Python- Decision Making

Python- Decision Making

The decisions in the program will take place when the program requires a conditional choice to run the code block. Read this article to learn more about Python -Decision Making.

Moreover, it denotes conditions that can run a program to specify those actions. Multiple expressions will be checked if the result is either True or False.

What is Python Decision-making?

The Python’s decision will be done through the keyword such as if..elif..else. Whereas, the keyword needs a boolean expression that will be followed by the colon ”:” symbol. The colon symbol will begin with an indented block.

Hence, these statements with the same level of indentation will be run only if the boolean expression in the if statement will come as True. Thus, if the expression is not either True or False, then the interpreter will bypass the indented block and will start to run the statements at an indentation level.

However, the decision structure will run multiple expressions, and that will give the result either as True or False. It is also necessary to determine which action to look forward to and which statement to run, to execute if the outcome is either True or False.

So, the programming language has non-zero and non-null values as True. In contrast, if the value is zero or null, then the result will be a false value.

The table below consists of different types of decision-making statements.

Sr.No.	Statement & Description
1	if statements  if statement has a boolean expression, that is followed by one or more statements.
2	nested if statements you can use one if or else if statement inside another if or else if statement(s).
3	if…. else statements An if statement will be followed by the optional else statement and will be run only when the boolean expression is False

What is Single Statement Suites?

The suite of an if clause consists of a single line, then it is possible to go to the same line as the header statement.

Examples of a one-line if clause are provided below:

x = 5
result = "Even" if x % 2 == 0 else "Odd"
print(result)

Output

odd

Conclusion

In Python, decision-making is achieved through structures like if, elif (else if), and else. These structures allow you to control the flow of your program based on conditions. With simple and intuitive syntax, Python’s decision-making features empower programmers to express logic clearly and concisely.
