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:

Printing Number Variables Within Sentences

To join strings and number values then you must use a comma as a plus will not work:




You need to use a comma before and after each variable.

Practice Task 2

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.

Example solution:

Using f-Strings

Another method of using variables within a printed sentence is to use f-strings.

Type the letter f before your output and place your variable names in curly brackets - { }

Variables of any data type can be used with f-strings.


Practice Task 3

1. Create three variables:

  • movie_name

  • actor

  • year

2. Use an f-string to print a sentence that uses all three variables.
