没有报错，但是代码执行无结果，只出现：Process finished with exit code 0

import urllib.request,urllib.error
def main():
    baseurl="https://movie.douban.com/top250?start="
    datalist = getData(baseurl)
    savepath = ".\\豆瓣电影TOP250.xls"
    saveData(savepath)
    askURL("https://movie.douban.com/top250?start=")
def getData(baseurl):
    datalist = []
    for i in range(0,10):
        url = baseurl +str(i*25)
        html = askURL(url)
    return datalist
def askURL(url):
    head = {
        "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0"
         }
    request = urllib.request.Request(url,headers=head)
    html = ""
    try:
        response = urllib.request.urlopen(request)
        html = response.read().decode("utf-8")
        print(html)
    except urllib.error.URLError as e:
        if hasattr(e,"code"):
            print(e.code)
        if hasattr(e,"reason"):
            print(e.reason)
    return html
def saveData(savepath):
    print(html)

Process finished with exit code 0

尝试过Try 解析不显示原因，也是显示Process finished with exit code 0

是否可以调试一下，我目前在学习爬取网页内容

没有报错，最后一个函数写错了，是不是编译器原因没报错，有问题的我帮你改好了，看看注释

import urllib.request, urllib.error


def main():
    baseurl = "https://movie.douban.com/top250?start="
    datalist = getData(baseurl)
    savepath = ".\\豆瓣电影TOP250.xls"
    html = askURL("https://movie.douban.com/top250?start=")  # 获取返回参数
    saveData(savepath, html)


def getData(baseurl):
    datalist = []
    for i in range(0, 10):
        url = baseurl + str(i * 25)
        html = askURL(url)
    return datalist


def askURL(url):
    head = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0"
    }
    request = urllib.request.Request(url, headers=head)
    html = ""
    try:
        response = urllib.request.urlopen(request)
        html = response.read().decode("utf-8")
        print(html)
    except urllib.error.URLError as e:
        if hasattr(e, "code"):
            print(e.code)
        if hasattr(e, "reason"):
            print(e.reason)
    return html


def saveData(savepath, html):  # 加入html参数进传参，不然saveData函数无法访问到html，当然也可以使用global将其设为全局变量
    print(html)  # 不过不推荐


main()  # 调用函数才可以执行
