Counting number of files using python in specific folder can be done using multiple ways. Some of these are mentioned below

| import os | |
| import glob | |
| print("*** Program Started ***") | |
| dir_name = 'C:/sample/' | |
| file_count = sum([len(files) for r, d, files in os.walk(dir_name)]) | |
| print('Number of Files using os.walk :', file_count) | |
| file_count = os.listdir(dir_name) | |
| print("Number of Files using listdir method#1 :", len(file_count)) | |
| file_count = len([name for name in os.listdir(dir_name) if os.path.isfile(os.path.join(dir_name, name))]) | |
| print("Number of Files using listdir method#2 :", file_count) | |
| file_count = [name for name in os.listdir(dir_name) if os.path.isfile(os.path.join(dir_name, name))] | |
| print("Number of Files using listdir method#3 :", len(file_count)) | |
| file_count = glob.glob(dir_name+'*.*') | |
| print("Number of Files using glob :", len(file_count)) | |
| print("*** Program Completed ***") |
Here is the output
*** Program Started *** Number of Files using os.walk : 7 Number of Files using listdir method#1 : 8 Number of Files using listdir method#2 : 7 Number of Files using listdir method#3 : 7 Number of Files using glob : 7 *** Program Completed ***
As you can see Number of Files using listdir method#1 are different, this is because, its counting a folder as a file.
