What is NumPy?

Numpy is one of the most widely used libraries in Python. Provides functions that allow developers to perform basic and advanced mathematical and statistical functions in multidimensional arrays, and matrixwith fewer lines of code. The 'ndarray' or n-dimensional array data structure is the main function of Numpy. These arrays are homogeneous and all elements of the array must be of the same type.

NumPy arrays are faster than Python strings. However, python strings are more flexible than numpy arrays because you can store only the same data type on each column.


  • A combination of C and python
  • Multidimensional homogeneous sequences. Ndarray is a sizable array
  • Various functions for arrays.

Why Use it?

  1. Less memory usage
  2. Fast performance
  3. Suitable for Work


  • Numpy arrays take up less space.

NumPy arrays are smaller in size than Python strings. A python string can take 20 MB in size, while you can get a series of 4 MB. Arrays are also easily accessible for reading and writing.

  • Speed performance is also great. Python calculates faster in strings.

Because it is open source, it uses Python, a very popular programming language with high quality libraries, and has high quality libraries for almost every task. It is also easy to link the existing C code to the Python interpreter.
