What you shared is not valid python code. Here is an example of code that will accomplish what you are asking:
# define function:
def CalculateMortgage(p, i, n):
# calculate numerator:
numerator = p * (i *(1+i) ** n)
# calculate denominator:
denominator = ((1+i) ** n - 1)
# calculate mortgage:
mortgage = numerator/denominator
# return result:
return mortgage
# set variables:
p = 1
i = 1
n = 1
# call function:
mortgage = CalculateMortgage(p, i, n)
# print result:
print('Your mortgage is: ' + str(mortgage))
