print "2 + 2 is", 2+2 print "3 * 4 is", 3 * 4 print 100 - 1, " = 100 - 1" print "(33 + 2) / 5 + 11.5 = ",(33 + 2) / 5 + 11.5
And here is the output when the program is run:
2 + 2 is 4 3 * 4 is 12 99 = 100 - 1 (33 + 2) / 5 + 11.5 = 18.5
As you can see Python can turn your thousand dollar computer into a 5 dollar calculator.
Python has six basic operations:
Notice that division follows the rule, if there are no decimals to start with, there will be no decimals to end with. The following program shows this:
print "14 / 3 = ",14 / 3 print "14 % 3 = ",14 % 3 print print "14.0 / 3.0 =",14.0 / 3.0 print "14.0 % 3.0 =",14 % 3.0 print print "14.0 / 3 =",14.0 / 3 print "14.0 % 3 =",14.0 % 3 print print "14 / 3.0 =",14 / 3.0 print "14 % 3.0 =",14 % 3.0 print
14 / 3 = 4 14 % 3 = 2 14.0 / 3.0 = 4.66666666667 14.0 % 3.0 = 2.0 14.0 / 3 = 4.66666666667 14.0 % 3 = 2.0 14 / 3.0 = 4.66666666667 14 % 3.0 = 2.0
The order of operations is the same as in math class:
()
**
*
, division \
, and remainder %
+
and subtraction -
