The program stopped working. What is it?

[Bogopo]

Some time ago, the program was working - to remove the equations and words. She's not starting now.

def main():
    argument1 = [[1, 1, 1],
                 [1, 0, 0]]
    argument2 = [[0, 0, 0],
                 [1, 1, 1]]
    template = [argument1, argument2]
n = 1
for data in template:
    print_data(data)

def print_data(data):

for i in range(len(data)):

for j in range(len(data[i])):

print_images_foreach_delta(data, i, j)
def print_images_foreach_delta(data, i, j):

size = len(data[0])

for delta in range(1, size - (i + j)):

for image_index in range(len(data)):

print_image(data, image_index, i, j, delta)
def print_image(data, image_index, i, j, delta):

print('Изображение номер - ', image_index + 1, sep="")

for func in range(len(data)):

print(f'{int(func == image_index)} = R{func + 1} = {data[image_index][i]} * A1({func + 1}) + {data[image_index][i + j + delta]} * A2({func + 1})')
if name == "main":

main()
