算术运算符

代码:
a=21;
b=10;
c=0;
c=a+b;
print("a+b的值为: ",c);
c=a-b;
print("a-b的值为: ",c);
c=a*b;
print("a*b的值为: ",c);
c=a/b;
print("a/b的值为: ",c);
#取余
c=a%b;
print("a%b的值为: ",c);
#幂次方
a=2;
b=3;
c=a**b;
print("a的b次幂为: ",c);
#取整
a=10;
b=5;
c=a//b;
print("a除b,取整: ",c);运行结果:
runfile('D:/新建文件夹/WinPython-64bit-3.3.5.9/settings/.spyder2-py3/My Python Code/key.py', wdir='D:/新建文件夹/WinPython-64bit-3.3.5.9/settings/.spyder2-py3/My Python Code')
a+b的值为: 31
a-b的值为: 11
a*b的值为: 210
a/b的值为: 2.1
a+b的值为: 1
a的b次幂为: 8
a除b,取整: 2关系运算符
代码:

if(a>=b):
print("a>=b");
else:
print("a<b");
if(a<=b):
print("a<=b");
else:
print("a>b");代码结果:
