String '\' replace with '/'

a='C:/Users/me/Documents/PythonProjects/opencv/Train\11\00011_00014_00018.png'

I am running a for loop with variables such as a, that are strings. I intend to obtain the number 11 from the string above.

Using a.replace('\\,'/') , i get the exact same string back , that is, 'C:/Users/me/Documents/PythonProjects/opencv/Train\11\00011_00014_00018.png'

the only way i got it to work was with r/'C:/Users/me/Documents/PythonProjects/opencv/Train\11\00011_00014_00018.png'.replace('\\','/') but that does not work with variables i.e

r'a'.replace('\\','/')

its not like f-strings whereby i can parse variables as such f'{a}'

Thanks it worked !

root_dir = 'C:/Users/me/Documents/PythonProjects/opencv/Train'

all_img_paths = glob.glob(os.path.join(root_dir, '**.png'))

for img_path in all_img_paths:

try: img = preprocess_img(io.imread(img_path)) label = get_class(img_path)

to:

all_img_paths = glob.glob(os.path.join(os.path.normpath(root_dir), '**.png')) np.random.shuffle(all_img_paths)

I would instead recommend using os.path if your intention is to clean up or mutate filesystem paths

>>> import os
>>> a='C:/Users/me/Documents/PythonProjects/opencv/Train\11\00011_00014_00018.png'
>>> os.path.normpath(a)
'C:\\Users\\me\\Documents\\PythonProjects\\opencv\\Train\t\x0011_00014_00018.png'

Using os.path for path manipulation will generally behave correctly on different operating systems without you having to manually modify slashes, drive names, etc.
