If you want to assign csv export to a variable in python

Use io.StringIO

from io import StringIO                                                                                     
import csv                                                                                                  
                                                                                                            
f = StringIO()                                                                                              
writer = csv.writer(f, quotechar='"', quoting=csv.QUOTE_ALL, lineterminator="\n")                           
writer.writerow(['foo,', 'bar'])                                                                             
writer.writerow(['"Ai', 'Ueo\''])                                                                      
result = f.getvalue()                                                                                       
print(type(result))                                                                                         
print(result)

csvfile parameter specifications

According to Document, the following parameters can be specified. csv.writer(csvfile[, dialect='excel'][, fmtparam]) It seems that the csvfile object can be any object that has a write method. Therefore, sys.stdout etc. can also be specified.

I did a little research from the request that I want to be able to copy and paste on the WEB instead of exporting as CSV and saving it in a file. I found how to use StringIO in the csv module test (Python-3.5.2 / Lib / test / test_csv.py).
