x=input("请输入一个整数")
s=x%2
if s==0:
print("{}是偶数。".format(s))
else:
print("{}是奇数。".format(s))
input函数接收到的数据默认都是字符串类型的,转换一下x=int(input("请输入一个整数"))
有帮助的话,请点采纳该答案~
x=input("请输入一个整数")
s= int(x)%2
if s==0:
print("{}是偶数。".format(x))
else:
print("{}是奇数。".format(x))
首先快速的导入我们需要的模块,我把相同的表情都放在了同一个文件夹下面,所以需要导入 os
模块
import asyncio import aiohttp from lxml import etree import os
编写主要的入口方法
headers = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36"}
async def get_face(url):
print("正在操作{}".format(url))
async with aiohttp.ClientSession() as s:
async with s.get(url,headers=headers,timeout=5) as res:
if res.status==200:
html = await res.text()
html_format = etree.HTML(html)
hrefs = html_format.xpath("//a[@class='list-group-item random_list']")
for link in hrefs:
url = link.get("href")
title = link.xpath("div[@class='random_title']/text()")[0] # 获取文件头部
path = './biaoqings/{}'.format(title.strip()) # 硬编码了,你要先在项目根目录创建一个biaoqings的文件夹
if not os.path.exists(path):
os.mkdir(path)
else:
pass
async with s.get(url, headers=headers, timeout=3) as res:
if res.status == 200:
new_html = await res.text()
new_html_format = etree.HTML(new_html)
imgs = new_html_format.xpath("//div[@class='artile_des']")
for img in imgs:
try:
img = img.xpath("table//img")[0]
img_down_url = img.get("src")
img_title = img.get("alt")
except Exception as e:
print(e)
async with s.get(img_down_url, timeout=3) as res:
img_data = await res.read()
try:
with open("{}/{}.{}".format(path,img_title.replace('\r\n',""),img_down_url.split('.')[-1]),"wb+") as file:
file.write(img_data)
except Exception as e:
print(e)
else:
pass
else:
print("网页访问失败")
就这样,海量表情包快到碗里来。
需要斗图的小伙伴自己动手试试吧~
