Python type cast long to int code _python

After the python2.4 version, if the value of the int does not overflow but is internally converted to long, there is no code on the net that is cast to int from the long type, where the int value range is consistent with Java, that is, four bytes.
Wrote a function of their own, barely can be used for everyone's reference.

Copy Code code as follows:

Import Sys
def longtoint (value):
Assert Isinstance (value, (int, long)
return int (value & sys.maxint)

After testing, the results are consistent on 32-bit and 64-bit operations.
