You can hit Run Code and Submit Answer as often as you want. If you're stuck, you can click Get Hint, and ultimately Get Solution.

You can also use the IPython Shell interactively by simply typing commands and hitting Enter. When you work in the shell directly, your code will not be checked for correctness so it is a great way to experiment.

In Python, a variable allows you to refer to a value with a name. To create a variable use =, like this example:

\n
x = 5\n
\n

You can now use the name of this variable, x, instead of the actual value, 5.

Remember how you calculated the money you ended up with after 7 years of investing $100? You did something like this:

\n
100 * 1.1 ** 7\n
\n

Instead of calculating with the actual values, you can use variables instead. The savings variable you've created in the previous exercise represents the $100 you started with. It's up to you to create a new variable to represent 1.1 and then redo the calculations!

In the previous exercise, you worked with two Python data types:

\n\n

Next to numerical data types, there are two other very common data types:

To find out the type of a value or a variable that refers to that value, you can use the type() function. Suppose you've defined a variable a, but you forgot the type of this variable. To determine the type of a, simply execute:

\n
type(a)\n
\n

We already went ahead and created three variables: a, b and c. You can use the IPython shell to discover their type. Which of the following options is correct?

Hugo mentioned that different types behave differently in Python.

\n

When you sum two strings, for example, you'll get different behavior than when you sum two integers or two booleans.

\n

In the script some variables with different types have already been created. It's up to you to use them.

Using the + operator to paste together two strings can be very useful in building custom messages.

\n

Suppose, for example, that you've calculated the return of your investment and want to summarize the results in a string. Assuming the integer savings and float result are defined, you can try something like this:

\n
print(\"I started with $\" + savings + \" and now have $\" + result + \". Awesome!\")\n
\n

This will not work, though, as you cannot simply sum strings and integers/floats.

\n

To fix the error, you'll need to explicitly convert the types of your variables. More specifically, you'll need str(), to convert a value into a string. str(savings), for example, will convert the integer savings to a string.

\n

Similar functions such as int(), float() and bool() will help you convert Python values into any type.

Now that you know something more about combining different sources of information, have a look at the four Python expressions below.\nWhich one of these will throw an error? You can always copy and paste this code in the IPython Shell to find out!
