Is there a short-hand for nth root of x in Python?

There isn't a specific shorthand for nth root in Python, but you can use the power operator (**) along with fractional exponents to calculate nth roots.

Here's an example:

# Calculate the square root (n=2) of x x = 16 square_root = x ** (1/2) print(f"Square root of {x}: {square_root}") # Calculate the cube root (n=3) of x cube_root = x ** (1/3) print(f"Cube root of {x}: {cube_root}")

In the example above, (1/2) represents the square root, and (1/3) represents the cube root. You can replace these values with (1/n) to calculate the nth root.

If you frequently need to calculate nth roots, you might define a function to make it more readable:

def nth_root(x, n): return x ** (1/n) # Example usage x = 16 fourth_root = nth_root(x, 4) print(f"Fourth root of {x}: {fourth_root}")

This function takes x and n as parameters and calculates the nth root of x.
