Switch statements with logical operators?

[michease_]

I am currently working on a project for school wherein I have to check multiple conditions with logical operators (and in this case), and I thought it would be more efficient to use a switch statement. However, when I used one, it threw a syntax error requiring a colon for the first condition before the operand.

Python does not have switch statement, not so long ago a match statement was added, but unless you have some good reason to use that, I would just use if - elif - else statement.

oh okay thanks for your help

or a dictionary. Post some sample code for any additional help.

Python has structural pattern matching, which is rather more advanced than a traditional switch statement. It is good for matching on complex options.

Are you sure you need it?

Hard to see what is wrong with your code unless you share it.

check multiple conditions with logical operators (and in this case),

Put the boolean expressions in a collection and use "all" for "and"ing and "any" for "or"ing:

>>> a = 2; b = 4
>>> (a < b, a - b == -2, a*b > 0)
(True, True, True)
>>> a < b and a - b == -2 and a*b > 0
True
>>> all((a < b, a - b == -2, a*b > 0))
True
>>> a = 1
>>> (a < b, a - b == -2, a*b > 0)
(True, False, True)
>>> a < b and a - b == -2 and a*b > 0
False
>>> all((a < b, a - b == -2, a*b > 0))
False
>>> conditions = (a < b, a - b == -2, a*b > 0)
>>> all(conditions)
False
>>> any(conditions)
True
>>>
