The L means its a `long` literal, i.e. an integer value that can be
arbitrary big. Well its limited by memory of course.
And it doesn't "fubar" math, the L just shows up in the string
representation but you don't calculate with strings but numbers.

Just go ahead and do it:
In [185]: stat = os.statvfs('/')
In [186]: stat.f_bsize
Out[186]: 4096
In [187]: stat.f_blocks
Out[187]: 2622526L
In [188]: stat.f_bsize * stat.f_blocks
Out[188]: 10741866496L
