def print_in_xy_with_clean(self, x, y, char, color):
print("%c[%d;%df" % (0x1B, x, y), self.styles[color] + char + self.styles["ENDC"], end='')

Answer 1

As far as I see, both functions print a char or string (parameter "char") on a console which accepts ANSI escape sequences.

In fact the "char" is preceded by a positioning sequence "ESC [ x;y f", where x and y is the desired position, and included between two other sequences to set and reset its color.

The second function prepend a space to the coloured "char": this is the effect of printing comma-separated stuff.

Obviously you need ANSI support for this to work.
