Python, Need Long Value to be Integer

I'm trying to insert a unix timestamp using REST to a webservice. And when I convert the dictionary I get the value: 1392249600000L I need this value to be an integer.

So I tried int(1392249600000L) and I get 1392249600000L, still a long value.

The reason I need this is because the JSON webservice only accepts timestamsp with milliseconds in them, but when I pass the JSON value with the 'L' in it I get an invalid JSON Primative of value 1392249600000L error.

Can someone please help me resolve this? It seems like it should be so easy, but it's driving me crazy!

You should not be using Python representations when you are sending JSON data. Use the json module to represent integers instead:

>>> import json
>>> json.dumps(1392249600000L)
'1392249600000'

In any case, the L is only part of the string representation to make debugging easier, making it clear you have a long, not int value. Don't use Python string representations for network communications, in any case.

For example, if you have a list of Python values, the str() representation of that list will also use repr() representations of the contents of the list, resulting in L postfixes for long integers. But json.dumps() handles such cases properly too, and handle other types correctly too (like Python None to JSON null, Python True to JSON true, etc.):

>>> json.dumps([1392249600000L, True, None])
'[1392249600000, true, null]'
