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

‘贰’ python如何输入任意字符重复运行一次代码

用while循环
value = input("请随意输入：")
count = 0
while True:
if value == "e" or value == "E":
break
count += 1
print("test %d" % count)
value = input("按任意键继续，按E结束：w")

‘叁’ 怎样用python在代码运行完重复运行

前面加一个while函数
可以用while
True
也可以设置一个问题例如输入’开始’进行，输入’退出’结束
希望对你有帮助
