subprocess.run([“ls”, “-l”, “/dev/null”], stdout=PIPE, stderr=PIPE) “`事实上,如果我们查看引入该功能的 python-3.7 版本的源代码,我们会在 源代码 [GitHub] 中看到:if capture_output: if ('stdout' in kwargs) or ('stderr' in kwargs): raise ValueError('stdout and stderr ...
capture_output 参数是 subprocess.run() 函数在 Python 3.7 及以上版本中引入的,用于捕获子进程的输出(标准输出和标准错误输出)到 CompletedProcess 实例的 stdout 和stderr 属性中。这个参数简化了之前需要分别设置 stdout=subprocess.PIPE 和stderr=subprocess.PIPE 并从返回的 Popen 对象中读取输出的过程。 2. 检查...
然后,你可以从返回的`subprocess.CompletedProcess`对象中获取输出。 以下是一个示例³: ```python import subprocess # 向子进程提供输入 input_data = b"input data" # 运行脚本并捕获输出 result = subprocess.run(["python", "script.py"], input=input_data, capture_output=True) # 获取子进程的输出结...
I am using python 3.12.4 on windows 10 and when callingsubprocess.run("powershell", shell=True, capture_output=True, timeout=1)code execution seems to suspend indefinetly as the process now accepts the user input and interprets it. This behaviour matches the one described in#81605despite it...
在Python的`subprocess`模块中,`capture_output`参数是一个布尔值,用于指定是否捕获已执行子进程的标准输出和标准错误流。 当`capture_output`设置为`True`时,子进程的标准输出和标准错误流将被捕获并在`CompletedProcess`对象的`stdout`和`stderr`属性中分别返回为`bytes`对象。这允许你访问子进程产生的输出和错误信...

subprocess.run() 运行一些 shell 命令。 我还想捕获 shell 命令的输出。 当我使用 capture_output=False 运行命令时,它似乎运行良好。 但是当我将其切换到 True时,我收到错误。 import subprocess # runs just fine subprocess.run("git --version", capture_output=False) # throws error subprocess.run("...
