問題001-1：請對輸入三個整數a,b,c,判斷能否以它們為三個邊長構成三角形。若能，輸出YES和面積，否則輸出NO

a = float(input())

b = float(input())

c = float(input())

if a > 0 and b > 0 and c > 0: #判斷邊長是否為正

if (a + b > c) and (a + c > b) and (b + c > a): #判斷是否可以為三角形

p = (a + b + c)/2.0

S = (p*(p – a)*(p – b)*(p – c))**0.5 #面積，海倫公式

print(“YES, 邊長為: a = {},b = {},c = {}, 面積為:{}”.format(a,b,c,S))

else:

print(“NO”)

else:

print(“NO”)

問題001-2：可逆素數是將某素數的各位數字順序顛倒后仍為素數的數，請編程并輸出200以內的可逆素數

注意：1不是素數也不是合數

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)
