Python match-case construct

In Python, since version 3.10, there is a special construct match-case, which is used to select one value from a range of values. Its syntax is:

match varuable:
	case 'value1':
		'''
			here is the code that will be executed
			if the variable has the value 1
		'''
	case 'value2'
		'''
			here is the code that will be executed
			if the variable has the value 2
		'''
	case _:
		'''
			here is the code that will be executed
			if the value does not match anything
		'''

Let us have a variable tst:

tst = 'a'

Let's write down in the condition the different options that the variable can take:

match tst:
	case 'a':
		print('a')
	case 'b':
		print('b')
	case _:
		print('tst is unknown')

Also, using the operator |, you can specify a selection of the required values in each variant:

match tst:
	case 'a' | 'c':
		print('a or c')
	case 'b' | 'd':
		print('b or d')
	case _:
		print('tst is unknown')

Let the variable num store one of the numbers: 1, 2, 3 or 4, containing the season number. Print the name of the season contained in the number.

Let the variable num store a month number from 1 to 12. Print the name of the season corresponding to this month.
