如何在这段代码中创建三个函数以使它们都起作用？

  • 772

  1. 我需要两个函数 my_parse_eng 和 my_parse_rus 来解析站点，这没有问题。然后我不知道如何将接收到的数据发送到 my_open(): 函数，该函数将所有内容写入 text.csv 文件

  2. 在main函数中，我两次访问同一个链接，如何正常访问，不重复？

import requests
from lxml import etree
import lxml.html
import csv

def my_open():
    with open("text.csv", "w", newline='') as csv_file:
        write = csv.writer(csv_file)
    for i in range(len(my_parse_eng())):
        write.writerow(my_parse_eng([i]))
        write.writerow(my_parse_rus([i]))  

def my_parse_eng(url):
    api = requests.get(url)
    tree = lxml.html.document_fromstring(api.text)
    text_original = tree.xpath('//*[@id="click_area"]//*[@class="original"]/text()')
    return(text_original)

def my_parse_rus(url):
    api = requests.get(url)
    tree = lxml.html.document_fromstring(api.text)
    text_translate = tree.xpath('//*[@id="click_area"]//*[@class="translate"]/text()')
    return(text_translate)
    
def main():
    my_parse_eng("https://www.amalgama-lab.com/songs/t/tones_and_i/dance_monkey.html")
    my_parse_rus("https://www.amalgama-lab.com/songs/t/tones_and_i/dance_monkey.html")
    my_open()
    
if __name__ == "__main__":
    main()
python

    您main从函数中获取数据，将其保存到变量中，然后通过参数将其传递给my_open：

    def my_open(eng, rus):
    with open("text.csv", "w", newline='') as csv_file:
        write = csv.writer(csv_file)

        for e, r in zip(eng, rus):
            write.writerow([e])
            write.writerow([r])
            # Вообще, логично было бы писать оригинал и перевод в одну строку в разные колонки:
            # write.writerow([e, r])


...  # Функции my_parse_eng, my_parse_rus без изменений


def main():
    url = "https://www.amalgama-lab.com/songs/t/tones_and_i/dance_monkey.html"
    eng = my_parse_eng(url)
    rus = my_parse_rus(url)
    my_open(eng, rus)
