Correct option is B
The expression
power(X, Y) will not return the result of X raised to the power Y. There is no built-in power() function in Python. Instead, the correct functions or operators are pow(X, Y), math.pow(X, Y), and X**Y, all of which will calculate X raised to the power Y.
Important Key Points:
1.
pow(X, Y): This is a built-in Python function that returns X raised to the power Y.
2.
math.pow(X, Y): This is a function from the math module that also returns X raised to the power Y as a floating-point number.
3.
X**Y: This is the exponentiation operator in Python, which directly calculates X raised to the power Y.
4.
power(X, Y): This is not a valid Python function. It will result in an error unless you define a custom function named power.
Knowledge Booster:
·
Option (a):
pow(X, Y) is a valid built-in Python function that computes X raised to the power Y.
·
Option (c):
math.pow(X, Y) is a function from the math module in Python, which calculates X raised to the power Y and returns the result as a float.
·
Option (d):
X**Y is the correct exponentiation operator in Python and is commonly used to compute powers.
