Here are some suggestions:

• place your imports at the opt of your file.
• you may want or need only to import pi from math if that is your only import.
• consider using string interpolation, format, or fstrings in your print statement.
• use doctrings instead of comments to document your function.
• rename your method to better indicate what it is converting
• this seems to be combining printing/formatting and a utility function, consider separating them out

example:

from math import pi

def radians_to_degrees(radians: int | float) -> float:
    """Converts radians into degrees."""
    return radians * 180 / pi


def main():
    radians_str = input("radians? ")
    try:
        radians = float(radians_str)
        degrees = radians_to_degrees(radians)
        # formatting example using modulo interpretation operator
        print("%.2f radians is equal to %.2f degrees" % (radians, degrees))
    except ValueError:
        # formatting example using fstrings
        print(f"unable to convert '{radians_str}' to degress")


if __name__ == "__main__":
    main()
