python - 命令提示符说文件存在时无法找到文件

Question

所以我有一个 .py 脚本，我试图在命令提示符或 anaconda 提示符下运行。如果我运行python filename.py，它会给我这个错误： python: can't open file 'C:\Users\tform\Documents\AirSim\CapstoneAPI.py': [Errno 2] No such file or directory。

我不确定如何解决此问题，因为该文件位于该位置。我需要搞乱一些设置吗？

我使用 Visual Studio 2019 作为我的 Python IDE。

    print("imu_data: %s" % s)

    #print("Altitude: %s\nLatitude %s\nLongitude %s" %(alt,lat,lon) )
    if False:
      break

正如人们所说，当我们python name.py在终端中使用“”命令运行一个python脚本时，我们需要进入这个python文件的父文件夹才能找到它。

解决方案：我们可以使用“cd”进入python文件的父文件夹：（请进入你的文件夹“AirSim”。）
