build array list - raopatwari - Jan-13-2018
I am writing function to return the list of files in unix directory. it is returning one file.
fl = []
WORKING_DIR='../'+sys.argv[1]+'/'
def find_case_insensitve(dirname, extensions):
WORKING_DIR='../'+sys.argv[1]+'/'
for filename in glob.glob(dirname):
base, ext = os.path.splitext(filename)
if ext.lower() in extensions:
fl.append(filename)
return list(fl)
print(fl)
fln=find_case_insensitve(WORKING_DIR+"*", ['.sql'])
print(fln)

Post your code again in Python code tags, so it will be readable. You can find help here.

Please, fix the indentation!

Quickest way to do this is to use
ctrl+shift+v when copy-pasting code.

Here is how I would do with pathlib
from pathlib import Path
def find_case_insensitive(dirname, extensions):
sufset = set(x.lower() for x in extensions)
return [f for f in Path(dirname).iterdir()
if f.suffix.lower() in sufset]
if __name__ == '__main__':
working_dir = Path('..')/'2018-01'
print(working_dir)
print(find_case_insensitive(working_dir, ['.py', '.csv']))Actually, it would be more python3ish to return an iterable from find_case_insensitive()instead of a list.

fl = []
fln = []
WORKING_DIR='../'+sys.argv[1]+'/'
def find_case_insensitve(dirname, extensions):
WORKING_DIR='../'+sys.argv[1]+'/'
for filename in glob.glob(dirname):
base, ext = os.path.splitext(filename)
if ext.lower() in extensions:
fl.append(filename)
#print(filename)
return list(fl)btw, I just started coding today in python. I guess I have to go long wayI can print(filename) when I comment return list(fl)
I want to use in the following way
fln=find_case_insensitve(WORKING_DIR+"*", [".sql"])
print(fln)
I will be using fln array in some other function

If you want to use glob library there is no need to use os.path.splitext to get the extension:
import glob
import sys
extensions = ('mp3', 'avi', 'mp4', 'mkv']
def find_media_files(path, files):
result = []
for ext in files:
pattern = path + '/*.' + ext # this will become /path/*.mp3 to search for.
found = glob.glob(pattern)
result.extend(found)
return result
my_collection = find_media_files(sys.argv[1], extensions)
for file_ in my_collection:
print(file_)
