下表列出了所有Python语言支持的算术运算符。假设变量a持有10和变量b持有20，则： [img]http://files.jb51.net/file_images/article/201505/2015513115413853.jpg?2015413115427[/img]  例子: 试试下面的例子就明白了所有的Python编程语言提供了算术运算符： #!/usr/bin/python a = 21 b = 10 c = 0 c = a + b print "Line 1 - Value of c is ", c c = a - b print "Line 2 - Value of c is ", c c = a * b print "Line 3 - Value of c is ", c c = a / b print "Line 4 - Value of c is ", c c = a % b print "Line 5 - Value of c is ", c a = 2 b = 3 c = a**b print "Line 6 - Value of c is ", c a = 10 b = 5 c = a//b print "Line 7 - Value of c is ", c 当执行上面的程序，它会产生以下结果： Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1 Line 6 - Value of c is 8 Line 7 - Value of c is 2
