Python 1d - Using Variables
Printing Variables Within Sentences
Join sentences and variables together using a plus symbol (+). Joining sentences together like this is called concatenation.
=
Remember to use speech marks for your printed statements but print the variable name to display the variable value.
=
You need to use the + symbol before and after each variable.
Practice Task 1
1. On line 1 write a variable with the name sandwich and the value of a sandwich filling.
2. On line 2 print a sentence that uses the variable name sandwich.
3. On line 3 change the variable sandwich to equal a different filling.
4. On line 4 print the same sentence as line 2.
Example solution:

1. Create a variable called bottles and give it the value 99.
2. print a sentence that uses the variable name.
3. Change the variable value to 98.
4. print the same sentence again.
