self.photo_dir = os.path.join(os.getcwd(), "photos")

这行代码是在Python中创建一个变量 `photo_dir`,它的值是当前工作目录下的一个名为 "photos" 的子目录的路径。`os.getcwd()` 函数会返回当前工作目录的路径,在这里是Python脚本正在运行的目录。`os.path.join()` 函数则用于将路径字符串连接起来,以确保适当的目录分隔符被使用。最终,`photo_dir` 变量将包含完整的路径,可以在程序中使用。

def plot(self): self.is_running = False pwd_path = os.path.abspath(os.path.join(os.getcwd(), "..")) script_path = os.path.join(pwd_path, 'callisto-test-tool\\algo_galileo_2e235eb933c9_deg90\\An_test') folder_path = os.path.join(pwd_path, 'callisto-test-tool\\source\\Test_Source_Data') os.chdir(script_path) os.system('powershell -Command "./csv_output.sh {0}"'.format(folder_path)) 怎么检测该段程序中powershell是否运行完毕
要检测该段程序中 `powershell` 是否运行完毕,可以使用 Python 的 `subprocess` 模块来代替 `os.system` 函数来运行 `powershell`,并使用 `communicate()` 方法来等待 `powershell` 进程结束。例如:
```
import subprocess
def plot(self):
self.is_running = False
pwd_path = os.path.abspath(os.path.join(os.getcwd(), ".."))
script_path = os.path.join(pwd_path, 'callisto-test-tool\\algo_galileo_2e235eb933c9_deg90\\An_test')
folder_path = os.path.join(pwd_path, 'callisto-test-tool\\source\\Test_Source_Data')
os.chdir(script_path)
cmd = 'powershell -Command "./csv_output.sh {0}"'.format(folder_path)
process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate() # 等待进程结束
if process.returncode == 0:
print('程序执行成功!')
else:
print('程序执行失败!')
```
这样就可以在程序执行完成后得到 `powershell` 进程的返回值,并根据返回值来判断程序是否执行成功。如果返回值为 0,则表示程序执行成功,否则表示程序执行失败。
