The numpy.ones() function is used to create a new array of given shape and type, filled with ones. The ones() function is useful in situations where we need to create an array of ones with a specific shape and data type, for example in matrix operations or in initializing an array wi...

You can initialize arrays with ones or zeros, but you can also create arrays that get filled up with evenly spaced values, constant or random values. However, you can still make a totally empty array, too. Luckily for us, there are quite a lot of functions to make. Try it all out ...
