Here is a Python Program for Simple Numeric Calculation
#!/usr/bin/python
# Some calculations. Note the lack of semicolons. Statements end at the end
# of the line. Also, variables need not start with a special symbol as in
# perl and some other Unix-bred languages.
fred = 18
barney = FRED = 44; # Case sensistive.
bill = (fred + barney * FRED - 10)
alice = 10 + bill / 100 # Integer division truncates
frank = 10 + float(bill) / 100
print "fred = ", fred
print "bill = ", bill
print "alice = ", alice
print "frank = ", frank
print
# Each variable on the left is assigned the corresponding value on the right.
fred, alice, frank = 2*alice, fred - 1, bill + frank
print "fred = ", fred
print "alice = ", alice
print "frank = ", frank
print
# Exchange w/o a temp.
fred, alice = alice, fred
print "fred = ", fred
print "alice = ", alice
print
# Python allows lines to be continued by putting a backslash at the end of
# the first part.
fred = bill + alice + frank - \
barney
print "fred =", fred
print
# The compiler will also combine lines when the line break in contained
# in a grouping pair, such as parens.
joe = 3 * (fred +
bill - alice)
print "joe =", fred
