Answer:

Handwritten methods:

#just a helper METHOD to not have to write this more than once

DEF value_checker(n):

if isinstance(n, str):

n=INT(n) #raises an ValueError

except ValueError:

return False

if not isinstance(n, int): return False

return n>=0

#recursive method

#the helping bool variable avoids running the valuecheck serval times

def fac_rec(n, valueChecked=False):

if valueChecked or value_checker(n):

return 1 if n==0 else n*fac_rec(n-1, True)

return "NaN"

#iterativ method

def fac_iter(n):

if value_checker(n):

r=1

for i in range(2, n+1):

r*=i

return r

return "NaN"

from functools IMPORT reduce

fac_lambda=lambda n:"NaN" if not value_checker(n) else reduce(lambda a, b:a*b, range(1, n+1))

Hope it helped u..✌️
