+
+For some reason, I wanted to rename all the chains in a PyMOL session to be unique once. Here's a script to do so.
+
+```python
+from string import ascii_uppercase
+
+i = 0
+
+for model in cmd.get_object_list():\
+    if i > 25:\
+        chain_id = "A" + ascii_uppercase[i-26]\
+    else:\
+        chain_id = ascii_uppercase[i]\
+    cmd.alter(model, f"chain=\"{chain_id}\"")\
+    i = i + 1
+```
