Python-Nested if Statements

Python-Nested IF Statements

Python has nested if statements and this refers to the use of conditional if or else statements inside the existing if statement. Read this article to learn more about Python-nested If Statements.

Whereas, In some cases, we need nesting of if statements to make the entire program flow of code in a semantic order and make it easily readable.

Example of Python-Nested IF Statements

However, nested will be used to check for another condition after another condition has come true. Inside the nested if construct, it is possible to use the if …elif..else construct.

Syntax

The syntax of nested if…else…else construct will be provided below:

if expression1:
   statement(s)
   if expression2:
      statement(s)
   elif expression3:
      statement(s)3
   else
      statement(s)
elif expression4:
   statement(s)
else:
   statement(s)

Example

# Nested if...else...else construct example with number 5

# Set the number to 5
number = 5

# Checking conditions using nested if...else...else
if number > 0:
    print("The number is positive.")
elif number < 0:
    print("The number is negative.")
else:
    print("The number is zero.")

Output

The number is positive.

Conclusion

This article will allow the students to improve their skills and knowledge about the Python nested if statements. A nested if statement in programming allows for the evaluation of multiple conditions in a hierarchical manner.

Therefore, it provides a structured way to handle various scenarios by checking conditions sequentially. Each if statement is associated with a block of code, and the program executes the block corresponding to the first true condition encountered.
