- %d 数值
- %s 字符串
- %f 浮点型
举例说明
c1 = 'lily'
c2 = 18
c3 = 1.123
print("My name is %s"%c1)
print("number is : %d " %c2 )
print("the float is : %f " %c3)
print("the float is : %.3f " %c3)
print("my name is %s , my age is %d"%(c1,c2))
结果输出
My name is lily
number is : 18
the float is : 1.123000
the float is : 1.123
my name is lily , my age is 18
