result=1
n=input("Deme un numero \n")
for i in range (1,n):
   result=result*i
print(result)

my question is how do I write the for range in the part of (1, n ) if 'n' is the number that I must reach or stop the for

Just like the comment says you have to change an by n + 1, since the for what it does is to do from 1 to n-1, when i is n, the code inside the loop is not executed anymore.

result=1
n=int(input("Deme un numero \n"))
for i in range (1,(n+1)):
   result=result*i
print(result)
