I need to iterate through all .asm
files inside a given directory and do some actions on them.
How can this be done in a efficient way?
Original answer:
import os
for filename in os.listdir(directory):
if filename.endswith(".asm") or filename.endswith(".py"):
# print(os.path.join(directory, filename))
continue
else:
continue
Python 3.6 version of the above answer, using os
- assuming that you have the directory path as a str
object in a variable called directory_in_str
:
import os
directory = os.fsencode(directory_in_str)
for file in os.listdir(directory):
filename = os.fsdecode(file)
if filename.endswith(".asm") or filename.endswith(".py"):
# print(os.path.join(directory, filename))
continue
else:
continue
Or recursively, using pathlib
:
from pathlib import Path
pathlist = Path(directory_in_str).glob('**/*.asm')
for path in pathlist:
# because path is object not string
path_in_str = str(path)
# print(path_in_str)
rglob
to replace glob('**/*.asm')
with rglob('*.asm')
Path.glob()
with '**/'
added in front of the given relative pattern:from pathlib import Path
pathlist = Path(directory_in_str).rglob('*.asm')
for path in pathlist:
# because path is object not string
path_in_str = str(path)
# print(path_in_str)
