@ca_puar, thanks for your helpful explanation! I will be saving that explanation to my notes.
In fact, in testing this feature, I observed that the
condition does not even have to be direclty related to the current element of the
list = ["@coolguy35", "#nofilter", "@kewldawg54", "reply", "timestamp", "@matchamom", "follow", "#updog"] usernames =  usernames = ["Trees" for a in list if len(list) > 4 ] Print(usernames)
['Trees', 'Trees', 'Trees', 'Trees', 'Trees', 'Trees', 'Trees', 'Trees']
Granted, the comprehension is not needed in this case, since the code could be generated with a simple for loop - but the code runs nevertheless.
This behavior is the same as “normal” loop, you can set different conditions and append what-ever you like. The list comprehension is just a short-hand in that regard
