如何使这成为列表理解

Question

我如何将其写为列表理解？

for i in range(len(genes)):
    if compareGenes(genes[i], target) > count:
        best = genes[i]
        count = compareGenes(genes[i], target) 

Answer 1

max 使用生成器理解将是一个很好的方法.

count, best = max((compareGenes(k, target), k) for k in genes)

或者,使用key参数max:

best = max(genes, key=lambda k: compareGenes(k, target))
