Python Program to Calculate Polynomial Derivative Using Enumerate

# Example 1
f = [4, 5, 0, 2]
dfdx = [i*f[i] for i in range(1, len(f))]
print(dfdx)  # Output: [5, 0, 6]

# Example 2
f = [10, 1, 1, 1, 1, 1]
dfdx = [i*f[i] for i in range(1, len(f))]
print(dfdx)  # Output: [1, 2, 3, 4, 5]

This code snippet efficiently calculates the derivative of a polynomial function represented as a list using Python's list comprehension and the enumerate function. Here's how it works:

• Polynomial Representation: The polynomial coefficients are stored in a list, f, where the index corresponds to the power of the variable.
• Derivative Calculation: The list comprehension [i*f[i] for i in range(1, len(f))] iterates through the elements of f (starting from index 1 to exclude the constant term) and multiplies each coefficient by its corresponding power (index). The result is stored in the list dfdx.
• Output: The program prints the derivative list dfdx.

This code provides a concise and efficient way to calculate the derivative of a polynomial function in Python, leveraging the power of list comprehension and the enumerate function.
