EOF while reading the input error while using python

#1

Here is the code

#2

error is not EOF error
it is type error

at line 8
ans = int(fac_2n/fac_nfac_n(n+1))
here n is string not int so you can’t write like that

correct way to do this is

n = int(input())
fac_2n = 1
fac_n = 1
for i in range(1,2*n+1):
	fac_2n = fac_2n*i


for i in range(1,n+1):
	fac_n = fac_n*i;

ans = fac_2n/(fac_n*fac_n*(n+1))
print(ans)

convert first n to int and then proceed
