How can I covert in Python a variable of a long type to variable of
Integer type?
Thank you for reply

You can do "int(variable)" , but it can't be always done (for example,
when variable > MAX_INT):
[color=blue][color=green][color=darkred]
>>> a=10L
>>> a[/color][/color][/color]
10L[color=blue][color=green][color=darkred]
>>> int(a)[/color][/color][/color]
10[color=blue][color=green][color=darkred]
>>> a=1000000000000 000000000000000 000000000000000 000000000000000 000000L
>>> a[/color][/color][/color]
100000000000000 000000000000000 000000000000000 000000000000000 0000L[color=blue][color=green][color=darkred]
>>> int(a)[/color][/color][/color]
100000000000000 000000000000000 000000000000000 000000000000000 0000L

A more concrete example:[color=blue][color=green][color=darkred]
>>> int(2**31)[/color][/color][/color]
2147483648L[color=blue][color=green][color=darkred]
>>> int(2**31-1)[/color][/color][/color]
2147483647[color=blue][color=green][color=darkred]
>>> int(-2**31)[/color][/color][/color]
-2147483648[color=blue][color=green][color=darkred]
>>> int(-2**31-1)[/color][/color][/color]
-2147483649L

The above value is a float, not a long ...
[color=blue][color=green][color=darkred]
>>>>int(10/3.0)[/color][/color]

>[color=green][color=darkred]
>>> int(1l)[/color][/color][/color]
1[color=blue][color=green][color=darkred]
>>> 100000000000000 000000[/color][/color][/color]
100000000000000 000000L[color=blue][color=green][color=darkred]
>>> 100000000000000 000000/100000000000000 0000[/color][/color][/color]
100L[color=blue][color=green][color=darkred]
>>> int(10000000000 0000000000/100000000000000 0000)[/color][/color][/color]
100[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]
