Below are the examples of how to create or initialize the array with nan values in Python programs. Example #1 We can create nan using float data type and can found in the math module also but only in the Python 3.5 plus version. ...
Thenumpy.full()function in NumPy is used to create an array with a specified shape and fill it with a constant value. Its primary purpose is to initialize an array where all elements have the same predetermined value. Can I create a 1-D array using numpy.full()?
