PPM image to ASCII art in Python

这是更新后的代码。我只需要它在同一行打印字符并在结尾处打破

import sys

def main(filename):
  image = open(filename)
  #reads through the first three lines
  color = image.readline().splitlines()
  size_width, size_height = image.readline().split()
  max_color = image.readline().splitlines()

  #reads the body of the file
  pixels = image.read().split()
  red = 0
  green = 0
  blue = 0
  r_g_b_value = []
  #pulls out the values of each tuple and coverts it to its grayscale value 
  for i in pixels:
    if i !=  "\n" or " ":
        if len(i) == 3:
            red = int(i[0]) * .3
            green = int(i[1]) * .59
            blue = int(i[2]) * .11
        elif len(i) == 2:
            red == int(i[0])
            green == int(i[1])
            blue == 0
        elif len(i) == 1:
            red == int(i[0])
            green == 0
            blue == 0

        r_g_b_value = [red + green + blue]
        grayscale = []
        character = []

            for j in r_g_b_value:
            if int(j) <= .2:
                character = "M"
            elif int(j) > .2 and int(j) <= .4:
                character = "#"
            elif int(j) > .4 and int(j) <= .6:
                character = "A"
            elif int(j) > .6 and int(j) <= .8:
                character = "@"
            elif int(j) > .8 and int(j) <= 1:
                character = "$"
            elif int(j) > 1 and int(j) <= 1.2:
                character = "0"
            elif int(j) > 1.2 and int(j) <= 1.4:
                character = "e"
            elif int(j) > 1.4 and int(j) <= 1.6:
                character = "a"
            elif int(j) > 1.8 and int(j) <= 2:
                character = "o"
            elif int(j) > 2 and int(j) <= 2.2:
                character = "="
            elif int(j) > 2.25 and int(j) <= 2.5:
                character = "+"
            elif int(j) > 2.5 and int(j) <= 2.75:
                character = ";"
            elif int(j) > 2.75 and int(j) <= 3:
                character = ":"
            elif int(j) > 3 and int(j) <= 3.4:
                character = ","
            elif int(j) > 3.4 and int(j) <= 3.9:
                character = "."
            else:
                character = " "

                                                                                                       character += character
            grayscale = [character]
            print(grayscale)

Answer 1

我猜这个错误源于：

        for j in len(r_g_b_value):

（len返回一个int）。

你可能想说

        for j in r_g_b_value
