write a program to find factorial of a number in python code example
Example 1: factorial python for loop
'''factorial n! - n* n-1*n-2..1'''
def fac_iterative_method(n):
fac = 1
for i in range(n):
fac = (fac * (i+1))
print('fac of',i+1,'=',fac)
number = int(input('enter the number'))
fac_iterative_method(number)
Example 2: python calculate factorial
def factorial(n):
fact = 1
for num in range(2, n + 1):
fact = fact * num
return(fact)
Example 3: factorial in python
def fact(n):
return 1 if (n==0 or n==1) else n*fact(n-1)
fact(3)
Example 4: quick way to find the factor of a number python
def factors(x):
listOfFactors = []
for i in range(1, int(x ** 0.5)):
if x % i == 0:
listOfFactors.append(x)
listOfFactors.append(i)
print(i)
