Bonjour je galère depuis ce matin à lancer un script 
le script:
!/usr/bin/env python3
# Author: AnalogMan
# Modified Date: 2019-09-07
# Purpose: Compress/Decompress DDSZ files for Switch
# Requirements: LZ4 (pip install lz4)
import sys, os, lz4.block, argparse
def main():
print('\n======== DDSZ Archive Tool ========\n\n')
if sys.version_info <= (3,1,0):
print('Python version 3.1.x+ needed to run this script.\n\n')
return 1
# Arg parser for program options
parser = argparse.ArgumentParser(description='Process DDSZ files with LZ4')
parser.add_argument('filename', help='Path to file')
# Check passed arguments
args = parser.parse_args()
# Check if required files exist
if os.path.isfile(args.filename) == False:
print('File cannot be found.\n')
return 1
filename = args.filename
# If DDSZ, decompress RAW block
if (filename[-4:].lower()) == 'ddsz':
try:
with open(filename, 'rb') as f:
compressed = f.read()
with open(filename[:-4] + 'dds', 'wb') as f:
f.write(lz4.block.decompress(compressed[4:]))
print('DDS file decompressed successfully.\n\n')
except:
print('Could not decompress file.\n\n')
# If DDS, compress to DDSZ and include filesize.
elif (filename[-3:].lower()) == 'dds':
try:
with open(filename, 'rb') as f:
decompressed = f.read()
with open(filename[:-3] + 'ddsz', 'wb') as f:
compressed = lz4.block.compress(decompressed)
f.write((len(compressed)+4).to_bytes(4, byteorder='little', signed=True))
f.write(compressed)
print('DDS file compressed successfully.\n\n')
except:
print('Could not compress file.\n\n')
else:
print('Unsupported file.\n')
return 1
if __name__ == "__main__":
main()Lorsque j'essaye de l’exécuter sur le shell j’obtiens cette erreur :
usage: DDSZ.py [-h] filename
DDSZ.py: error: the following arguments are required: filenameLe script vient pas de moi mais de cette page https://github.com/AnalogMan151/DDSZ_Tool/blob/master/DDSZ.py
Si quelqu'un aurait la gentillesse de m'aider
