# truthtable.py
# D. Thiebaut
# how a simple python program can generate the
# truth table of a boolean function
#
# here f is a function of 3 variables
# _
# f = a.b + c
# _ _ _
# g = a + b + c
def f( a, b, c ):
return ( a and not b ) or c
def g( a, b, c ):
return not a or not b or not c
def main():
print " a b c | f g "
print "-----------+--------"
for a in [ 0, 1 ]:
for b in [ 0, 1 ]:
for c in [ 0, 1 ]:
print "%3d%3d%3d |%3d%3d" % \
( a, b, c, f( a, b, c ), g( a, b, c ) )
main()
The output is show below:
a b c | f g
-----------+--------
0 0 0 | 0 1
0 0 1 | 1 1
0 1 0 | 0 1
0 1 1 | 1 1
1 0 0 | 1 1
1 0 1 | 1 1
1 1 0 | 0 1
1 1 1 | 1 0
