How does Python find the path to a file?The OS module makes it easy to find file paths in batches!

Python provides a very convenient way to find file paths, using the OS module in Python to find file paths. The OS module provides a series of functions for working with files and directories, and the following are common ways for Python to find file paths.

1.Use OSgetcwd() function to get the path to the current working directory. This path refers to the directory where you are currently running the python script. 

import oscurrent_dir = os.getcwd()print(current_dir)
2.Use OSpath.abspath() gets the absolute path to the file. 

import osfile_path = os.path.abspath("file.txt")print(file_path)
3.Use OSpath.dirname() to get the directory path of the file. 

import osfile_path = "/my/directory/file.txt"dir_path = os.path.dirname(file_path)print(dir_path)
4.Use OSwalk() traverses the directory and its subdirectories. 

import osdir_path = "/my/directory"for root, dirs, files in os.walk(dir_path): for file in files: file_path = os.path.join(root, file) print(file_path)

5.Use OSpath.The join() function can connect multiple path components to generate a complete file path. This function will automatically select the appropriate path separator depending on the operating system. 

import ospath = os.path.join('path', 'to', 'file.txt')print(path)
6.Use OSpath.The abspath() function can get the absolute path to a specified file or directory. 

import osabsolute_path = os.path.abspath('file.txt')print(absolute_path)
7.Use OSpath.The exists() function can check if a file or directory at a specified path exists. 

import ospath = 'file.txt'if os.path.exists(path): print(f' exists')else: print(f' does not exist')
Mastering the above methods can easily help you find the file path in python, so as to realize the batch operation of some files, in the actual office, can improve personal work efficiency, if you encounter problems in the process of learning Xi, you can leave a message in the comment area to solve your ** problem
