os.popen(command [, mode [, bufsize]]) command是需要执行的系统命令 mode是读取命令输出的模式(默认为“r”) bufsize是读取缓冲区的大小(默认为-1) 调用os.popen()函数后,可以通过read()、readline()、readlines()等方法来读取命令的输出结果。 优点: 可以获取系统命令的输出结果 缺点: 无法对命令执行过程...

要使用csv模块读取一个 CSV 文件,首先使用open()函数 ➋ 打开它,就像您处理任何其他文本文件一样。但不是在open()返回的File对象上调用read()或readlines()方法,而是将其传递给csv.reader()函数 ➌。这将返回一个reader对象供您使用。注意,您没有将文件名字符串直接传递给csv.reader()函数。

os.popen(command[, mode[, bufsize]]) 1. os.system(cmd)或os.popen(cmd),前者返回值是脚本的退出状态码,后者的返回值是脚本执行过程中的输出内容。 a = os.popen("lsb_release -a") print(a.read()) a= os.popen("ifconfig") print(a.read()) ...
