Revolutionizing Python Programming
Introduction to Revolutionizing Python Programming
Python is one of the most popular programming languages in the world. It is known for its simplicity, ease of use, and versatility. One of the newest features added to revolutionizing Python programming is the switch case statement. This feature was added in Python 3.10 and has been long-awaited by developers who have been using other programming languages that already had this feature.

Switch Case Statement:
A switch case statement is a control structure that allows a program to evaluate an expression and execute a different set of statements depending on the value of the expression. The switch case statement is similar to an if-else statement, but it is more concise and easier to read. looking to learn the most popular programming language, Python, in Pune? Look no further!

The switch case statement in Python 3.10 works as follows:
match expression:
case value1:
# code to be executed when value1 is matched
case value2:
# code to be executed when value2 is matched
…
case valueN:
# code to be executed when valueN is matched
case _:
# code to be executed when none of the values match
As you can see, the switch case statement in Python 3.10 uses the “match” keyword followed by an expression to be evaluated. Then, the “case” keyword is used to specify the different possible values that the expression can take. Finally, the “case _” specifies the default case when none of the other cases match.
Example of Revolutionizing Python Programming 1:
Let’s take a look at an example of how to use the switch case statement in Python 3.10. Suppose we want to write a program that takes a number as input and prints out whether the number is positive, negative, or zero. Here is how we can do this using the switch case statement:
def check_number(num):
match num:
case num > 0:
print(“Positive number”)
case num < 0:
print(“Negative number”)
case _:
print(“Zero”)
In this example, we define a function “check_number” that takes a number “num” as input. Then, we use the switch case statement to check the value of “num”. If “num” is greater than 0, we print “Positive number”. If “num” is less than 0, we print “Negative number”. Otherwise, we print “Zero”.

Example 2:
Let’s take a look at another example of how to use the switch case statement in Python 3.10. Suppose we want to write a program that takes a string as input and prints out whether the string is “red”, “green”, “blue”, or “unknown”. Here is how we can do this using the switch case statement:
def check_color(color):
match color:
case “red”:
print(“Red”)
case “green”:
print(“Green”)
case “blue”:
print(“Blue”)
case _:
print(“Unknown”)
In this example, we define a function “check_color” that takes a string “color” as input. Then, we use the switch case statement to check the value of “color”. If “color” is “red”, we print “Red”. If “color” is “green”, we print “Green”. If “color” is “blue”, we print “Blue”. Otherwise, we print “Unknown”.

Conclusion:
The switch case statement is a useful feature that has been long-awaited by developers who have been using other programming languages. It is more concise and easier to read than an if-else statement, and it can make code more efficient. In this blog post, we have seen how to use the switch case statement in Python 3.10 with two examples.
