如何在python中将嵌套循环转换为列表解析

Question

如何将此代码转换为python中的列表理解

max_len = []
for word in fourier_dict:
    word = fourier_dict[word]
    for occur in word:
        max_len.append(len(occur))

我是python的新手,我必须将这个嵌套循环转换为列表理解,我无法弄清楚.一点帮助将非常感激.

Answer 1

max_len = [len(occur) for word in fourier_dict for occur in fourier_dict[word]]

应该管用.
