while(1):

print('Welcome to use calculator of BMI exponent for human:')

w = float(input('Please enter your weight(kg):'))

h = float(input('Please enter your height(m):'))

BMI = w / (h * h)

if BMI < 18.5: print('you are thin !')

if 18.5 <= BMI <=24.9: print('you are normal !')

if BMI >=25: print('you are little fat !')

if 25.0 < BMI <=29.9: print('you are more little fat !')

if 30.0 <= BMI <= 34.9: print('you are fat !')

if 35.0 <= BMI <=39.9: print('you are serious fat !')

if BMI >=40: print('you are extreme fat !')

print('continue?Y/N')

n=''

while(n!='Y' and n!='N'):

n=input()

if(n=='N'):

break

『貳』 python如何輸入任意字元重復運行一次代碼

用while循環
value = input("請隨意輸入：")
count = 0
while True:
if value == "e" or value == "E":
break
count += 1
print("test %d" % count)
value = input("按任意鍵繼續，按E結束：w")

『叄』 怎樣用python在代碼運行完重復運行

前面加一個while函數
可以用while
True
也可以設置一個問題例如輸入』開始』進行，輸入』退出』結束
希望對你有幫助
