Removing ragged lines in comments (Python)

Question

PyCharm can wrap lines of code that are longer than some number n (= 67 for this example), for example

# this is a really really really really really really really really really really really really really really long comment

becomes

# this is a really really really really really really really really
# really really really really really really long comment

** Is there a “reverse” functionality? * Often, due to the addition and removal of ideas from comments, they look very bad and are torn off like this:

# this is a the first idea.
# more bla bla, but still relating to first idea. bla bla.
# other bla bla.
# second brilliant idea. oh no, actually it breaks something, so watch out!

I would like Pycharm (possibly by including plugins) to reformat these comments (filling in the maximum line length) to look like this:

# this is a the first idea. more bla bla, but still relating to first 
# idea. bla bla. other bla bla. second brilliant idea. oh no, actually
# it breaks something, so watch out!

If Pycharm does not have this, do you know about a word processor that can do this?

This cannot be done in pycharm by default. There is no plugin. You can see the answer in a similar thread
