Test: Starting with Python - 1 - Software Development MCQ

Python is a strongly typed language, meaning that variables have specific types, and their types cannot be changed implicitly.

Python modules are used to organize and reuse code. They allow you to create reusable code libraries that can be imported into other programs.

In Python, a variable is defined by assigning a value to it using the equal sign (=).

Lists are mutable in Python, meaning that their elements can be modified.

The code performs floating-point division (x / y), which results in 2.5.

According to the order of operations, multiplication is performed before addition. So, 4 * 2 is evaluated first, resulting in 8, and then 3 + 8 is evaluated, resulting in 11.

Python does not support C-style comments (/ comment */). Python uses the pound sign (#) to indicate single-line comments.

The if statement is used in Python to make decisions based on conditions. It allows you to execute certain code blocks only if a certain condition is true.

The fourth option has an incorrect combination of single and double quotes. In Python, a string should be enclosed in either single quotes ('') or double quotes ("").

Arrays are not built-in data types in Python. However, Python provides lists, which can be used as dynamic arrays.

The code adds the values of x and y (10 + 5) and prints the result, which is 15.

The code concatenates the values of x, a space, and y and prints the result, which is "Hello World".

The code performs the modulus operation (x % y), which gives the remainder when x is divided by y. In this case, 5 divided by 2 leaves a remainder of 1.

The code appends the value 4 to the list x, and then prints the length of the list using the len() function, which is 4.

The code converts the tuple x to a list y using the list() function, and then prints the element at index 1 of y, which is 2.

The code performs floating-point division (x / y), which results in 2.5.

The code uses slicing to extract the substring from index 7 to index 12 (exclusive) from the string x, which is "World".

The code removes the element 2 from the list x using the remove() method, resulting in [1, 3].

The code concatenates the list x with the list [4, 5] using the + operator, resulting in [1, 2, 3, 4, 5].

The code uses slicing to create a new tuple y containing the elements from index 1 to the end of the tuple x, which is (2, 3).
