但是?。?！

我沒沒沒有xcode!!!

……

……

………………

所以很不爽，于是我就弄了一個不需要xcode的實用小程序（基本上就是翻新了一下）

第一個：天氣預報

需要的組件：urllib,requests,beautifuisoup4(import時寫作bs4),xpinyin

都可以通過pip安裝：pip install urllib requests beautifuisoup4 xpinyin

代碼：

import urllib,requests,xpinyin#導入urllib,requests,正則表達式,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  # 返回結果


pinyin = xpinyin.Pinyin()
m = input('要查詢的天氣')
tianqi_pinyin = pinyin.get_pinyin(m,'') 
print(get_weather(tianqi_pinyin))

第二個：穿衣指南

需要的庫和上面一樣

都用了get_weather函數（就是上一個再拿正則表達式找一下溫度字符串）

代碼：

import urllib,requests,xpinyin,re#導入urllib,requests,正則表達式,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  # 返回結果


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

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

if m >= 30:
    print('需要短袖T恤')
elif m <= 5:
    print('需要羽絨服絨褲')
else:
    print('需要長袖長褲')

庫都是一樣的（水一下）

代碼：

import urllib,requests,xpinyin,re#導入urllib,requests,正則表達式,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  # 返回結果


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

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

if m >= 30:
    print('需要防暑')
elif m <= 15:
    print('需要防凍')
else:
    print('天氣合適')

4.計算器

這個啥庫都不需要

代碼：

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

這就是這篇拙作的內容啦
