python中如何实现print函数格式化输出？

print(*objects, sep=' ', end='\n', file=sys.stdout)

print ("His name is %s"%("Aviad"))

strHello = "the length of (%s) is %d" %('Hello World',len('Hello World'))

print strHello

#输出果：the length of (Hello World) is 11

a = 3.1415926

print "%f" %a

输出为：

3.141593

print ("Name:%10s Age:%8d Height:%8.2f"%("Aviad",25,1.83))
