こんにちは！<\/P>

私はpythonでリアルタイムデータを更新するコースを受講しました。コースの後半では、ウェブマップのオンラインフィーチャサービスを更新することになっていました。しかし、pythonコマンドプロンプトでスクリプトを実行したときにFileNotFound error が発生しました：<\/P>

"FileNotFoundError: [WinError 3] システムは指定されたパスを見つけることができません: 'C:\\Users\\user\\AppData\\Local\\Temp\\tmpfesd0bnq\\p20\\live.gdb'"<\/P>

修正方法について助けが必要です。<\/P>

添付したのは私が書いたスクリプトです。<\/P>

ありがとうございます。<\/P><\/BODY><\/HTML>

When you specify the file name "filename.ext" while read  file, you are providing the open() function with a relative path. This means that the file you want to read is located in the current working directory.

file = open('filename.ext') //relative path

In the above code, you are not giving the full path to a file to the open() function, just its name - a relative path. The error “FileNotFoundError: [Errno 2] No such file or directory” is telling you that there is no file of that name in the working directory. So, try using the exact, or absolute path.

file = open(r'C:\path\to\your\filename.ext') //absolute path

In the above code, all of the information needed to locate the file is contained in the path string - absolute path.

If the full path to the file is not provided, the python file path is interpreted relative to the current working directory. This is the directory from which the program was started. For this to work, the directory containing the python executable must be in the PATH environment variable, which contains directories automatically searched for executables when a command is entered. To access a file in a different directory, you must either specify a relative path between the files or use an absolute path for one of them.
