Associate Programmer Analyst Interview Questions and Answers

Lists are mutable and ordered, while tuples are immutable and ordered collections in Python.

• Mutability: Lists can be modified (e.g., list.append(1)), while tuples cannot (e.g., tuple[0] = 1 raises an error).

• Syntax: Lists use square brackets [] (e.g., myList = [1, 2, 3]), while tuples use parentheses () (e.g., myTuple = (1, 2, 3)).

• Performance: Tuples are generally faster than lists for iteration due to their immutability.

• Use Cases: Lists are used for collections of items that ...read more

Adding two variables involves summing their values to produce a new result, often used in programming and calculations.

• Variables can hold different data types, such as integers or floats. Example: int a = 5; int b = 10; int sum = a + b;

• In programming, addition can be performed using the '+' operator. Example: float x = 2.5; float y = 3.5; float total = x + y;

• When adding arrays, you may need to iterate through elements. Example: for (int i = 0; i < array.length; i++) { sum += ...read more
