Np.concatenate axis 0
WebJoining NumPy Arrays. Joining means putting contents of two or more arrays in a single array. In SQL we join tables based on a key, whereas in NumPy we join arrays by axes. We pass a sequence of arrays that we want to join to the concatenate () function, along with the axis. If axis is not explicitly passed, it is taken as 0.
