如何有效地将整数转换为字符串极坐标？

import math

def integer_to_polar_string(num):
    # Step 1: Convert integer to polar coordinates
    modulus = abs(num)
    angle = math.degrees(math.atan(num))

    # Step 2: Convert modulus and angle to string
    modulus_str = str(modulus)
    angle_str = str(angle)

    # Step 3: Concatenate modulus and angle strings
    polar_str = modulus_str + " " + angle_str

    return polar_str

# Example usage
integer = 10
polar_string = integer_to_polar_string(integer)
print(polar_string)
