In this example, we have concatenated two 1-D arrays vertically to create a 2-D array. This isn’t possible using the concatenate() function. While concatenating 1-D numpy arrays using the vstack() function, you need to make sure that all the arrays have equal lengths. Otherwise, the pr...
We can plot the data using the normal KDE plot function with the Seaborn library. In the following example, we have created 1000 data samples using the random library then arranged them in the array ofnumpybecause the Seaborn library only works well withnumpyand Pandasdataframes. ...
