Code for forcibly converting long to int of python type

After python2.4, if the int value is not exceeded, but is converted to long internally, no code is found to forcibly convert from long to int on the Internet, the int value range is the same as that in java, that is, four bytes are used.
I wrote a function, which is barely usable for your reference.

Copy codeThe Code is as follows: import sys
Def LongToInt (value ):
Assert isinstance (value, (int, long ))
Return int (value & sys. maxint)

After testing, the computation results on 32-bit and 64-bit are the same.
