<class 'pandas.core.frame.DataFrame'>
Index: 450 entries, Java to java高级工程师
Data columns (total 12 columns):
1 450 non-null object
2 450 non-null object
3 450 non-null object
4 450 non-null object
5 450 non-null object
6 450 non-null object

8 450 non-null object
9 399 non-null object
10 450 non-null object
11 435 non-null object
12 415 non-null object
dtypes: object(12)
memory usage: 55.7+ KB
从打印的数据来看提取出来的数据列索引为9，11，12都有缺失
'''
因为要选第11列内容作为词云的数据源，可以对11列内容做缺失补偿，具体代码如下
from sklearn.impute import SimpleImputer
#众数填补缺失值
mode=SimpleImputer(strategy='most_frequent')
mode=mode.fit_transform(treatment)
mode[:20]
data.loc[:,'11']=mode
data.info()
'''
9 399 non-null object
10 450 non-null object
11 450 non-null object
12 415 non-null object
从index=11的查询出来的个数可以判定此列已经被众数填补缺失值
'''
下面收集数据写入到切片
temp=[]
for item in data['11']:
items=item.split("|")
for each in items:
temp.append(each)
