Posted 2021-03-13 forhowcar

1、打印浮点数%f

tp1="percent %.2f"%99.976234444444444444
print(tp1)

tp1="percent %.3f"%99.976234444444444444
print(tp1)

>>>

percent 99.98
percent 99.976

2、打印字符串%s，

      #字符串可接收数字，可接收浮点数

msg1 = ‘my name is %s, my hobby is %s‘   %(‘fu‘,‘pingpang‘)
msg2 = ‘his name is %s‘   %‘zheng‘
print(msg1)
print(msg2)

>>>

my name is fu, my hobby is pingpang
his name is zheng

3、打印数字型%d

msg1 = ‘my name is %s, my age is %d‘   %(‘fu‘,20)
print(msg1)

>>>my name is fu, my age is 20

4打印百分号%%

tpl=‘ percent %.2f %%‘     % 99.976234444
print(tpl)

>>>percent 99.98 %
