Whether you are applying for Python web development, crawler engineers, or data analysis, or automated operations, it involves some basic knowledge! I picked up some basic Python interview questions to see if you can answer them, maybe the students with the interview!Question 1: How can I modify the following Python code so that the following code calls the Show method of Class A?For:This topic examines the use of new and INIT, and using the new metho
