function that calls itself. Example: factorial function.

• Python data types include integers, floats, strings, lists, tuples, and dictionaries.

• Negative indexing allows you to access elements from the end of a list or string. Example: my_list[-1] returns the last element.

• Exceptions are handled using try-except blocks. Example: try: some_code except SomeExcept...read more

A generator is a function that returns an iterator object. It generates a sequence of values on the fly.

• Generators are used to create iterators for lazy evaluation of a sequence of values.

• They are memory efficient as they generate values on the fly instead of storing them in memory.

• Generators are used in Python for creating infinite sequences, reading large files, and processing data in chunks.

• Example: def my_generator(): yield 1; yield 2; yield 3; for i in my_generator(): pr...read more

Print odd index elements from list1 and even index elements from list2 and combine them into a third list.

• Loop through both lists and use conditional statements to append the elements to the third list.

• Use the modulo operator to check for odd/even index.

• Final list should contain [6, 4, 12, 12, 18, 20].

Software Test Life Cycle (STLC) is a sequence of activities carried out to ensure quality in software testing. Bug Life Cycle is a process followed by the testing team to track and manage bugs found during testing.

• STLC includes planning, designing, executing, and reporting of tests.

• Bug Life Cycle includes bug identification, reporting, assigning, fixing, retesting, and closing.

• STLC ensures that the software meets the requirements and is of high quality.

• Bug Life Cycle ensures ...read more

Answers to technical questions for Senior Automation Test Engineer position.

• chmod 644 example.txt permission means the owner has read and write access, while others have only read access.

• XPath is a language used to locate elements in an XML document or HTML page.

• To find an element by XPath in Selenium, use the findElement() method with the By.xpath() locator. For example: driver.findElement(By.xpath("//input[@id='username']"));
