Python fourth day factorial

have been learning, but did not come to the blog park, write some, write a factorial small code

def f (N):    last =1     for  in range (1,n+1):        last *=i    return  lastnum=int (input ('what thenumber\n' ) Print ('f'+'('+str (num) +') = ', F (num))

Or with a recursive approach.

def fact (n):    if n==1:        return 1    return  n*fact (n-1) num=int (input (' What the number\n ') print (' fact ' + ') ( ' +str (num) + ') = ', fact (num))

The following is a Fibonacci sequence of three ideas:

1:

def Fibo (n):    befor=0    after=1 for    i in range (n-2):        ret=after+befor        befor=after        After=ret    return Retprint (Fibo (7))

2:

def Fibo (n):    if n==1:        return 0    elif n==2:        return 1    return Fibo (n-1) +fibo (n-2) print (Fibo (7))

3:

def Fibo (n):    if n<=2:        return n-1    return Fibo (n-1) +fibo (n-2) print (Fibo (7))
