sumstats.py clump ##Error

order:
python sumstats.py clump

--exclude-ranges ['6:25119106-33854733', '8:7200000-12500000']
When I did clump, the following error occurred：
ValueError: Unable to interpret exclude range "[6:25119106-33854733,", chr:from-to format is expected.

I can't find the reason for the error, so I would like to ask you for help and hope to get your reply.
