Python Glob Module
The glob module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell, although results are returned in arbitrary order.
Importing the Module
import globBasic Usage
The glob.glob() function returns a list of files that match the pattern.
import glob
# Find all .py files in the current directory
files = glob.glob('*.py')
print(files)Wildcards
*: Matches zero or more characters.?: Matches exactly one character.[]: Matches a range of characters.
import glob
# Find files starting with 'file' and ending with .txt
print(glob.glob('file*.txt'))
# Find files with a single character name
print(glob.glob('?.txt'))
# Find files with a number range
print(glob.glob('[0-9].txt'))Recursive Search
If recursive is true, the pattern ** will match any files and zero or more directories, subdirectories and symbolic links to directories.
import glob
# Find all .txt files in current directory and subdirectories
files = glob.glob('**/*.txt', recursive=True)
print(files)Iterators
glob.iglob() returns an iterator which yields the same values as glob() without actually storing them all simultaneously.
import glob
for file in glob.iglob('**/*.py', recursive=True):
print(file)
