DataFrame拼接的一种方式：

1. 使用列表，
2. 列表中的DataFrame合并

lists = [735,3665,4015,4043,4048,4126,4746,4908,4936,5091,5121,5261,6426,6453,6995,
         7162,7859,7879,7910,8215,8219,8378,8405,8434,8455]
frames = []
for list in lists:
    Location = '.../database/afdb/' #文件地址
    CSV_FILE_PATH = Location+'/afdb-label-'+str(list) + '.csv' # csv文件
    df = pd.read_csv(CSV_FILE_PATH)
    print(df.head(5))
    frames.append(df)  
result = pd.concat(frames)  #所有csv记录都会按照标签变为一个大的dataframe.
