Python Python Basics (2015) Python Data Types String Formatting

How are you supposed to use the .format() method without printing?

status_message = “Hey there are 7 pancakes there.” status_message = “Hey there are {} pancakes there.” print(status_message) => Hey there are {} pancakes there. print(status_message.format(2)) = > Hey there are 2 pancakes there.

I thought this was the basic method we had to use for this part. However, the question is asking me to use the .format() method without the 'print'. What am I supposed to do?

strings.py 
name = 'Yungi'
subject = "Treehouse loves {}"
subject = "Treehouse loves {Yungi}"

Here's an example of using string formatting outside of a print statement. You can think of it as a way to generate strings, using variables, which can then be used later on just as you would with any other string. Below, imagine you had to write a greeting for many people and store it somewhere to greet them later (dumb example).

Python 3.5.2 |Anaconda custom (64-bit)| (default, Jul 2 2016, 17:52:12) [GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin Type "help", "copyright", "credits" or "license" for more information.

>>> people = ['Jeff', 'Chance', 'Michelle', 'Scout']
>>> messages = ["Hi, {}".format(x) for x in people]
>>> messages
['Hi, Jeff', 'Hi, Chance', 'Hi, Michelle', 'Hi, Scout']
>>>

A more common example, let's say you have a URL:

somedomain.com/?=phrase&items=100&format=json

Say you were getting JSON data for 10 different phrases

You could use a similar pattern: phrases = ['dog', 'cat', 'bird', '......] urls = ["somedomain.com/?={}&items=100&format=json".format(x) for x in people]

Then you could get the JSON data for each url in your list of URLs.
