由于我没有体验过PowerShell，我不会理解他们用脚本调用的方法。

我自己仍然是PowerShell的新手，因此无法具体回答导致错误的原因，但我认为我找到了解决方案。它似乎只有Excel转换。 Word和PPT转换完美无瑕。我已经更改了该部分的代码，现在似乎正在运行：

def printWord(begin, mid, end, r):
    print(begin, end="")
    for i in range(r+1):
        print(mid, end="")
    print(end)
begin = input("Enter your beginning.\t")
mid =input("Enter your middle.\t")
end = input("Enter your ending.\t")
r = int(input("How many times?\t"))

printWord(begin, mid, end, r)
