python - convert csv to a string variable -

i beginner in python. need following

i have comma separated csv file, eg

a,b,c d,e,f g,h,i 

i need convert string variable eg s='a,b,c\n,d,e,f\n,g,h,i\n'

i tried something, going wrong somewhere.

import os import csv filename=r"c:\users\das\desktop\a.csv" z=open(filename, 'r') reader=csv.reader(filename.split('\n'),delimiter=',') def csv2str():     row  in reader:         v=','.join(row)  a=csv2str() 

you don't need csv module that. call read method of file object read in lines 1 string:

with open(filename) f:     s = f.read() + '\n' # add trailing new line character  print(repr(s)) # 'a,b,c\nd,e,f\ng,h,i\n' 

i'm printing repr of string because print of string i.e. print(a) not show newline character \n, show string in different lines.
