[Tutor] How to remove a newline character

[A]

Hi,
Can you please let me know  if it is possible to replace 
new line characters( '\n') in a list in one step?

I have list like

MyList=['272580\n', '23232432\n']

and I would like to have 
,MyList=['272580', '23232432']

so I tried
re.sub('\n','',MyList)
but I received 
TypeError: expected string or buffer

Your help would be appreciated
Thanks.
Ladislav

I look forward to hearing from you soon.

Best Regards,
Ladislav Blazek( Mr.)
