python，拜托纠正错误！
程序运行不了，应该有很多错误的地方，拜托指正！谢谢。题目：
找出800-1200之间所有符合以下条件的数：该数的各位数字的阶乘和为素数。按如下格式打印出所有符合条件的数：
807:8!+0!+7!=45361
817:8!+1!+7!=45361
870:8!+7!+0!=45361
871:8!+7!+1!=45361
1002:1!+0!+0!+2!=5
1012:1!+0!+1!+2!=5
1020:1!+0!+2!+0!=5
…………
程序中包含两个函数，分别用于实现判断素数和计算阶乘。
for i in range(800,1201):
st=str(i)
for j in st:
jie=1
sum=0
m=1
all_data=[]
num=0
while int(j) >= m:
jie=jie*m
sum=sum+jie
m=m+1
print(sum)
num+=1
all_data.append(sum)
for sum in all_data:
k=2
if sum%k==0:
break
else:
k+=1
print(i":"i"!+"i"!+"i"!="sum) 不用造函数的方法这样能搞出来吗？

elif n == 2 or n == 3 or n == 5 or n == 7:

return r
def jc(n):

for i in range(n):

return r
for i in range(800 , 1201):
j , d = i , []
while j:
d . insert(0 , j % 10)
j //= 10
e = []
for k in range(len(d)):
e . append(jc(d))
s = sum(e)
if prime(s):
t = "%d:%d!" % (i , d)
for k in range(1 , len(d)):
t += '+%d!' % d
t += '=%d' % s
print(t)
运行时况
