# sorted()函数list进行排序: L = sorted([36, 5, -12, 9, -21]) print(L) # [-21, -12, 5, 9, 36] # 可以看到默认是按照升序排 LL = sorted([36, 5, -12, 9, -21], key=abs) print(LL) # [5, 9, -12, -21, 36] 自定义key 按照绝对值进行排序 lstr = sorted(['bob', 'about', 'Zoo', 'Credit']) print(lstr) # ['Credit', 'Zoo', 'about', 'bob'] 默认按照ASCII的大小排序 lsortlower = sorted(['bob', 'about', 'Zoo', 'Credit'], key=str.lower) print(lsortlower) # ['about', 'bob', 'Credit', 'Zoo'] lsortlowerRev = sorted(['bob', 'about', 'Zoo', 'Credit'], key=str.lower, reverse=True) print(lsortlowerRev) # ['Zoo', 'Credit', 'bob', 'about'] 按照原有规则反向排序
