[Tutor] Convert a string of numbers to a list

[Kyle Kwaiser]

Turns out I was close but had not combined everything.  I never would 
have picked up on the map() function.  Much more efficient than looping 
through the whole mess and converting to int.

x = ['[335, 180, 201, 241, 199]\r\n']
y = map( int, x[0].strip( '[]\r\n' ).split(  ', '  ) ) #need an index here
print y
[335, 180, 201, 241, 199]

Thanks for your help!
