Count files in Folder by Python Programming
提问by Fahadkalis
I am trying to count number of files in my folder (/Home/python) for that reason I make a short program
我正在尝试计算文件夹 (/Home/python) 中的文件数，因此我制作了一个简短的程序
import os.path
path = '/Home/python'
num_files = len([f for f in os.listdir(path)if os.path.isfile(os.path.join(path, f))])
but it is given me an error like that
但它给了我这样的错误
Traceback (most recent call last):
File "count_number_of_files_folder.py", line 3, in <module>
num_files = len([f for f in os.listdir(path)if os.path.isfile(os.path.join(path, f))])
OSError: [Errno 2] No such file or directory: '/Home/python'
Guys can you plz help me to make it bug free program. Thank You
伙计们，你能帮助我让它成为无错误程序。谢谢你

Try this instead
试试这个
import os.path
path = os.getenv('HOME') + '/python'
num_files = len([f for f in os.listdir(path)if os.path.isfile(os.path.join(path, f))])
This is because you are not in /home/python. You are actually in your home directory which is /home/$USER/python. If you do the following, in a terminal, you will see where you are.
这是因为您不在 /home/python 中。您实际上位于 /home/$USER/python 的主目录中。如果您执行以下操作，在终端中，您将看到您所在的位置。
cd ~/python && pwd

import glob, os
file_count = 0
WorkingPath = os.path.dirname(os.path.abspath(__file__))
for file in glob.glob(os.path.join(WorkingPath, '*.*')):
file_count += 1
Just stick the source for that into whatever directory you are counting files in. This only counts files not folders.
只需将其源代码粘贴到您计算文件所在的任何目录中即可。这仅计算文件而非文件夹。

It needs to be a lowercase hfor ubuntu homeand you also need to supply your username, so either use path = "/home/user_name/python"or os.path.expanduser.
h对于 ubuntu home，它必须是小写字母，并且您还需要提供您的用户名，因此可以使用path = "/home/user_name/python"或os.path.expanduser。
os.path.expanduserwill return something like /home/username/python:
os.path.expanduser将返回类似/home/username/python：
import os
path = os.path.expanduser("~/python")
num_files = len([f for f in os.listdir(path)if os.path.isfile(os.path.join(path, f))])

I think this is the easiest way:
我认为这是最简单的方法：
import os
img_folder_path = 'C:/FolderName/FolderName2/IMG/'
dirListing = os.listdir(img_folder_path)
print(len(dirListing))
