death_age = 80

name = input(「your name」)

age = input(「your age:」) #input

注:接受的所有資料都是字串,即便你輸入的是數字,但依然會被當成字串來處理

print(type (age))

#int integer = 整數 把字串轉成int,用int(被轉的資料)

#str string =字串 把資料轉成字串用str(被轉的資料)

print(「your name:」,name)

#print("you can still live for ",death_age - int(age),「years …」)

print("you can still live for " + str(deach_age - int(age)) +「years …」)

if語句實現猜年齡

age_of_princal =

56guess_age =

int(

input

(">>:"))

if guess_age == age_of_princal:

print

("yes,you got it.."

)else

:print

("no,it's wrong"

)

表示式if …else語句

縮排 indentationerror:expected an indented block

indentationerror:unindent does not match

any outer indentation level syntaxerror:invalid

syntax 語法錯誤

age_of_princal =

56guess_age =

int(

input

(">>:"))

if guess_age == age_of_princal:

print

("yes,you got it.."

)print

("yes,you got it.."

多分支if語句

1.if判斷語句

age_of_princal =

56guess_age =

int(

input

(">>:"))

if guess_age == age_of_princal:

print

("yes,you got it.."

)elif guess_age > age_of_princal:

print

("shoud try samller.."

)else

:print

("try bigger ... "

if猜成績語句

score =

int(

input

("score:"))

if score >90:

print

("a"

)elif score >80:

print

("b"

)elif score >70:

print

("c"

)elif score >50:

print

("d"

python(分支語句if)(輸入輸出)的練習

1.輸入年 月,輸出本月有多少天。合理選擇分支語句完成設計任務。輸入樣例1 2004 2 輸出結果1 本月29天 輸入樣例2 2010 4 輸出結果2 本月30天 year int input 請輸入年份 month int input 請輸入月份 if year 4 0 and year 100 ...

多分支語句與格式化輸出

多分支語句 語法 if 判斷條件1 語句塊1 elif 判斷條件2 語句塊2 elif 判斷條件3 語句塊3 else 語句塊n 執行過程 首先執行判斷條件1,若條件1成立則執行語句塊1,語句塊1執行完畢則跳出 分支語句.若條件1不成立,則執行判斷條件2,若條件2成立,則執行語句塊2.若條件2不成立...
