Python中执行系统命令常见方法有两种:两者均需 import os os.system 仅仅在一个子终端运行系统命令,而不能获取命令执行后的返回信息 system(command) -> exit_status Execute the command (a string) in a subshell. 如果再命令行下执行,结果直接打印出来 >>> os.system('ls') 04101419778.CHM bash document m...
如果想获取返回的结果,需要结合print 操作,执行流程如下: system(command) -> exit_status Execute the command (a string) in a subshell. 1. 2. 2、os.popen 也是os模块下的一个函数,示例如下: >>> import os >>> os.popen('ls') >>> os.popen('ls').readlines() ['binn', 'etcn', 'games...
``` # Python script to execute SQL queries on a database import sqlite3 def execute_query(connection, query): cursor = connection.cursor() cursor.execute(query) result = cursor.fetchall() return result ``` 说明: 此Python脚本是在数据库上执行SQL查询的通用函数。您可以将查询作为参数与数据库连...
os.system(cmd): 该方法在调用完shell脚本后,返回一个16位的二进制数,低位为杀死所调用脚本的信号号码,高位为脚本的退出状态码,即脚本中“exit 1”的代码执行后,os.system函数返回值的高位数则是1,如果低位数是0的情况下,则函数的返回值是0×100,换算为10进制得到256。

1. 使用os模块的system函数: “`python import os result = os.system(“command”) “` 这种方法会直接执行命令,并返回命令的退出状态码。如果命令成功执行,返回值为0;如果命令执行失败,返回值为非零。 2. 使用subprocess模块的check_output函数: “`python ...
