CBSE Class 11 - Informatics Practices - Python Basics - Numpy Arrays (Part-1) - Question and Answers (#CBSEclass11Python)(#cbse)(#eduvictors)

Q1: What is NumPy?

Answer
1. NumPy stands for Numerical Python.

2. It is the core library for scientific computing in Python.

3. A NumPy array (also called ndarray) is a homogeneous multidimensional array of data objects.

4. A NumPy array is a table of elements (usually numbers), all of the same type, indexed by a tuple of positive integers.

5. Numpy module provides a set of methods and tools for working with these arrays.

6. In Numpy dimensions are called axes. The number of axes is rank.


Q2: What is the command line option to install NumPy module?

Answer: Run the following command at the command prompt. 
pip install numpy


Q3: What is one dimensional (1D) array?

Answer: A one-dimensional array or 1D array is a named group of a contiguous set of elements having the same data type. 1D arrays are also called vectors.

Q4: What is a multi-dimensional array?

Answer: A multidimensional array is an array of arrays. Multi-dimensional arrays are also known as matrices. For example, a two-dimensional array (2D array) has two axes i.e. rows and columns.

CBSE Class 11 - Informatics Practices - Python Snippets -1 (Arithmetic Operators) (#cbsenotes)(#eduvictors)

Python Snippets - 1(Arithmetic Operators)

CBSE Class 11 - Informatics Practices - Python Snippets -1 (Arithmetic Operators) (#cbsenotes)(#eduvictors)

Arithmetic operators are used with numeric values to perform mathematical operations. Python supports the following arithmetic operators

+   Addition: To add two numbers i.e. a + b
-   Subtraction: To find difference of two numbers i.e. a - b
*   Multiplication: Product of two numbers e.g. 2 × 3 = 6
/   Division: To find quotient in division i.e. returning the floating-point result of the computation
%   Modulus: To remainder in division method
//  Floor Division or Intger Division i.e. rounds the result down to the nearest whole number
**  Exponentiation e.g. find 12² = 144

The above said are also called binary arithmetic operator because it requires two operands.
