### Help ##


subprocess.sys.maxsize?
Type:       int
String Form:9223372036854775807
Docstring:
int(x=0) -> int or long
int(x, base=10) -> int or long

Convert a number or string to an integer, or return 0 if no arguments
are given.  If x is floating point, the conversion truncates towards zero.
If x is outside the integer range, the function returns a long instead.

If x is not a number or if base is given, then x must be a string or
Unicode object representing an integer literal in the given base.  The
literal can be preceded by '+' or '-' and be surrounded by whitespace.
The base defaults to 10.  Valid bases are 0 and 2-36.  Base 0 means to
interpret the base from the string as an integer literal.
>>> int('0b100', base=0)
4



subprocess.os.stat?
Type:       builtin_function_or_method
String Form:<built-in function stat>
Docstring:
stat(path) -> stat result

Perform a stat system call on the given path.




subprocess.os.uname?
Type:       builtin_function_or_method
String Form:<built-in function uname>
Docstring:
uname() -> (sysname, nodename, release, version, machine)

Return a tuple identifying the current operating system.
