python-3.x - 不可排序的类型：int() < list()

Question

next_number = []

for i in range(len(fib)):

    while next_number < [10]:
        next_number = fib[i] + fib[i + 1]
        fib.append(next_number)

print(next_number)

Traceback (most recent call last):
File "<pyshell#11>", line 1, in <module>
euler_fibbonacci([0, 1])
File "C:\Python33\euler_fibbonacci.py", line 17, in euler_fibbonacci
while next_number < limit:
TypeError: unorderable types: int() < list()

为什么他给我这个错误，因为 next_number 是列表，而 [10] 也是一个列表。

Answer 1

第一次通过你的while循环你这样做：

next_number = fib[i] + fib[i + 1]

fib[i] + fib[i + 1]是一个int。下一次通过检查是否int小于 [10]，这会抛出TypeError.
