Numpy.save() - GeeksforGeeks, numpy.save () numpy.save () function is used to store the input array in a disk file with npy extension (.npy). Syntax : numpy.save (file, arr, allow_pickle=True, fix_imports=True) file : : File or filename to which the data is saved. If file ...
Where the condition is not satisfied (for the elements 5 and 15), the value Low is returned. Usingnumpy.where, we replace all non-matched numbers with the string ‘Low’ and all matched numbers with the string ‘High’. Return values ...
We can also create a DataFrame by implementing the numpy.zeros(). Such ndarrays will have all zero values and will use the same for creating the DataFrame also. Here is a code snippet showing how to implement it. import numpy as np ...
