如何停止python递归 [英] How to stop python recursion

问题描述

我做了一个递归搜索文件的函数，我希望它在找到第一个文件时停止递归:

I made a function that searches files recursively and I want it to stop recursion when the first file is found:

def search_file(path):
    for name in os.listdir(path):
        sub = os.path.join(path, name)
        if os.path.isfile(sub):
            return sub#And break recursion
        else:
            search_file(sub)

推荐答案

返回一个标志，表明文件是否被找到.当你调用search_file时，如果返回值为True则返回.

Return a flag that says whether the file was found. When you call search_file, return if the return value is True.
