習題12 - 提示別人

用Notepad++打下列的程式碼,
另存為ex12.py.

age = input ("How old are you? ")
height = input ("How tall are you? ")
weight = input ("How much do you weigh? ")

print (f"So, you're {age} old, {height} tall and {weight} heavy.")

然後用Windows的cmd, 執行python打開它.

C:\Windows\System32>cd C:\Users\Peter\Desktop\Python\LP3THW

C:\Users\Peter\Desktop\Python\LP3THW>python .\ex12.py
How old are you? 111
How tall are you? 222
How much do you weigh? 333
So, you're 111 old, 222 tall and 333 heavy.

完成

這次練習主要是學習對字符串做更多複雜的格式化.
我們來修改一下程式碼.
Line 1 - 2, int是轉換成整數,並打印出該數據類型(應為整數).
Line 3 - 4, float是轉換成浮點數,並打印出該數據類型(應為浮點數).
Line 5 - 6, str是轉換成字串,並打印出該數據類型(應為字串).
Line 8, 用另外一個方法表示出相同的格式化結果.

age = int (input ("How old are you? "))
print (type (age))
height = float (input ("How tall are you? "))
print (type (height))
weight = str (input ("How much do you weigh? "))
print (type (weight))

print ("So, you're {} old, {} tall and {} heavy.".format (age, height, weight))

結果,

C:\Users\Peter\Desktop\Python\LP3THW>python .\ex12.py
How old are you? 111
<class 'int'>
How tall are you? 222
<class 'float'>
How much do you weigh? 333
<class 'str'>
So, you're 111 old, 222.0 tall and 333 heavy.
