1. delorean,用来处理时间的库
import datetime import pytz # 一般情况下,我们想表示时间的话 est = pytz.timezone("Asia/Shanghai") t = datetime.datetime.now(est) print(t) # 2018-07-30 23:06:21.563803+08:00 # 使用delorean from delorean import Delorean d = Delorean() t = d.shift("Asia/Shanghai") print(t) # Delorean(datetime=datetime.datetime(2018, 7, 30, 23, 6, 21, 607802), timezone=‘Asia/Shanghai‘) print(t.next_day(1)) # Delorean(datetime=datetime.datetime(2018, 7, 31, 23, 7, 40, 48419), timezone=‘Asia/Shanghai‘) print(t.next_day(-1)) # Delorean(datetime=datetime.datetime(2018, 7, 29, 23, 8, 1, 593950), timezone=‘Asia/Shanghai‘) # 下一个星期天 print(t.next_sunday()) # Delorean(datetime=datetime.datetime(2018, 8, 5, 23, 8, 56, 391465), timezone=‘Asia/Shanghai‘) # 下一个星期五 print(t.next_friday()) # Delorean(datetime=datetime.datetime(2018, 8, 3, 23, 8, 56, 391465), timezone=‘Asia/Shanghai‘) from delorean import stops import delorean for stop in stops(freq=delorean.HOURLY, count=10): print(stop) ‘‘‘ Delorean(datetime=datetime.datetime(2018, 7, 30, 15, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 16, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 17, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 18, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 19, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 20, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 21, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 22, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 30, 23, 11, 17), timezone=‘UTC‘) Delorean(datetime=datetime.datetime(2018, 7, 31, 0, 11, 17), timezone=‘UTC‘) ‘‘‘
2.prettybody
from prettytable import PrettyTable p = PrettyTable() p.field_names = ["name", "age", "gender", "husband"] p.add_row(["satori", 18, "f", "zgg"]) p.add_row(["mashiro", 18, "f", "zgg"]) p.add_row(["miku", 18, "f", "zgg"]) p.add_row(["matsuri", 18, "f", "zgg"]) print(p) ‘‘‘ +---------+-----+--------+---------+ | name | age | gender | husband | +---------+-----+--------+---------+ | satori | 18 | f | zgg | | mashiro | 18 | f | zgg | | miku | 18 | f | zgg | | matsuri | 18 | f | zgg | +---------+-----+--------+---------+ ‘‘‘ # 添加一列 p.add_column("anime", ["东方地灵殿", "樱花庄的宠物女孩", "初音未来", "sola"]) print(p) ‘‘‘ +---------+-----+--------+---------+------------------+ | name | age | gender | husband | anime | +---------+-----+--------+---------+------------------+ | satori | 18 | f | zgg | 东方地灵殿 | | mashiro | 18 | f | zgg | 樱花庄的宠物女孩 | | miku | 18 | f | zgg | 初音未来 | | matsuri | 18 | f | zgg | sola | +---------+-----+--------+---------+------------------+ ‘‘‘ # 获取表格 print(p.get_html_string()) ‘‘‘ <table> <tr> <th>name</th> <th>age</th> <th>gender</th> <th>husband</th> <th>anime</th> </tr> <tr> <td>satori</td> <td>18</td> <td>f</td> <td>zgg</td> <td>东方地灵殿</td> </tr> <tr> <td>mashiro</td> <td>18</td> <td>f</td> <td>zgg</td> <td>樱花庄的宠物女孩</td> </tr> <tr> <td>miku</td> <td>18</td> <td>f</td> <td>zgg</td> <td>初音未来</td> </tr> <tr> <td>matsuri</td> <td>18</td> <td>f</td> <td>zgg</td> <td>sola</td> </tr> </table> ‘‘‘ print(p.get_string()) ‘‘‘ +---------+-----+--------+---------+------------------+ | name | age | gender | husband | anime | +---------+-----+--------+---------+------------------+ | satori | 18 | f | zgg | 东方地灵殿 | | mashiro | 18 | f | zgg | 樱花庄的宠物女孩 | | miku | 18 | f | zgg | 初音未来 | | matsuri | 18 | f | zgg | sola | +---------+-----+--------+---------+------------------+ ‘‘‘ # 获取指定的列,指定的行 print(p.get_string(fields=["name", "anime"], start=0, end=4)) ‘‘‘ +---------+------------------+ | name | anime | +---------+------------------+ | satori | 东方地灵殿 | | mashiro | 樱花庄的宠物女孩 | | miku | 初音未来 | | matsuri | sola | +---------+------------------+ ‘‘‘
3.snowballstemmer
# 用来提取单词词干,支持15种语言 from snowballstemmer import EnglishStemmer print(EnglishStemmer().stemWord("love")) print(EnglishStemmer().stemWord("production")) print(EnglishStemmer().stemWord("affection")) print(EnglishStemmer().stemWord("gravity")) ‘‘‘ love product affect graviti ‘‘‘
4.wget,比较有用的库,可以用来下载图片
import wget url = "https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1532975831713&di=6add9fa41ac1a7ddbddcaa919d49c497&imgtype=0&src=http%3A%2F%2Fimage.uczzd.cn%2F6715434799472055716.jpeg%3Fid%3D0" # 参数一:url,下载的地址,参数二:out,输出的文件名或路径 wget.download(url=url, out=r"C:UsersAdministratorDesktopaaamatsuri.jpg")
当然输入一个普通的url,会将整个页面的html文本下载下来
5.fuzzywuzzy,用来做字符串的相似度
from fuzzywuzzy import fuzz from fuzzywuzzy import process print(fuzz.ratio("my name is satori", "my name is mashiro")) # 74,表示相似度是百分之74 print(fuzz.ratio("i love satori", "I love satori")) # 92,可见是区分大小写的 print(fuzz.ratio("i love satori", "I love satori!")) # 89 print(fuzz.partial_ratio("i love satori", "i love satori!!!!!")) # 100 # 两者对位置都敏感,但是ratio是属于全匹配。partial_ratio是搜索匹配,知道一方结束,后面的即使有也不会造成影响 print(fuzz.ratio("我永远喜欢古明地盆", "我永远喜欢古明地盆,多睡觉少操心")) # 72 print(fuzz.partial_ratio("我永远喜欢古明地盆", "我永远喜欢古明地盆,多睡觉少操心")) # 100
