python_如何在一个for循环中迭代多个可迭代对象?

#!/usr/bin/python3

from random import randint


def get_result(chinese, math, english):
    total = []
    # 循环索引进行取值，毕竟列表等长且成绩对应
    for index in range(len(chinese)):
        total.append(chinese[index] + math[index] + english[index])
    return total

if __name__ == ‘__main__‘:
    # 生成 3 个成绩列表
    chinese = [randint(60, 100) for _ in range(40)]
    math = [randint(60, 100) for _ in range(40)]
    english = [randint(60, 100) for _ in range(40)]
    
    # 统计 总成绩
    total = get_result(chinese, math, english)
    
    for x in total:
        print(x)

#!/usr/bin/python3

from random import randint


def get_result(chinese, math, english):
    total = []
    # 通过zip函数进行迭代，实现同时迭代 3 个对象
    for c, m, e in zip(chinese, math, english):
        print(c, m, e)
        total.append(c + m + e)
    return total

if __name__ == ‘__main__‘:
    # 生成 3 个成绩列表
    chinese = [randint(60, 100) for _ in range(40)]
    math = [randint(60, 100) for _ in range(40)]
    english = [randint(60, 100) for _ in range(40)]
    
    # 统计 总成绩
    total = get_result(chinese, math, english)
    
    for x in total:
        print(x)

#!/usr/bin/python3

from random import randint
from itertools import chain


def get_result(e1, e2, e3):
    # 通过chain函数进行连续窜行迭代3个列表
    for i in chain(e1, e2, e3):
        print(i)

if __name__ == ‘__main__‘:
    # 生成 3 个班成绩单，1班36人，2班43人，3班40人
    e1 = [randint(60, 100) for _ in range(36)]
    e2 = [randint(60, 100) for _ in range(43)]
    e3 = [randint(60, 100) for _ in range(40)]
    
    # 依次打印成绩
    get_result(e1, e2, e3)
