Instead of data structure, a particular range can also be defined here using the range() method of Python. To view all the key values stored in the Dictionary, the key() method is used. It returns a view that contains information of all the keys stored in a particular dictionary. Set is generally mutable, but there is a special type of Set, i.e., Frozen Set, an immutable data structure. A tuple is one of the data structures that are immutable, and its values can’t be changed.
- So, for instance, if the parent class has a method named ABC then the child class also can have a method with the same name ABC having its own parameters and variables.
- A list is a mutable data structure, meaning that you can modify its contents by adding, removing, or changing elements after it has been created.
- Diving into your problem-solving skills is essential for interviewers when hiring a Python developer.
- Whereas, javadoc is removed from the bytecode and it is not present in .class file.
At Bridge, we work with local recruiters who understand technology and software development processes and speak with candidates in their native tongue. Having assessed developers’ skills, recruiters provide you with a list of viable candidates to interview and hire the most suitable one. On the other hand, OOP is class-focused, allowing developers to create variables that can be manipulated using methods or functions, inherited, or extended. Being enthusiastic is a key factor that will significantly impact your interview results. Brush up on all the common interview concepts before practising various Python interview questions and answers. Inheritance allows one class to gain all the members(say attributes and methods) of another class.

Questions here could cover topics such as ORM (Object-Relational Mapping), database migrations, and query optimization. An index offers an efficient way to quickly access the records from the database files stored. Indexing is the process of creating a data structure that improves the speed of data retrieval operations on a database. ORM enhances security by reducing the risk of SQL injection attacks, since developers are not manually constructing query strings. ORM simplifies database operations in Python applications, making them more efficient and secure. Graph is a network consisting of nodes connected by edges or arcs.
If you need a recommendation, I suggest going through 100 Days of Code — The Complete Python Pro Bootcamp by Angela Yu on Udemy. Functional programming relies on the concept of function, using inputs in computations to return the desired output. It facilitates managing a file stream and improves code readability – for example, there’s no need to call file.close() how to become a python developer when using with. Thus, while there’s an illusion of parallelism (multiple strings running synchronously), the truth is, threads take turns during execution. However, the process is so fast that it’s barely distinguishable to the human eye. If something about the question confuses you or isn’t clear, it can be helpful to inquire further via additional questioning.
“How do you handle version control and collaborative coding in Python projects?”
The `threading` module provides a way to create and manage threads in Python, allowing you to write concurrent programs. The `multiprocessing` module provides a way to create and manage processes in Python, allowing you to write parallel programs that can take advantage of multiple CPU cores. The `pickle` module is used for serializing and deserializing Python objects, allowing you to save and load objects to and from disk. The `pickle` module provides the `dump()` and `load()` functions for writing and reading pickled objects, respectively. The `__call__` method is a special method in Python that allows an object to be called as a function.
These questions go beyond the basics and get to the heart of Python development skills, real-world experiences, and how candidates approach coding challenges. We believe this resource will make life easier for hiring managers like you and give job seekers a clearer picture of what it takes to be a Senior Python developer. Conducting interviews that really help you figure out if a candidate is up to the job can be just as tricky. Our experience and data show that finding the right interview questions to spot a top-notch Senior Python developer is no walk in the park.
