需要帮助将RLE转换为ASCII美工

Question

目标是将存储文本文件的RLE转换为在控制台中打印的ASCII Art。用户必须输入文本文件的名称。每次尝试更改或改进代码时，都会出现错误。

代码：

def convtoASCII():
    print("\nYou have chosen Convert to ASCII\n")
    name = input("\nWhat is the name of your RLE file?")
    try:
        lines = len(open(name).readlines(  ))
        for _ in range(lines):
            line = lines
        piece = [line[i:i+3] for i in range(0, len(line), 3)]
        for part in piece:
            length = int(part[0:2])
            character = part[2]
            print(length * character, end='')
    except:
        print("\nInvalid file name. Please try again\n")
        convtoASCII()

这是我收到的错误消息：

Traceback (most recent call last):
  File "C:\Users\ayaan\Documents\RLE to ASCII\Raw Code.py", line 100, in <module>
    welcome()
  File "C:\Users\ayaan\Documents\RLE to ASCII\Raw Code.py", line 8, in welcome
    menu()
  File "C:\Users\ayaan\Documents\RLE to ASCII\Raw Code.py", line 19, in menu
    convtoASCII()
  File "C:\Users\ayaan\Documents\RLE to ASCII\Raw Code.py", line 83, in convtoASCII
    piece = [line[i:i+3] for i in range(0, len(line), 3)]
TypeError: object of type 'int' has no len()

任何帮助将不胜感激

谢谢
