Question

Identify the invalid Python statement out of the following options:

• A. print("A", 10, end="*")
• B. print("A", sep="*", 10)
• C. print("A", 10, sep="*")
• D. print("A"*10)

Hint:

In Python function calls,
positional arguments must always come before keyword arguments.
Mixing the order causes a syntax error.

Answer 1

The Correct Option is B

The print() function in Python outputs objects to standard output.
Its syntax supports multiple positional arguments before keyword arguments.
Key keyword arguments are sep (separator) and end (line ending).
Option (A) is valid: it prints `"A"` and `10` with end="*" modifying the line termination.
Option (C) is valid: it prints `"A"` and `10` with sep="*" inserted between them.
Option (D) is valid: `"A"*10` results in `"AAAAAAAAAA"`, which is permissible.
Option (B) is invalid because it places a positional argument after a keyword argument.
In Python, positional arguments must precede keyword arguments; any positional argument following a keyword argument will trigger a SyntaxError.
Consequently, option (B) is the invalid statement.
