A value can be assigned to sevaral variables simultaneously. Complex numbers are also supported. Imaginary numbers are written with a suffix j or J. In a complex number z, z.real and z.imag returns real and imaginary parts respectively. In interactive mode the last printed character is assigned to a variable'_'.

>>> x = y = z = 0

>>> -1j * 1j
(1+0j)

>>> a=678

>>> a*23
15594

>>> print _
15594

>>> _/22
