Conditionalstatement
- 2. In programming and scripting languages, conditional statements or conditional constructs are used to perform different computations or actions depending on whether a condition evaluates to true or false.
- 3. Types of Conditional Statement if Statement elif Statement Nested If else Statement
- 4. Python if statement is one of the most commonly used conditional statements in programming languages. It decides whether certain statements need to be executed or not. It checks for a given condition, if the condition is true, then the set of code present inside the ” if ” block will be executed otherwise not. The if condition evaluates a Boolean expression and executes the block of code only when the Boolean expression becomes TRUE.
- 5. Syntax If ( EXPRESSION == TRUE ): Block of code else: Block of code Example num = 2 if (num < 10): print(“Num is smaller than 10”) print(“Yes, this condition is true ”)
- 7. “elif” statement is used to check multiple conditions only if the given condition is false. It’s similar to an “if-else” statement and the only difference is that in “else” we will not check the condition but in “elif” we will check the condition. “elif” statements are similar to “if-else” statements but “elif” statements evaluate multiple conditions. if (condition): #Set of statement to execute if condition is true elif (condition): #Set of statements to be executed when if condition is false and elif condition is true else: #Set of statement to be executed when both if and elif conditions are false Syntax:
- 8. num = 10 if (num == 0): print(“Number is Zero”) elif (num > 5): print(“Number is greater than 5”) else: print(“Number is smaller than 5”) Example Output Number is greater than 5
- 10. Nested “if-else” statements mean that an “if” statement or “if-else” statement is present inside another if or if-else block. Python provides this feature as well, this in turn will help us to check multiple conditions in a given program. Syntax: if (condition): #Set of statement to execute if condition is true elif (condition): #Set of statements to be executed when if condition is false and elif condition is true else: #Set of statement to be executed when both if and elif conditions are false
