Lobotus Technology Python Developer Interview Questions and Answers

List is a collection of ordered and changeable elements.

• Lists are created using square brackets []

• Elements in a list can be of different data types

• Lists can be sliced and concatenated

• Example: my_list = [1, 'apple', True, 3.14]

Lists are mutable and can be modified, while tuples are immutable and cannot be modified.

• Lists are enclosed in square brackets [], while tuples are enclosed in parentheses ().

• Lists can have elements of different data types, while tuples can have elements of the same or different data types.

• Lists have more built-in methods for manipulation, such as append(), remove(), and sort().

• Tuples are generally used for heterogeneo...read more

A dictionary is a collection of key-value pairs, where each key is unique and used to access its corresponding value.

• Keys must be immutable objects like strings, numbers, or tuples.

• Values can be any type of object, including other dictionaries.

• Dictionaries are unordered, meaning the order of items is not guaranteed.

• Accessing a value using a key is fast and efficient.

• Example: {'name': 'John', 'age': 30, 'city': 'New Yor

To get the value for a key from a dictionary in Python, use the square bracket notation or the get() method.

• Use square brackets and the key name to access the value directly: dictionary[key]

• Alternatively, use the get() method to retrieve the value: dictionary.get(key)

• If the key is not present in the dictionary, using square brackets will raise a KeyError, while get() will return None or a default value if specified

Memory management is the process of allocating and deallocating memory in a computer system.

• Memory is allocated dynamically using malloc() or new() functions.

• Memory leaks occur when memory is not deallocated after use.

• Garbage collection is used in languages like Python to automatically deallocate memory.

• Memory fragmentation can occur when memory is allocated and deallocated frequently.

• Memory management is important for

RestAPI is a web service that uses HTTP requests to access and manipulate data.

• RestAPI stands for Representational State Transfer Application Programming Interface.

• It is a standard protocol used for creating web services.

• It uses HTTP methods like GET, POST, PUT, DELETE to perform operations on data.

• It returns data in various formats like JSON, XML, etc.

• Examples of RestAPIs include Twitter API, Facebook API, etc.
