将DataFrame中的内容转换为txt文件

Question

I just ask somethings~ I wanna make Word Cloud. so I extracted my data from mysql using pymysql. My script like below

import sys
import pymysql
import pandas as pd
conn = pymysql.connect(host='localhost', user='root', password='secret',
                   db='first_day', charset='utf8')
curs = conn.cursor(pymysql.cursors.DictCursor)
sql = "select * from first_day_datas"
curs.execute(sql)
rows = curs.fetchall()
df = pd.DataFrame(rows)
print(df.head())
df = df[pd.notnull(df['longitude'])]
print(df.head())

and my data status like below picture

I alreay got rid of the rows in which doesn't contain longtitude value. Here is my question. How can I convert 'blogtext' column to .txt file?? I will make wordcloud using wordcloud libarary.

Answer 1

I think you need Series.to_csv , also it seem you need omit first index column:

df['blogtext'].to_csv('myfile.txt',index=False)

Sample:

df = pd.DataFrame({'blogtext':['a','s','d'],
                   'address':['o','i','r']})
print (df)
  address blogtext
0       o        a
1       i        s
2       r        d

print (df['blogtext'].to_csv(index=False))
a
s
d

---

print (df['blogtext'].to_csv())
0,a
1,s
2,d

Answer 2

Assume you want line by line format for each row

with open('/tmp/data.txt', 'w') as f:
    for row in map(str, df.head()['blogtext']):
        f.write(row + "\n")
