讓程式不斷地執行

獲取使用者輸入並學會控制程式的執行時間，互動式程式

input()function

name =

input
('enter you name please: '
)print
('good evening, '
+ name +
'!')

hint =

'\npjs kissed toes of a member when he was drunk.'
hint +=
'\nwho is that member? '
answer =
input
(hint)
if answer ==
'ljn'
:print
('\nyes, he kissed '
+ answer 
+"'s toes. haha"
)else
:print
("\nsorry, the one pjs kisssed"
+'is not '
+ answer)

input()獲得的輸入被自動解讀為字串，無法作為數字使用

numberofhuaren =

answer =
input
('\nnct is limitless, so it expands'
+' every year. \nwhen did you become a haufen? '
)answer =
int(answer)
for year, number in numberofhuaren.items():
if year == answer:
print
('in '
+str
(answer)
+', the number of '
+'huaren is '
+str
(number)
)

%：將兩個數相除並返回餘數

(input)if
input%2
==0:print
('the number '
+str
(input)+

)else
:print
('the number '
+str
(input)+
' is odd'
)

current_number =

1while current_number <=5:
print
(current_number)
, current_number +=
1# current_number = current_number + 1

prompt =

'\ntell me something, and i will repeat it back to you: '
prompt +=
"\nenter 'quit' to end the program. "
message =
""while message !=
'quit'
: message =
input
(prompt)
if message !=
'quit'
:#列印訊息前對訊息進行檢查
print
(message)

使用者輸入和while迴圈

函式input 讓程式暫停執行，等待使用者輸入一些文字。獲取使用者輸入後，python將其儲存在乙個變數中，以方便你使用。函式input 接受乙個引數 即要向使用者顯示的提示 或說明，讓使用者知道該如何做。在這個示例中，python執行第1行 時，使用者將看到提示tell me something,...
