Python-python中使用递归遍历目录与文件问题

Question

def cdGrep(keyword,filepath):
    filelist = os.listdir(filepath)

    for cdc in filelist:        
        if os.path.isdir(cdc):
            filepath2 = os.path.join(filepath,cdc)
            cdGrep(keyword,filepath2)
        elif '.txt' in cdc:
            f = open(filepath+'\'+ cdc)
            for line in f.readlines():
                linelower = line.lower()
                if keyword in linelower:                    
                    print '您查找的关键词在%s中找到'% (filepath+'\'+cdc)
                    print line
                f.close()
if __name__ == '__main__':
    keword = raw_input('请输入想要查询的关键字')
    pw = os.getcwd()
    cdGrep(keword,pw)

Answer 1

因为你在判断是否目录的时候写错了，你错误的判断了

if os.path.isdir(cdc):

其实应该判断的是

 if os.path.isdir(os.path.join(filepath,cdc)):
