習題14 - 提示和傳遞

用Notepad++打下列的程式碼,
另存為ex14.py.

from sys import argv

script, user_name = argv
prompt = '> '

print (f"Hi {user_name}, I'm the {script} script.")
print ("I'd like to ask you a few questions.")
print (f"Do you like me {user_name}?")
likes = input (prompt)

print (f"Where do you live {user_name}?")
lives = input (prompt)

print ("What kind of computer do you have?")
computer = input (prompt)

print (f"""
Alright, so you said {likes} about liking me.
You live in {lives}, Not sure where that is.
And you have a {computer} computer. Nice
""")

然後用Windows的cmd, 執行python打開它. (並在後面加了1個參數: Peter)

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

C:\Users\Peter\Desktop\Python\LP3THW>python .\ex14.py Peter
Hi Peter, I'm the .\ex14.py script.
I'd like to ask you a few questions.
Do you like me Peter?
> Yes
Where do you live Peter?
> China
What kind of computer do you have?
> ThinkPad T430s

Alright, so you said Yes about liking me.
You live in China, Not sure where that is.
And you have a ThinkPad T430s computer. Nice

完成

我們來修改一下程式碼.
Line 4, 使用格式化"f"讓提示字符更多樣化.
Line 9, 讓這likes輸入必須是字浮串, 若輸入數字會出錯.
Line 10, 印出出這likes的形態, 這招很重要!!
Line 11, 印出這likes 的string格式的值, 這招很重要!!

from sys import argv

script, user_name = argv
prompt = f'{script}@{user_name}> '

print (f"Hi {user_name}, I'm the {script} script.")
print ("I'd like to ask you a few questions.")
print (f"Do you like me {user_name}?")
likes = int(input (prompt))
print (">>>> type >>>>", type (likes))
print (">>>> repr >>>>", type (repr (likes)))


print (f"Where do you live {user_name}?")
lives = input (prompt)

print ("What kind of computer do you have?")
computer = input (prompt)

print (f"""
Alright, so you said {likes} about liking me.
You live in {lives}, Not sure where that is.
And you have a {computer} computer. Nice
""")

結果,

C:\Users\Peter\Desktop\Python\LP3THW>python ex14.py Peter
Hi Peter, I'm the ex14.py script.
I'd like to ask you a few questions.
Do you like me Peter?
ex14.py@Peter> 111
>>>> type >>>> <class 'int'>
>>>> repr >>>> <class 'str'>
Where do you live Peter?
ex14.py@Peter> AAA
What kind of computer do you have?
ex14.py@Peter> BB1B

Alright, so you said 111 about liking me.
You live in AAA, Not sure where that is.
And you have a BB1B computer. Nice
