​​（一）Variables and Data Types

​​1.  Variables

• ​​A variable stores a piece of data, and gives it a specific name.

• ​​[ 範例 1 ] Variables

• ​​Set the variable my_variable equal to the value 10.

​​# Write your code below!

​​my_variable = 10

​​ 

​​ 

​​2.  Booleans

• ​​A boolean is like a light switch. It can only have two values. Just like a light switch can only be on or off, a boolean can only be True or False.

• ​​[ 範例 2 ] Booleans

• ​​Set the following variables to the corresponding values:

1. ​​my_int to the value 7

2. ​​my_float to the value 1.23

3. ​​my_bool to the value True

​​# Set the variables to the values listed in the instructions!

​​ 

​​my_int = 7        # interger

​​my_float = 1.23   # float

​​my_bool = True    # boolean
