Formatting a dataframe in Pandas-CodePudding

I got a dataframe looking like this:

       A    B    C 
0      1    2    3
1      2    2    1

I want to send the values from the dataframe into a HTTP POST where the format looks like this:

"1,2,3",
"2,2,1",

How is it possible to format the output from the dataframe to be able to achieve desired output?

CodePudding user response：

You can convert values to strings if need join them:

L = df.astype(str).agg(','.join, 1).tolist()
print (L)
['1,2,3', '2,2,1']

For json output convert list:

import json

j = json.dumps(L)
print (j)
["1,2,3", "2,2,1"]
