ModuleNotFoundError: No module named 'compiler'

修改別人項目的時候出現的錯誤：ModuleNotFoundError: No module named 'compiler'

參考https://blog.csdn.net/w5688414/article/details/78489277已解決。

刪除from compiler.ast import flatten

添加以下代碼：

import collections
def flatten(x):
    result = []
    for el in x:
        if isinstance(x, collections.Iterable) and not isinstance(el, str):
            result.extend(flatten(el))
        else:
            result.append(el)
    return result
 
print(flatten(["junk",["nested stuff"],[],[[]]]))
