python习题5

1.修改所有变量名字，把ex5.py的my_去掉，试着使用变量将英镑和寸转换成千克和厘米

 1 name = 'Zed A.Shaw'
 2 age = 35 #not a lie
 3 height = 74 #inches
 4 weight = 180 #lbs
 5 eyes = 'Blue'
 6 teeth = 'White'
 7 hair = 'Brown'
 8 
 9 print(f"Let's talk about {name}.")
10 print(f"He's {height*2.54} inches tall.")
11 print(f"He's {weight*0.45} pounds heavy.")
12 print("Actually that's not too heavy.")
13 print(f"He's got {eyes} eyes and {hair} hair.")
14 print(f"He's teeth are usually {teeth} depending on the coffee.")
15 
16 # this line is tricky,try to get it exactly right
17 total = age + height*2.54 + weight*0.45 
18 print(f"If I add {age},{height},and {weight} I get {total}.")

 

一个疑问，为什么我直接在17行下插入一行round(total)，total结果依旧是个很长的浮点数。
