Learn Python the Hard Way 14 Prompting and Passing

將 argv 和 input 結合

from here

這次要來把 argv 跟 input 結合在一起，可以拿來問使用者比較具體的問題，這次我們也會在 input 加個小提示 “ > “，來提醒使用者。

from sys import argv
script, user_name = argv
prompt = '> '
print(f"Hi {user_name}, I'm the {script} script.")
print("I's 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.
""")

接著在 Terminal 輸入：

python ex14.py Chenyu

output:

Hi Chenyu, I'm the ex14.py script.
I'm like to ask you a few questions.
Do you like me Chenyu?
> Yes
Where do you live Chenyu?
> Taipei
What kind of computer do you have?
> Mac
Alright, so you said Yes about liking me.
You live in Taipei. Not sure where that is.
And you have a Mac computer. Nice.

我們也可以把變數 prompt 改一下，程式看起來兇一點！

from sys import argv
script, user_name = argv
prompt = 'Huh? '
print(f"Hi {user_name}, I'm the {script} script.")
print("I's 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.
""")

output:

Hi Chenyu, I'm the ex14.py script.
I'm like to ask you a few questions.
Do you like me Chenyu?
Huh? No...
Where do you live Chenyu?
Huh? Secret
What kind of computer do you have?
Huh? I don't know...
Alright, so you said No... about liking me.
You live in Secret. Not sure where that is.
And you have a I don't know... computer. Nice.
