Subtratcting a blank from a sample/ raman spec

enter image description here

Hello!

I have two sets of data, orange is the blank and the blue is the actual sample which contains the blank signal as well. I am not quite familiar with python. I am trying to subtract the blank from the sample to isolate the important peaks in the same. I was able to align the blank with the sample, but unsure how to do the subtraction. Any ideas on how to do that or websites I could use?
