在一个目录中查文件 哈哈哈 这个是我自己写的 开心 好难。
def search_file(file_name,path): all_files = os.listdir(path) a = None for each in all_files: if each == file_name and a== None: return path else: if os.path.isdir(os.path.join(path,each)) and a== None: a = search_file(file_name,os.path.join(path,each)) if a != None : return a path = input('请输入待查找的初始目录:') file_name = input('请输入需要查找的目标文件:') print(search_file(file_name,path))

def search_file(path,target): all_files = os.listdir(path) for each in all_files: if os.path.isdir(os.path.join(path,each)) : a = search_file(os.path.join(path,each),target) else: if os.path.splitext(each)[1] in '.mp4,.rmvb,.avi,.mp3': target.write(os.path.join(path,each)) target.write('\n') f = open('vedioList.txt','w') path = input('请输入待查找的初始目录:') print(search_file(path,f))
啊啊啊 信心再次增强!!!
4: 对不起 信心没了 抄答案
