Remove n characters from a start of a string

Question

I want to remove the first characters from a string. Is there a function that works like this?

>>> a = \"BarackObama\"
>>> print myfunction(4,a         


        

Answer 1

Use slicing.

>>> a = "BarackObama"
>>> a[4:]
'ckObama'
>>> b = "The world is mine"
>>> b[6:10]
'rld '
>>> b[:9]
'The world'
>>> b[:3]
'The'
>>>b[:-3]
'The world is m'
