Assertion (A): The conditional flow of control is implemented using if statement.
Reasoning (R): A statement or statements (block of code) are indented (usually 4 spaces) inside the if statement and are executed only if the condition evaluates to true, otherwise they are ignored.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true and R is the correct explanation of A.
Explanation
The if statement in Python allows conditional flow of control. It evaluates a condition and executes one or more statements based on whether the condition is true or false. If the condition evaluates to true, the statement block following the if statement (indented code) gets executed, otherwise, if the condition is false, that block is skipped, and the program continues with the next statement after the if block.
Related Questions
if statement comes in which category of statements?
- Sequential statements
- Conditional statements.
- Iterative statements
- Loop statement
Assertion (A): When a set of statements is indented under the same block, starting from the same indentation, it is said to be a compound statement.
Reasoning (R): Compound Statement begins with a header ending with a colon (:) sign and the statements under the same indentation are marked as a block.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Assertion (A): In an if-else statement, the if block checks the true part whereas else checks for the false part.
Reasoning (R): In a conditional construct, else block is mandatory.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Assertion (A): When a Python code is unable to accept an input, it results in runtime error.
Reasoning (R): Runtime error arises due to incorrect statement that results in no output.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
