# Add Numpy array into other Numpy array

Hi experts!!

My code starts with a empty array (POPOPO=np.array([])).

In the next lines, np.array are created (L1, L2, ...). How can it add this new-created-arrays into POPOPO in order to obtain the array POPOPO= [[L1],[L2],...]? Its important to note that L1, L2,.... have different lenght.

Waiting for your answers.

Thanks in advance!

Hello mresimulator, what type of arrays are the L1, L2,.. are they one-dimensional? btw, did you solve the problem already?

what did you tried so far to fill the POPOPO array?
