TypeError:只能将tuple（而不是“int”）连接到tuple以及如何修复i

Question

每次使用Pygame运行Python编写的游戏时，我都会收到这个错误消息。错误消息是：

Traceback (most recent call last):
  File "/home/pi/Memory Puzzle_20171029.py", line 248, in <module>
    main()
  File "/home/pi/Memory Puzzle_20171029.py", line 58, in main
    startGameAnimation(mainBoard)
  File "/home/pi/Memory Puzzle_20171029.py", line 226, in startGameAnimation
    revealBoxesAnimation(board, boxGroups)
  File "/home/pi/Memory Puzzle_20171029.py", line 192, in revealBoxesAnimation
    drawBoxCovers(board, boxesToReveal, coverage)
  File "/home/pi/Memory Puzzle_20171029.py", line 182, in drawBoxCovers
    left, top = leftTopCoordsOfBox(box[0], box[1])
  File "/home/pi/Memory Puzzle_20171029.py", line 144, in leftTopCoordsOfBox
    left = boxx*(BOXSIZE + GAPSIZE) + XMARGIN
TypeError: can only concatenate tuple (not "int") to tuple

请帮忙，我是编程初学者，不知道Python中的所有错误。如果你能提供你的知识并帮助我解决这个问题，我将不胜感激 谢谢！！！

Answer 1

您正在尝试将元组添加/连接到整数。在

left = boxx*(BOXSIZE + GAPSIZE) + XMARGIN

如果您想将XMARGIN添加到元组boxx*(BOXSIZE + GAPSIZE)中的两个元素，那么可以这样做boxx*(BOXSIZE + GAPSIZE) + (XMARGIN, XMARGIN)
