Whereas before, you had to format strings in one of these ways (among other more verbose ways):&lt;p&gt;&lt;pre&gt;&lt;code&gt;  &amp;quot;My name is {} and I am {} years old&amp;quot;.format(name, age)

  &amp;quot;My name is %s and I am %s years old&amp;quot; % (name, age)

  &amp;quot;My name is {name} and I am {age} years old&amp;quot;.format(name=name, age=age)
&lt;/code&gt;&lt;/pre&gt;
Now, we can finally use f-strings, where anything in brackets is eval&amp;#x27;ed, with the result subbed in:&lt;p&gt;&lt;pre&gt;&lt;code&gt;  f&amp;quot;My name is {name} and I am {age} years old.&amp;quot;&lt;/code&gt;&lt;/pre&gt;</text></item></parent_chain></comment><story><title>Python 3.6.0 released</title><url>https://mail.python.org/pipermail/python-list/2016-December/717624.html</url></story>

... but I always felt a little guilty like this is some kind of dynamic-programming-on-steroids trick that I should use sparingly.</text><parent_chain><item><author>chrisshroba</author><text>I absolutely LOVE format strings.
