+# Variables Lab
+
+### Introduction
+
+Now that you know about variables, you want to use them to associate them with some data.  Here, we will be using variables to store information related to a vacation that we would like to go on.
+
+Just as before, we ask you to run the code and ensure that it matches what is commented out.
+
+### Learning Objectives
+
+* Practice variable assignment in Python
+* Practice variable reassignment in Python
+
+### Assigning variables
+
+Assign a variable of `travel_month` equal to the string "January", as that is the month you would like to travel.
+
+
+```python
+travel_month = None
+```
+
+> We start by setting the variable equal to the data type None.  As you know, `None` represents the absence of a value.  And now you can take care of assigning the variable to something other than `None`.
+
+
+```python
+travel_month # "January"
+```
+
+Now let's assign a variable equal to the number of weeks that you would like to travel, 3. 
+
+
+```python
+number_of_weeks = None
+```
+
+
+```python
+number_of_weeks # 3
+```
+
+Now, you just learned that you can travel for a longer period of time.  So reassign the `number_of_weeks` variable equal to `5`.
+
+
+```python
+number_of_weeks # 5
+```
+
+Now that's more like it.
+
+### Summary
+
+Great! In this lab, you were able to get a sense how to store information in variables through assignment and reassignment.
