Oracle列定义中没有def collatz(number):
if number % 2 == 0:
return number // 2
else:
return number*3 + 1
number = 0
while number == 0:
try:
number = int(input('Please enter a number: '))
if number == 0:
print('Number must be an integer not equal to zero.')
else:
while True:
number = collatz(number)
print(number)
if abs(number) == 1 or number == -5 or number == -17:
break #Collatz seq ends/enters recurring loop when number hits -17, -5, -1 or 1
except ValueError:
print('Number must be an integer.')
子句。甲骨文抱怨，因为它期望在ON UPDATE之后有一个右括号。
