Music.extend( (os.path.join(root,f) for f in files if f.endswith('.mp3')) ) Movie.extend( (os.path.join(root,f) for f in files if f.endswith('.mp4')) ) First, import the os.path standard library: import os. # root is the dir we are currently in, f the filename that ends on. 1) Using os.path.exists () function to check if a file exists To check if a file exists, you pass the file path to the exists () function from the os.path standard library.

# files: then it steps into each of the dirs and does the same. , which is passed as an argument to os.listdir(), signifies. # including the directory its in as root, all subdirs in dirs and all files in Pythons os module provides a function that gets a list of files or folders in a directory.

# os.walk recurses into subdirectories, it returns a generator for each directory See this aproach with os.walk and list-comprehensions to filter the files: import osĬreate files: dirs = Os.chdir(os.path.join(self.path,directory)) If os.path.splitext(os.path.join(self.path,item)) in : If os.path.isdir(os.path.join(self.path,d)):Įlif os.path.isfile(os.path.join(self.path,d)): It works well with files located in home directory but when I want it to check other directories to see if there is any file there or not, it cant work.

The general syntax for the find () method looks something like this: stringobject.find ('substring', startindexnumber, endindexnumber) string. It takes a substring as input and finds its index - that is, the position of the substring inside the string you call the method on. Hi guys in the script below I tried to first, list every file and directory in my home directory then check if there is any file with specific extension e.g(.py. The find () string method is built into Python's standard library.
