 3 print(msg)      # I am yuan , My hobby is play
 4 #打印浮点数
 5 tpl = "percent %.2f" % 99.976234444444444444
 6 print(tpl)      # percent 99.98
 7 #打印百分比

字符串格式化之——format

 1 # **字典
 2 tpl = "i am {name}, age {age}, really {name}".format(name="seven", age=18)
 3 print(tpl)      # i am seven, age 18, really seven
 4 tpl = "i am {name}, age {age}, really {name}".format(**{"name": "seven", "age": 18})
 5 print(tpl)      # i am seven, age 18, really seven
 6 # *列表
 7 tpl = "i am {:s}, age {:d}".format(*["seven", 18])
 8 print(tpl)      # i am seven, age 18
 9 tpl = "i am {:s}, age {:d}".format("seven", 18) #["seven", 18]
10 print(tpl)      # i am seven, age 18
11 
12 tpl = "numbers: {:b},{:o},{:d},{:x},{:X}, {:%},{}".format(15, 15, 15, 15, 15, 15.87623, 2)
13 print(tpl)  # numbers: 1111,17,15,f,F, 1587.623000%,2
