Filename casing changed to lower when argument for Python Glob module is taken from list

The Python glob module uses the file system's case sensitivity rules when matching file names. If the file names in your list have different casing than what is stored on the file system, the glob module may not match them correctly.

To overcome this issue, you can ensure that the file names in your list match the casing of the file names on the file system. Here are a few approaches you can try:

1. Update the file names in your list to match the casing of the file names on the file system. Use the correct casing for each character in the file names.

2. Use the os.listdir function instead of the glob module. The os.listdir function returns the file names as they are stored on the file system, without performing any casing changes.

   pythonCopy code
   import os
   
   
   
   directory = '/path/to/directory'
   
   file_list = os.listdir(directory)
   
   
   
   for filename in file_list:
   
       # Process each file name
   
       print(filename)
   
   

   This way, you can retrieve the file names in their original casing.

3. If you need more advanced pattern matching capabilities, consider using a library like pathlib or fnmatch instead of glob. These libraries provide more control over pattern matching and casing handling.

   Here's an example using the pathlib module:

   pythonCopy code
   import pathlib
   
   
   
   directory = pathlib.Path('/path/to/directory')
   
   file_list = [str(path) for path in directory.iterdir()]
   
   
   
   for filename in file_list:
   
       # Process each file name
   
       print(filename)
   
   

   The pathlib.Path object preserves the casing of the file names, allowing you to process them as they are stored on the file system.

By ensuring that the file names in your list match the casing of the file names on the file system, you can avoid issues with casing changes when using the glob module or other file name matching mechanisms.
