To get a list of all subdirectories in a directory, recursively, you can use the os.walk function. It returns a three tuple with first entry being all the subdirectories.You can use it as follows:import os subdirs = [x[0] for x in os.walk('.')] print(subdirs)You can also list the directories(immediate only) using the os.listdir function and filtering the list using the os.path.isdir function.For exampleimport os d = '.' subdirs = [os.path.join(d, o) for o in os.listdir(d) if os.path.isdir(os.path.join(d,o))]

The path of a current file is defined with the help of directory hierarchy; and it contains the backtracked path from the current file to the root directory this file is present in. For instance, consider a file “my_file” belongs to a directory “my_directory”, the path for this file is defined as given below ./my_directory/my_file The directory, sub-directory and the file are all separated using the “/” separator in the path. Therefore, to get current file's full path, you can use the os.path.abspath() function. If you want only the directory path, you can call os.path.dirname() method. Using os.path.abspath() Method ...

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable. An example of the __init__.py file:from math import sin from my_package import my_funcThe above code ensures that the imported functions are available in the package's modules when it is imported as it is defined ...

A directory is simply defined as a collection of subdirectories and single files; or either one of them. These subdirectories are separated using a “/” operator in a directory hierarchy. A directory hierarchy is constructed by organizing all the files and subdirectories within a main directory, also known as “root” directory. When the size of a directory is to be calculated, we will consider it as a root directory and calculate the individual sizes of all the files and subdirectories (if any) present in it. Hence, to get the size of a directory we must walk through the hierarchy to ... Read More
