In practice, there are times when your list might contain values you’d want to exclude, like None or empty strings. Here’s how I’d address such edge cases explicitly:
my_list = ['a', '', None, 'b', 'c']
result = ','.join(x for x in my_list if x)
print(result) # Output: 'a,b,c'
By filtering out None and empty values before joining, this method gives you more control over the output. It’s especially useful when dealing with user-input data or processing dynamic content.
And for more complex conditions, you can extend the filter logic further. Just another handy way to handle a python list to string with commas.
