while using subprocess in python the output is coming with new line

Question

When i execute the below code the output is coming with new line.

import os import sys import subprocess password_string='abc_123' cmd=["java", "-cp", "ABC.jar","com.sc.tsaas.EncryptionDecryptionAES",password_string] i=subprocess.Popen(cmd,stdout=subprocess.PIPE).communicate()[0] print (i)

Output : aSjD9H2NfmX02KpFg==

New line is coming in output and need your help to solve this.

There's always a newline there; the only reason you don't see it in shell is that shells strip trailing newlines from command substitution output. — Charles Duffy

To strip the newline, do i=subprocess.Popen(cmd,stdout=subprocess.PIPE).communicate()[0].rstrip("\n")
