subprocess.Popen双开adb窗口
时间: 2024-06-15 18:02:49 浏览: 22
subprocess.Popen是Python中的一个模块,用于执行外部命令并与其进行交互。而adb是Android Debug Bridge的缩写,是Android开发工具包中的一个命令行工具,用于与Android设备进行通信。
要双开adb窗口,可以使用subprocess.Popen来执行两个adb命令,并分别打开两个终端窗口。下面是一个示例代码:
```python
import subprocess
# 执行第一个adb命令,打开第一个终端窗口
p1 = subprocess.Popen(['adb', 'command1'], shell=True)
# 执行第二个adb命令,打开第二个终端窗口
p2 = subprocess.Popen(['adb', 'command2'], shell=True)
```
在上面的代码中,`command1`和`command2`是你要执行的具体adb命令。通过调用`subprocess.Popen`函数,并传入命令参数列表,可以启动两个独立的adb窗口。
请注意,这只是一个示例代码,你需要根据实际情况修改`command1`和`command2`的值,以及其他可能需要的参数。

subprocess.Popen subprocess.run
subprocess.Popen and subprocess.run are both modules in Python's subprocess module that are used for running external commands. Here's a brief explanation of each:
1. subprocess.Popen: This function is used to create a new process and execute a command within it. It provides more flexibility and control over the execution process. Popen returns a Popen object, which allows you to interact with the running process, such as reading its output or terminating it.
Example usage:
```python
import subprocess
# Run a command and get its output
result = subprocess.Popen(['ls', '-l'], stdout=subprocess.PIPE)
output = result.communicate()
print(output.decode('utf-8'))
```
2. subprocess.run: This function is a higher-level convenience function introduced in Python 3.5. It is used to run a command and wait for it to complete. It returns a CompletedProcess object that provides information about the completed process, such as return code and output.
Example usage:
```python
import subprocess
# Run a command and get its output
result = subprocess.run(['ls', '-l'], capture_output=True, text=True)
print(result.stdout)
```
Both functions can be used to execute external commands, but the choice between them depends on your requirements. Popen offers more flexibility, while run provides a simpler and more straightforward way to execute commands.
subprocess.Popen
subprocess.Popen()是Python中用于执行外部命令的函数。它允许你在Python脚本中启动一个新的进程,并与其进行交互。下面是两个关于subprocess.Popen()的例子:
1. 使用subprocess.Popen()执行adb shell命令,并输出结果:
```python
import subprocess
# 进入shell
s = subprocess.Popen("adb shell", stdout=subprocess.PIPE, stdin=subprocess.PIPE)
# 再次输入指令ps -A
s.stdin.write(b"ps -A")
# 关闭输入
s.stdin.close()
# 输出每行的数据
for i in s.stdout.readlines():
print(i)
```
2. 使用subprocess.Popen()执行df -h命令,并获取进程信息:
```python
import subprocess
p = subprocess.Popen("df -h", shell=True, stdout=subprocess.PIPE)
# 打印进程信息
print(p)
```
