问题001-1：请对输入三个整数a,b,c,判断能否以它们为三个边长构成三角形。若能，输出YES和面积，否则输出NO

a = float(input())

b = float(input())

c = float(input())

if a > 0 and b > 0 and c > 0: #判断边长是否为正

if (a + b > c) and (a + c > b) and (b + c > a): #判断是否可以为三角形

p = (a + b + c)/2.0

S = (p*(p – a)*(p – b)*(p – c))**0.5 #面积，海伦公式

print(“YES, 边长为: a = {},b = {},c = {}, 面积为:{}”.format(a,b,c,S))

else:

print(“NO”)

else:

print(“NO”)

问题001-2：可逆素数是将某素数的各位数字顺序颠倒后仍为素数的数，请编程并输出200以内的可逆素数

注意：1不是素数也不是合数

def GetReNums(n):

if ((n//100 ==0) & (n//10 ==0)):

num1 = n

num2 = n

else:

if ((n//100 ==0) & (n//10 !=0)):

num1 = n

num2 = n%10 * 10 + n//10

else:

num1 = n

num2 = n%100%10 * 100 +n//10%10*10 +n//100

return num1,num2

for n in range(2,200,1):

num1,num2 = GetReNums(n)

devn1 = 0

devn2 = 0

for i in range(2,num1,1):

if (num1%i ==0):

devn1 = devn1+1

for i in range(2,num2,1):

if (num2%i ==0):

devn2 = devn2+1

if ((devn1==0)&(devn2==0)):

print(n)
