Solved Trouble with player name replacement (Python)

Evening. I developpe very much in other languages - but I never ever touched python or lua.
My bad, because now I even don't know how to write a simple and stupid if-else-block!

Original:

Code:

self.say(MSG['JOIN MESSAGE'].format(**ply.__dict__), COLORS['JOIN MESSAGE'], uid)

I want to replace the player name (ply.__dict__) by another word but it doesn't work and I cannot find why

Code:

if PLUGIN['ENABLE ANONYMOUS JOIN/LEAVE MESSAGE']:
  pname = "Someone"
else:
  pname = ply.__dict__self.say(MSG['JOIN MESSAGE'].format(**pname), COLORS['JOIN MESSAGE'], uid)

The server join message looks like this:

Code:

"<lime>{username}<end> from <orange>{country}<end> joined the server."

Can someone help me please?

Everytime someone joins the server, it's written to the chat with player-name.

I wanted to have a option like "ENABLE ANONYMOUS JOIN/LEAVE MESSAGE". Like this you can put the following to python.py in joining_messages():

Code:

#Join message
# ...userdata = ply.__dict__
   
if PLUGIN['ENABLE ANONYMOUS JOIN/LEAVE MESSAGE']:
  userdata["username"] = "Someone"self.say(MSG['JOIN MESSAGE'].format(**userdata), COLORS['JOIN MESSAGE'], uid)

If this option is enabled, the server writes now "Someone joined the server, from -country-" to the chat instead of the username.
