Python求階乘

# coding:utf-8
# 使用遞迴求階乘

print('Recursive factorial !')
enterNumber = int(input('Please enter a number:\n'))
# 求階乘的方法
def recursiveMethod(number):
	'''
	This method is used to find the factorial !!!
	return:recursiveMethod
	'''
	if number == 0:
		return 0
	elif number == 1 :
 
 
		return 1
	else:
		return number*recursiveMethod(number-1)
# 呼叫
print('{}的階乘是:{}'.format(enterNumber,recursiveMethod(enterNumber)))
