Nim: [Bug]strip() not clear white-space escape characters

[muhammad-al-baqir-khalid]

strip() should clear "\n" from string because it's just whitespace escape characters
example:
import strutils
var x = "\n".strip()
echo(x)

in python it's does the job like it's should be

It seems that this is because \n is not listed here https://nim-lang.org/docs/strutils.html#Whitespace

Hmm, I am not able to reproduce this issue on Nim devel (built today).

Evaluating:

import strutils
echo "«" & "\n string \n \n\n".strip() & "»"
echo "«" & "\n".strip() & "»"

gives:

«string»
«»

[muhammad-al-baqir-khalid]

it's keep one line empty
try
import strutils
echo("\n \n").strip()

@muhammad-al-baqir-khalid

The empty line is because of echo "" 😄

@muhammad-al-baqir-khalid See stdout.write (example) if you want to echo without newlines.

@kaushalmodi Thanks 👍 i know it but i just forget echo make new line
