Calculate in Python

Question

is there are way to write this more comfortable in python?

quote_e[i] = [i, (1 * o +
 2 * p +
 3 * q +
 4 * r +
 5 * s +
 6 * t +
 7 * u +
 8 * v +
 9 * w +
 10 * x +
 11 * y +
 12 * z) / 78]

The variables are from a list that was created before.

o = ema_12[i - 12][1]
 p = ema_12[i - 11][1]
 q = ema_12[i - 10][1]
 r = ema_12[i - 9][1]
 s = ema_12[i - 8][1]
 t = ema_12[i - 7][1]
 u = ema_12[i - 6][1]
 v = ema_12[i - 5][1]
 w = ema_12[i - 4][1]
 x = ema_12[i - 3][1]
 y = ema_12[i - 2][1]
 z = ema_12[i - 1][1]

Thanks in advance.

• kingkupps: Could you please explain more specifically what you mean by "more comfortable"?
• Thierry Lathuille: What are all these variables? Where do they come from? We don't know, we can't help. Just a guess: maybe you should use a list rather than all of there unrelated variables?
• Dan Ru: Hi kingkupps. Sure. I meant that I think, that there could be a way to write it shorter. More efficient. Something like letters (uprising) * numbers (uprising). I hope that describes it better.
• Dan Ru: Hi, Thierry. The variables are from a list. o = ema_12[i - 12][1] p = ema_12[i - 11][1] q = ema_12[i - 10][1] r = ema_12[i - 9][1] s = ema_12[i - 8][1] t = ema_12[i - 7][1] u = ema_12[i - 6][1] v = ema_12[i - 5][1] w = ema_12[i - 4][1] x = ema_12[i - 3][1] y = ema_12[i - 2][1] z = ema_12[i - 1][1]
• Thierry Lathuille: Please edit your question to include all relevant information - as you can see, code in comments is pretty unreadable...

Answer 1

var_list =[ ema_12[i-j][1] for j in range(12,0,-1) ]
quote_e[i]=[i,(np.arange(1,13)*var_list)/78]

This creates your list of variable o to z.Here muliplication will be element-wise

I hope this is what you required

• Dan Ru: Thank you very much. That was what I was looking for.
