You can prepare for a programming interview by using Python questions and answers that have been provided for job interviews. Python will be the focus of the questions that are asked in the interview. These quizzes will assist you in recalling important information regarding Python programming.
These are not full lessons; rather, they are a series of test questions designed to help you identify areas in which your Python knowledge is lacking. You will be able to strengthen the parts of your programming in Python that need it the most.
The questions and answers pertaining to Python are organised into three distinct categories: basic, advanced, and exam-style questions. Each category is dedicated to discussing a particular subject. As an illustration, the questions in the Python Scripting section concentrate on the letters “a,” “w,” and “r.”
How is Python an interpreted language?
Python is an interpreted language. It means that your Python code has to be translated into machine-readable binary before it can run. This happens when you run the Python program, and this process is called interpretation.
Python is a high-level programming language. A high-level programming language uses short keywords instead of complicated commands to instruct the computer, which makes it easy for humans to read and write programs in them. For example, instead of writing out binary codes for each command or statement like “START” (which tells your computer to start running), “ADD” (which adds numbers together), etc., you just need to use shorter keywords like print() or if else statements
What is the difference between list and tuple?
List and tuple are the two types of collections in Python. The difference between them can be explained using their parameters:
- List is a mutable sequence, while tuple is an immutable sequence. You can add or remove items from the list but this operation won’t affect the original data structure itself. On the other hand, you cannot modify any item within a tuple.
- List can be indexed and sliced whereas tuple cannot be indexed or sliced.
- Lists can be reversed whereas tuples cannot be reversed since they are immutable sequences that do not contain any positional indexing information like lists do (they only have an integer index).
What is namespace in Python?
In Python, the namespace is a way to organize all the global variables in your program. The main namespace is the module, which can contain global variables and functions. In addition, classes and modules have their own namespaces where they can keep their own internal variables.
Functions also have their own namespaces; they allow you to use the same variable name without conflict inside of your function as long as it doesn’t conflict with any other variable outside of it or within its parent class’s (or parent module’s) namespace. This is accomplished by making sure that every time you create a new function definition, it creates its own local scope for the duration of the execution of that function call (a little bit more on this later).
Finally, there are exceptions which also have their own namespace within which they look for handlers to deal with them appropriately when an exception occurs during runtime execution.
