Command summary

The new commands used in this program and others that may be useful. Select them below to learn more:

match, case, case _

match

Provides an alternative structure to `if, elif, else` and is used in situations where there are more than two possibilities. There are also more advanced uses of match that make it more useful than `if`. You need to be using Python 3.10 or higher to use the match command. Don’t forget the colon at the end of the match statement.

case

Is the value for the match command. Possibilities for the value can be separated with pipe characters: `|`. You can have as many case statements as you need. Don’t forget the colon at the end of the case statement.


case _

An underscore is a special condition that is the same as `else`. It captures anything else that was not matched by the previous case statements. Don’t forget the colon at the end of the case statement.

Questions to think about with this program to check your understanding:

Relation question

In line 25: `print(“Month”, month, “is in the”, season)` why is the word month written twice in this line, but it is only output once?

REVEAL ANSWER

“Month” in double quotes is a string, it is the actual word, “Month”. In contrast, month without the double quotes is a variable: an area in memory to hold data that can change. This is holding the name of the month the user inputs. E.g. “May”. As we want the word “Month” followed by the name of the month to be output we need both in the statement.

Approach question

How could line 8 be written using an `if` instead of `case`?

REVEAL ANSWER

if month == “December” or month == “January” or month == “February”:

Success Criteria

Change the program so that:

  1. The function `seasons` handles the input of the month as a number too. E.g. At the prompt, “Enter the month: “, the user could enter “5” for May instead.

Typical inputs and outputs from the program would be:

Enter the number of the month: 5

Month 5 is in the Spring

Help

Use the flowcharts if you need more support in understanding the steps required to meet the criteria. Use the Parsons code sorting exercise only if you are really stuck.

Evaluate


Run your code to check that your program has met the success criteria and produces the required output.

Enter the month: 1

Month 1 is in the Winter

Enter the month: September

Month September is in the Autumn

Enter the month: 8

Month 8 is in the Summer
