Selecting multiple files according to timestamp with glob
Question:
I have a directory with 7000 daily .tif files, spanning from 2002 to 2022. Each file has a respective indication of its timestamp, in the yyyy/mm/dd format, as: My_file_20020513.tif
I’m trying to select the file paths according to their respective month, i.e. all files from January, all files from February, and so on.
I thought using a simple wildcard showing my month of interest would solve the problem, such as:
january_files = glob.glob('My_folder/My_file_*01*.tif')
But this ended up selecting all files that have a number 01 on its string, such as all the first days of a month, and even October’s days that starts with a 1.
Is there a way I can use glob for selecting the file paths for a specific month only?
Answers:
Use ? to match a single character. Then you can use four ? to match any year.
january_files = glob.glob('My_folder/My_file_????01*.tif')
