python串行、并行迭代多个列表

# 串行
def iterlist1():
    from itertools import chain
    from random import randint
    list1 = [randint(0, 100) for _ in range(20)]
    list2 = [randint(0, 100) for _ in range(30)]
    list3 = [randint(0, 100) for _ in range(40)]
    list4 = [x for x in chain(list1, list2, list3) if x > 90]
    print(list4)

#并行
def iterlist():
    from random import randint
    list1 = [randint(0, 100) for _ in range(20)]
    list2 = [randint(0, 100) for _ in range(20)]
    list3 = [randint(0, 100) for _ in range(20)]
   
    # 方式一
    list22 = list()
    for s1, s2, s3 in zip(list1, list2, list3):
        list22.append(s1+s2+s3)
    print(list22)


    # 方式二
    list4 = [sum(s) for s in zip(list1, list2, list3)]
    print(list4)


    # 方式三
    # list5 = list(map(lambda s1, s2, s3: s1+s2+s3, list1, list2, list3))
    list5 = list(map(sum, zip(list1, list2, list3)))
    print(list5)
