What can you do with NumPy?
Quite understandably, NumPy contains a large number of various mathematical operations. NumPy provides standard trigonometric functions, functions for arithmetic operations, handling complex numbers, etc. NumPy has standard trigonometric functions which return trigonometric ratios for a given angle in radians.
How to import NumPy in Python?
This import is like any python package import. To use the functions of numpy, the package has to be imported at the start of the program. The syntax of importing numpy package is: Python community usally uses the numpy package with an alias np. Now, you can use np to call all numpy functions.
How to make a NumPy array in Python?
To make a numpy array, you can just use the np.array() function. All you need to do is pass a list to it, and optionally, you can also specify the data type of the data. If you want to know more about the possible data types that you can pick, go here or consider taking a brief look at DataCamp’s NumPy cheat sheet.
