AttributeError：'模块'对象没有属性'accumulate'

Question

导入itertools之后，我在下面的代码上运行itertools.accumulate（），并且出现错误提示-

Traceback (most recent call last):
  File "Equal_Stacks.py", line 36, in <module>
    result = equalStacks(h1 , h2 , h3)
  File "Equal_Stacks.py", line 8, in equalStacks
    h11 = itertools.accumulate(h1)
AttributeError: 'module' object has no attribute 'accumulate'

但是当我在解释器中运行itertools.accumulate（）函数时，它就可以正常工作。

import sys
import itertools

def equalStacks(h1 , h2 , h3):
    h11 = itertools.accumulate(h1)

    h22 = itertools.accumulate(h2)

    h33 = itertools.accumulate(h3)

    equal = False
    while not equal:
        if h11[-1] == h22[-1] == h33[-1]:
            equal = True
            break
        else:
            if h11[-1] > h22[-1] and h11[-1] > h33[-1] and len(h11) != 0:
                h11.pop()
            elif h22[-1] > h11[-1] and h22[-1] > h33[-1] and len(h22) != 0:
                h22.pop()
            elif h33[-1] > h11[-1] and h33[-1] > h22[-1] and len(h33) != 0:
                h33.pop()

    return str(h11[-1])

if __name__ == '__main__':
    n1 , n2 , n3 = map( int , sys.stdin.readline().strip().split() )

    h1 = list( map( int, sys.stdin.readline().strip().split() ) )
    h2 = list( map( int, sys.stdin.readline().strip().split() ) )
    h3 = list( map( int, sys.stdin.readline().strip().split() ) )

    result = equalStacks(h1 , h2 , h3)

    _ = sys.stdout.write( result + '\n')

我只是在编辑器上复制了您的代码，首先我得到了它，这似乎不正确：
