Question

我有两个文件：

D:/Users/SPate233/Downloads/NS dashboard/sql_query\Book1.csv
D:/Users/SPate233/Downloads/NS dashboard/sql_query\Book2.csv

我想将它们添加到一个列表中-

输出

files = ["D:/Users/SPate233/Downloads/NS dashboard/sql_query\Book1.csv", "D:/Users/SPate233/Downloads/NS dashboard/sql_query\Book2.csv"]

代码-

        path = '/nsmnt/NS_Exec_DSHBD/output/*.csv'
        files = glob.glob(path)
        file_list = []
        for name in files:
            size = os.stat(name).st_size
            if size <= 5:
                print("file %s is empty" %name)
                log.info("file %s is empty" %name)
                file_list = file_list.append(name.split(','))

错误：-

'NoneType' object is not iterable

Answer 1

    path = '/nsmnt/NS_Exec_DSHBD/output/*.csv'
    files = glob.glob(path)
    file_list = []
    for name in files:
        size = os.stat(name).st_size
        if size <= 5:
            print("file %s is empty" %name)
            log.info("file %s is empty" %name)
            file_list += name.split(',')

请注意，name.split（'，'）将生成一个列表，append用于单个值+ =表示lista = lista + listb，换句话说，将name.split的样式添加到file_list

Answer 2

file_list = [i for i in glob.glob(path) if os.stat(i).st_size <= 5]

如何在python中的单个列表中添加多个值？
