Python 3.6.0 released
I absolutely LOVE format strings. Whereas before, you had to format strings in one of these ways (among other more verbose ways):<p><pre><code>  "My name is {} and I am {} years old".format(name, age)

  "My name is %s and I am %s years old" % (name, age)

  "My name is {name} and I am {age} years old".format(name=name, age=age)
</code></pre>
Now, we can finally use f-strings, where anything in brackets is eval'ed, with the result subbed in:<p><pre><code>  f"My name is {name} and I am {age} years old."</code></pre>
