Now In this tutorial, we will discuss Replacements for switch statements in Python? as we do not use The keyword Switch in Python instate of a switch we match the keyword in python so let’s all the changes that we face in the case of Python.
The switch is a statement in Java and C/C++ where we deal with either integers or characters to check whether the given input is a match with any of the possible cases where we already know the possible outcomes.
We only have to make the exact match and execute a set of codes on the match found.
int f(x): Switch(x): case 'a': return 1 case 'b': return 2 case _: return 0 # 0 is the default case if x is not found
The above code shows how a java code runs using a switch case. Here the value of x decides which case it is going to match and depends upon that it runs the code given after that until either it encounters a break or returns statement it keeps on executing all the statements after a certain match.
The case is the multiple statements that contain all the possible outcome as case 1, case, and so on, and where ever it is found to be a match, It starts executing all the statements after that and keep on executing until the break or return statement.
The match is the same as a switch in java, C/C++ where it deals with integers and characters to check and compare the value of a variable with all the possible pre-defined values which are already entered by the user in the program.
It also deals with some variables which have only integers of character types data types and compares it with already known values once it finds a match it starts printing all the values after that until it gets a break or return statements.
Let’s see the same example for the match also that we had taken for the switch
def f(x): match x: case 'a': return 1 case 'b': return 2 case _: return 0 # 0 is the default case if x is not found
Difference Between Switch And Match
The main difference between Switch and Match is the use of different languages. As discussed Switch is used in C/C++ and Java, etc whereas Match is used in Python, Pascal, etc.
