print this using python

I have tried

def print_pattern(rows):
    for i in range(rows):
        start_char = '1' if i % 2 == 0 else '0'   
        pattern = ''.join(start_char if j % 2 == 0 else ('0' if start_char == '1' else '1') for j in range(i + 1))
        print(pattern) 

number_of_rows = 4
print_pattern(number_of_rows)
