BonjourI have three lists with 65 float items and would like to do the following sum: L0 = ([sum(L0A[i]*cos(L0B[i]+L0C[i]*JME) for i in range(0,64,1))]) So it just should do a sum across all the items in the list: L0A[0]*cos(L0B[0]+L0C[0]*JME)+ L0A[1]*cos(L0B[1]+L0C[1]*JME)+... + L0A[64]*cos(L0B[64]+L0C[64]*JME)= some float number However, I always get this error: TypeError: can't multiply sequence by non-int of type 'float' I looked it up and there seems to be some solution using either the "for-in" command or the "map(int,...)" command but I just can't get it to work.... Any help will be very much appreciated :) Greetings from Sydney Chris
Surely it should be L0 = sum([(L0A[i]*cos(L0B[i]+L0C[i]*JME) for i in range(0, 64)]) as you want to generate the answers and then sum it up. -- Kind Regards, Christian Witts _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
