实现简单的词云和柱状图展示及jiebafen分词和计数

词云

results = ['python','java','python','flask','django','flask']
result_dic = {}
for item_str in results:
    if item_str not in result_dic:
        result_dic[item_str] = 1
    else:
        result_dic[item_str] += 1

python里的运行结果

 

import pandas as pd
from pyecharts import WordCloud
results = ['python','java','python','flask','django','flask']
result = pd.Series(results)
# print(result.value_counts())
yuyan = result.value_counts().index
nums = result.value_counts().values
wd = WordCloud(width=1300,height=620)
wd.add("",yuyan,nums,word_size_range=(20,100))
wd.render('yuyancloud.html')

 

柱状图

a = [1,2,3,4,5,6]

zip(a,b)
Out[4]: <zip at 0x196647ce948>

    print(i)

(2, 0.78)

for i  in range(6):
    a_i = a[i]
    b_i = b[i]
    print(a_i,b_i)

Out[7]: [(1, 0.13), (2, 0.78), (3, 0.6), (4, 0.92), (5, 0.66), (6, 0.33)]

import numpy as np

    r = a[i]*b[i]
    if r > max:
        max = r

jieba分词

import jieba
r = jieba.cut('孤舟蓑笠翁,独钓寒江雪')
for i in r:
    print(i)
孤舟
蓑笠
翁
,
独钓
寒江雪    

r=jieba.cut('孤舟蓑笠翁,独钓寒江雪')
result = []
for i in r:
    result.append(i)
result    
Out[39]: ['孤舟', '蓑笠', '翁', ',', '独钓', '寒江雪']

 计数value_counts

import pandas as pd
results = ['python','java','python','flask','django','flask']
result = pd.Series(results)
result.value_counts()
Out[49]: 
python    2
flask     2
django    1
java      1
