如何簡化這個糟糕的代碼？

Question

我是編程新手，在簡化代碼方面遇到一些問題。 我之前的部分沒有問題，只需要知道如何簡化此代碼即可。 我希望下面的代碼在“ 11”的位置也繪制出12,18,20,27和28。 我將不勝感激！

Answer 1

無論no1 - no30是什么，您都需要將其放入序列對象（如list ，然后在該序列對象上循環以產生輸出，您也將其放入序列對象中（在這種情況下，我認為dict將最好）。

nos = [no1, no2, ..., no30]
simrecno_inds11 = {}
recno_inds11 = {}
exclude_nums = [6]
for k, no in enumerate(nos):
    if k in exclude_nums:
        continue
    simrecno_inds11[k] = nonzero(datasim11[:,1]==no)[0]
    recno28inds11[k] = nonzero(data11[:,1]==no)[0]

現在，代替訪問simrecno17inds11 ，您將訪問simrecno_inds11[17] ，依此類推。

Answer 2

看來您的“ simrecnoXXindsYY”變量可以用二維數組simrec[n, i] （n-> no，i-> inds）。 以同樣的方式，“ recnoXXindsYY”可以變成rec[n,i] 。 最后，“ noXX”可以是一維數組no[n] 。 因此，您的作業具有以下形式：

simrec[n, i] = nonzero(datasim[i][:,1]==no[n])[0]
rec[n, i] = nonzero(data[i][:,1]==no[n])[0]

因此，您需要為n （nos）和i （index）的所有可能值循環。

indexes = [11, 12, 18, 20, 27, 28]
nos = range(1,31)

for i in index:
    for n in nos:
        simrec[n, i] = nonzero(datasim[i][:,1]==no[n])[0]
        rec[n, i] = nonzero(data[i][:,1]==no[n])[0]
