本篇内容介绍了“如何用Pyecharts生成云词”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
前言
首先我们得先了解两个概念——上胸围 & 下胸围，具体看示意图：
通过上胸围与下胸围的差值，我们就可以确定罩杯的大小了，具体的对应关系可参考下图：
有了下胸围 & 罩杯就能确定文胸对应的尺码了～
当然这又有分为英式尺码和国际尺码，具体参考下图：
from pyecharts.charts import *from pyecharts import options as optsfrom pyecharts.commons.utils import JsCodefrom collections import Counterimport reimport pandas as pdimport jiebaimport jieba.posseg as psgfrom stylecloud import gen_stylecloudfrom IPython.display import Image数据处理
原始数据是txt格式，为了方便处理，这边转为Dataframe～
尺码部分通过正则表达式提取出对应的下胸围和罩杯，具体代码如下：
In [2]:
patterns = re.compile(r'(?P<datetime>.*),颜色分类:(?P<color>.*?);尺码:(?P<size>.*?),(?P<comment>.*)')with open('/home/kesci/input/cup6439/cup_all.txt', 'r') as f: data = f.readlines()obj_list = []for item in data: obj = patterns.search(item) obj_list.append(obj.groupdict()) data = pd.DataFrame(obj_list)data = pd.concat([data, data['size'].str.extract('(?P<circumference>[7-9]{1}[0|5]{1}).*(?P<cup>[a-zA-Z])', expand=True)], axis=1)data.head()Out[2]:
| color | comment | datetime | size | circumference | cup | |
|---|---|---|---|---|---|---|
| 0 | 肤色薄款 | 不错给婆婆买的，准备再买两件 | 2017-04-20 13:06:04 | 38/85C | 85 | C |
| 1 | H007宝蓝色加粉色 | 和想象的一样好！价格实惠！拢胸效果很好穿着舒服，就是我要的是宝蓝加肤色！给发了一件粉色，也不... | 2017-04-23 21:44:20 | 34/75B | 75 | B |
| 2 | 超薄杯纯洁白 | 真的不错 | 2017-05-18 10:36:31 | 80C | 80 | C |
| 3 | 浅紫 | 一次买了两件，内衣质量不错，无钢圈设计穿上很舒服也很有型，值得购买。 | 2017-04-19 20:44:51 | 36B=80B | 80 | B |
| 4 | 卡其色 | 因为手机号填错了结果直接被退件了_(：_」∠)_但是卖家还是超好心地给我重新送了回来qwq | 2017-05-07 09:16:47 | 75A | 75 | A |
商品类别
我们通过jieba分词来看看商品分类中最常出现的是哪些关键词～
颜色：肤色 > 黑色 > 粉色 > 白色；
薄款 > 厚款；
钢圈似乎是个比较重要的卖点；

单看罩杯的话：B > A > C
细分到具体尺码：75B > 80B > 75A > 70A

罩杯分布
我们通过不同的胸围来看看罩杯的比例：
下胸围=70：A > B > C
下胸围=75：B > A > C
下胸围=80：B > A > C
下胸围=85：B > C > A
下胸围=90：C > B > A
下胸围=95：C > B > D

评论词云
最后我们来看看评论中经常说到的是什么词语吧～
In [8]:
w_all = []for item in data.comment: w_l = jieba.lcut(item) w_all.extend(w_l)c = Counter(w_all)In [10]:
