How can i remove the first character from a StringIO object?

Question

I couldn't figure it out with the Python documentation, so maybe i can ask it here:

import StringIO
line = StringIO.StringIO()
line.write('Hello World')

Is there any method i can use, that will do what line[1:] would do on a string, so line.getvalue() will return ello World?

Thanks.

I can't figure out how to do it with line.getvalue, but you can use StringIO objects like normal file objects. Just seek to byte 1 and read as you normally would.

>>> import StringIO
>>> line = StringIO.StringIO()
>>> line.write("Hello World")
>>> line.seek(0)
>>> print line.getvalue()
Hello World
>>> line.seek(1)
>>> print line.getvalue()
Hello World
>>> line.seek(1)
>>> print next(line)
ello World
>>> line.seek(1)
>>> print line.read()
ello World

The StringIO getvalue() function return the content as string, so this could be work:

content = line.getvalue()
print content[1:]
