I want to write an algorithme which calculate the factorial of number then search how many a charactere is rewrited

Question

Why This dont't work,but separatelly it work
#factorial
factorial=abs(int(input('wright a number')))
n=factorial-1
r=factorial//10
i=0
while n!=0:
factorial=factorial*n;
n=n-1
print('the factorial of the number is',factorial)

char=input("what do you search:")
def search(factorial,char):
i=0
for c in factorial:
if c==char:
i+=1
return(i)

print(search(factorial,char))

Answer 1

~ swim ~ thank you it work
But why i can't iterate an integer ?

Answer 2

Thank you ~ swim ~ you are so helpful
