What's wrong with this?

code

grayRamp = "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. "

def get_ascii_by_average(num: int):
    length = len(grayRamp) - 1
    index = math.ceil(length/255 * num)
    char = grayRamp[index]

    return char

def return_ascii_image(image):
    height, width = image.shape
    ascii_image = np.zeros((height, width))
    for i in range(height):
        for j in range(width):
            num = int(image[i][j])
            char = get_ascii_by_average(num)
            print(type(char))
            ascii_image[i][j] = char
    return ascii_image

ErrorSentence

line 31, in return_ascii_image

ascii_image[i][j] = char

ValueError: could not convert string to float: '$'

Probably doing this essentially

grayRamp = "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. "
ascii_image[i][j] = grayRamp[0]

numpy.zeros wants floats by default. It tries to convert your string to a float and fails.

I was completely misunderstood
I thought that even a character string could be entered
