**π‘ Problem Formulation:** The task is to write a Python program capable of taking a series of numbers and an exponent value, then computing and printing the power of each element raised to the given exponent. For example, given the series [2, 3, 4] and exponent 2, the desired output would be [4, 9, 16].

## Method 1: List Comprehension

This method uses Python’s list comprehension feature to create a new list where each element from the original series is raised to the power of the given exponent. List comprehension is a concise and readable way to transform one list into another.

Here’s an example:

series = [2, 3, 4] exponent = 2 powered_series = [x**exponent for x in series] print(powered_series)

Output: [4, 9, 16]

The `[x**exponent for x in series]`

line is the list comprehension, which iterates over each number in the series and raises it to the power of `exponent`

, resulting in a new list of powered values.

## Method 2: Using the map() function

The `map()`

function applies a given function to all items in an iterable and returns a map object. By passing a lambda function that calculates the power, we can elegantly apply this operation to the entire series.

Here’s an example:

series = [2, 3, 4] exponent = 2 powered_series = list(map(lambda x: x**exponent, series)) print(powered_series)

Output: [4, 9, 16]

The lambda function within the `map()`

call is an anonymous function that computes the power for each element, which is then converted back to a list for printing.

## Method 3: Using a for loop

A traditional for loop can be used to iterate through each element in the series and calculate its power individually. This method is straightforward and easy for beginners to understand.

Here’s an example:

series = [2, 3, 4] exponent = 2 powered_series = [] for x in series: powered_series.append(x**exponent) print(powered_series)

Output: [4, 9, 16]

The for loop traverses each element in the `series`

, then computes its power and appends the result to the `powered_series`

list, which is printed after the loop.

## Method 4: Using the pow() function

Alternatively, Python’s built-in `pow()`

function can be used to compute the power of each element. This function is built-in and is specifically designed for power calculations.

Here’s an example:

series = [2, 3, 4] exponent = 2 powered_series = [pow(x, exponent) for x in series] print(powered_series)

Output: [4, 9, 16]

Using `pow(x, exponent)`

inside a list comprehension offers both readability and efficiency by leveraging a dedicated power function.

## Bonus One-Liner Method 5: NumPy Library

For those working within a scientific computing context, NumPy provides a variety of fast array operations. Here’s a one-liner using NumPy to raise each element in an array to a power.

Here’s an example:

import numpy as np series = np.array([2, 3, 4]) exponent = 2 powered_series = np.power(series, exponent) print(powered_series)

Output: [4 9 16]

The `np.power(series, exponent)`

function raises each element in the ‘series’ array to the specified ‘exponent’, showcasing NumPy’s efficiency for numerical computations.

## Summary/Discussion

**Method 1: List Comprehension.**Provides concise syntax. Most Pythonic way with excellent readability. Potentially less clear for newcomers to the language.**Method 2: map() function.**Offers functional programming approach. Good for single-line operations but requires conversion to list for printing. Less readable than list comprehension.**Method 3: Using a for loop.**Great for beginners. Easy to understand. More verbose and potentially less efficient for larger series.**Method 4: pow() function.**Utilizes Python’s dedicated power function. Readable and precise. Mostly advantageous when needing to specify a modulo as the third argument to`pow()`

.**Method 5: NumPy Library.**Best for performance on large data sets. Requires an additional library. Non-intuitive for those outside scientific computing circles.
