How to remove the extra commas from the list of email addresses

No need for regular expressions. Use .split(',') to split into a list of strings.

email_lst = email_addr.split(',')

Then join with comma, but filter out blank values

email_addr2 = ",".join(e.strip() for e in email_lst if e.strip())
# 'test@domain.com,test1@domain.com,test2@domain.com'

In Python 3.8+, you can use the walrus operator to avoid calling .strip() twice:

email_addr2 = ",".join(e for ee in email_lst if (e := ee.strip()))

[int(s.replace(',','')) for s in l]
# [10, 1000, 51000, 500, 63000]
