fileName = g.enterbox(msg='请输入您要查找的文件名：',default='path.txt')

def searchFile(fileName,searchPath):
    file_list = []
    for path,dirnames,filenames in os.walk(searchPath):
        for filename in filenames:
            if fnmatch.fnmatch(fileName,filename):

                path1=os.path.join(path,filename)
                file_list.append(path1)
    if len(file_list) != 0:
        return file_list
    return -1 

answer = searchFile(fileName,searchPath)
if answer == -1:
    g.msgbox("查无此文件",'查找错误')
else:
    g.msgbox(answer,'返回路径')
