Note: This method only computes the relative path. This includes the Dockerfile itself and the context of the Dockerfile during the build process. To follow along, load the sample files into a single directory. When writing a regular Python program (or pytest test) if it includes something like this: with open ( 'some/path/file.txt') as f : read_data = f. read () Then the path some/path/file.txt will be relative to the executor not relative to the Python file. if os.listdir is absolutely needed you can just convert it into string and feed the string-fied path into os.listdir. Syntax: os.path. os.listdir returns only the relative path of the files or folders with reference to dirPath, and os.path.isfile function needs the full path to check whether it is a file or not, hence we need to use os.path.join to combine the dirPath and the results of os.listdir to get the full path of either files or paths. 7 stars. Why not try out much superior alternative pathlib.Path? Invalid file path or directory path.
