但是！！！

我没没没有xcode!!!

……

……

………………

所以很不爽，于是我就弄了一个不需要xcode的实用小程序（基本上就是翻新了一下）

第一个：天气预报

需要的组件：urllib,requests,beautifuisoup4(import时写作bs4),xpinyin

都可以通过pip安装：pip install urllib requests beautifuisoup4 xpinyin

代码：

import urllib,requests,xpinyin#导入urllib,requests,正则表达式,xpinyin和beautifulsoup4
from bs4 import BeautifulSoup 


def get_weather(city_pinyin):
    header = {
        "User-Agent": "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.87 Safari/537.36"}
    website = "https://www.tianqi.com/" + city_pinyin + "/"
    req = urllib.request.Request(url=website, headers=header)
    page = urllib.request.urlopen(req)
    html = page.read()
    soup = BeautifulSoup(html.decode("utf-8"), "html.parser")
    nodes = soup.find_all('dd')
    tody_weather = [node.text.strip() for node in nodes]  
    tody_weather[0] = tody_weather[0][:2] 
    tianqi = " ".join([s for s in tody_weather if s.strip("\n")])
    return tianqi  # 返回结果


pinyin = xpinyin.Pinyin()
m = input('要查询的天气')
tianqi_pinyin = pinyin.get_pinyin(m,'') 
print(get_weather(tianqi_pinyin))

第二个：穿衣指南

需要的库和上面一样

都用了get_weather函数（就是上一个再拿正则表达式找一下温度字符串）

代码：

import urllib,requests,xpinyin,re#导入urllib,requests,正则表达式,xpinyin和beautifulsoup4
from bs4 import BeautifulSoup 


def get_weather(city_pinyin):
    header = {
        "User-Agent": "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.87 Safari/537.36"}
    website = "https://www.tianqi.com/" + city_pinyin + "/"
    req = urllib.request.Request(url=website, headers=header)
    page = urllib.request.urlopen(req)
    html = page.read()
    soup = BeautifulSoup(html.decode("utf-8"), "html.parser")
    nodes = soup.find_all('dd')
    tody_weather = [node.text.strip() for node in nodes]  
    tody_weather[0] = tody_weather[0][:2] 
    tianqi = " ".join([s for s in tody_weather if s.strip("\n")])
    return tianqi  # 返回结果


wenduRegex = re.compile(r'(\S)+℃')
pinyin = xpinyin.Pinyin()
m = input('穿衣查询\n你在哪个城市:')
tianqi_pinyin = pinyin.get_pinyin(m,'') 
weather = get_weather(tianqi_pinyin)

m = wenduRegex.search(weather)
m = m.group()
print(f'温度:{m}')
m = int(m[:-1])

if m >= 30:
    print('需要短袖T恤')
elif m <= 5:
    print('需要羽绒服绒裤')
else:
    print('需要长袖长裤')

库都是一样的（水一下）

代码：

import urllib,requests,xpinyin,re#导入urllib,requests,正则表达式,xpinyin和beautifulsoup4
from bs4 import BeautifulSoup 


def get_weather(city_pinyin):
    header = {
        "User-Agent": "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.87 Safari/537.36"}
    website = "https://www.tianqi.com/" + city_pinyin + "/"
    req = urllib.request.Request(url=website, headers=header)
    page = urllib.request.urlopen(req)
    html = page.read()
    soup = BeautifulSoup(html.decode("utf-8"), "html.parser")
    nodes = soup.find_all('dd')
    tody_weather = [node.text.strip() for node in nodes]  
    tody_weather[0] = tody_weather[0][:2] 
    tianqi = " ".join([s for s in tody_weather if s.strip("\n")])
    return tianqi  # 返回结果


wenduRegex = re.compile(r'(\S)+℃')
pinyin = xpinyin.Pinyin()
m = input('穿衣查询\n你在哪个城市:')
tianqi_pinyin = pinyin.get_pinyin(m,'') 
weather = get_weather(tianqi_pinyin)

m = wenduRegex.search(weather)
m = m.group()
print(f'温度:{m}')
m = int(m[:-1])

if m >= 30:
    print('需要防暑')
elif m <= 15:
    print('需要防冻')
else:
    print('天气合适')

4.计算器

这个啥库都不需要

代码：

print('计算器Calculator')
while True:
    try:
        print('请输入算式，按下Ctrl-C退出')
        print(eval(input()))
    except KeyboardInterrupt:
        print('Exit')
        break

这就是这篇拙作的内容啦
