首先，切换文件路径到所在文件夹

然后，将txt文件内容按行读取，写入到all.txt

def txtcombine():    files=glob.glob('*.txt')    all = codecs.open('all.txt','a')   #a代表追加    for filename in files:        print(filename)        fopen=codecs.open(filename,'r',encoding='utf-8')        lines=[]        lines=fopen.readlines()        fopen.close()        for line in lines:            for x in line:                all.w

#读取为DataFrame格式 

all1 = pd.read_csv('all.txt',sep=' ',encoding='GB23 保存为csv文件

#保存为csv格式        all1.to_csv('all.csv',encoding='GB2312')    return allif __name__=='__main__':    txtcombine()
