Senior Python Developer interview questions and answers Workable

It returns the list of all the words present in the string. All of the Python is an object and all variables hold references to the object. The reference values are according to the functions; as a result, the value of the reference cannot be changed. The map() function applies a given function to each item of an iterable.

  • Just like it copies the values, the shallow copy also copies the reference pointers.
  • Python is used in several areas such as web development, GUI applications, web scraping, automation, data science, machine learning, and more.
  • Make sure to do your coding practice and work on the development part.
  • Understand object-based concepts such as classes, methods, overloading, and inheritance.
  • Structured and functional programming is supported.

Docstring phrase ends with a period (.) and can be multiple lines. It may consist of spaces and other special chars. A namespace is defined as a simple system to control the names in a program. It ensures that names are unique and won’t lead to any conflict. Python uses a rich set of operators to perform a variety of operations. Some individual operators like membership and identity operators are not so familiar but allow to perform operations.

Explain While loop in Python with example

You then append their actual grades to that student’s list of grades. Pretend you have a group of students, and you need to keep track of their grades on homework assignments. The input value is a list of tuples with the format , but you want to easily look up all the grades for a single student without iterating over the list. This approach isn’t terrible, but it unnecessarily creates a list and then converts it to a set. Interviewers almost always notice this type of design choice. You’re supposed to call get_random_word() repeatedly to get 1000 random words and then return a data structure containing every unique word.

What is * a in Python?

The asterisk (star) operator is used in Python with more than one meaning attached to it. For numeric data types, * is used as multiplication operator >>> a=10;b=20 >>> a*b 200 >>> a=1.5; b=2.5; >>> a*b 3.75 >>> a=2+3j; b=3+2j >>> a*b 13j.

It was designed with an emphasis on code readability, and its syntax allows programmers to express their concepts in fewer how to become a python developer lines of code. Python works great for data analysis especially for data mining, data processing and data visualization.

What are the types of literals in Python?

While searching for the object, the key, which corresponds to the unique name, is mapped with the value assigned to the related object.. Python has its namespace maintained like a Python dictionary. Set of questions are given below for you to know more about it. Get it done to get stronger in python programming language.

Python is considered to be a multi-paradigm language, which means it supports multiple programming techniques including object-oriented and functional programming. Since most Python tools have bundled up data and functions, it is considered to be object-oriented. The functions of Python are important for data scientists and programmers alike because Python supports both object-oriented and functional programming. A) Memory management in Python involves a private heap containing all Python objects and data structures.

Explain how memcached should not be used in your Python project?

Python Program to print all even numbers in array. Python Program to delete element from array at given index. Python program to insert element at a given location in Array. Python program to insert an element at end of an Array. Python program to find top two maximum number in array. Write a program in Python to find second highest number in an integer array.
