PythonServer Side ProgrammingProgramming Suppose we have two inputs x and n. x is a number in range -100.0 to 100.0, and n is a 32-bit signed integer. We have to find x to the power n without using library functions. So if the given inputs are x = 12.1, n = -2, then output...
Python code to find power of a number using loopnum = int(input("Enter the number of which you have to find power: ")) pw = int(input("Enter the power: ")) kj = 1 for n in range(pw): kj = kj*num print(kj) Output

This formula gets the sentiment score from the API, and stores it in a collection: The formula calls the DetectSentiment function with the three parameters exposed by the custom connector: id, language, and text. We specify values for the first two right in the formula, and get the value ...
To calculate the power of a number, the “math.pow()” function is utilized in the Python program. It returns a value of base raised to a power of exponent. The “math.pow()” function takes two parameter values, base and exponent. The function returns “ValueErrors” when the base nu...
