+# Join A List Of Strings
+
+Though joining a list of strings in Python is a basic task, I wanted to write
+about it because it is backward from how it is done in Ruby (which trips me up
+every single time).
+
+So, in Ruby I would do the following:
+
+```ruby
+> character = ["Gimli", "Dwarf", "Fighter", "Lvl 23"]
+=> ["Gimli", "Dwarf", "Fighter", "Lvl 23"]
+> character.join(" ~ ")
+=> "Gimli ~ Dwarf ~ Fighter ~ Lvl 23"
+```
+
+Notice that I call
+[`join`](https://docs.ruby-lang.org/en/master/Array.html#method-i-join) on the
+list of strings, passing it the specific separator that I want to use.
+
+Python does it the other way around:
+
+```python
+>>> character = ["Gimli", "Dwarf", "Fighter", "Lvl 23"]
+>>> " ~ ".join(character)
+'Gimli ~ Dwarf ~ Fighter ~ Lvl 23'
+```
+
+The separator is the object that I call
+[`join`](https://docs.python.org/3/library/stdtypes.html#str.join) on, passing
+it the list of strings that I want to join.
