Python嵌套字典列表中文件路径触发UnicodeEscape语法错误求助

错误原因 #

你写的路径里用了单个反斜杠\，在Python字符串中\是转义字符。比如\Uncommon里的\U会被识别为Unicode转义序列的开头（要求后面跟8位十六进制数），但你这里后面是字母，所以触发截断错误。

三种修复方案 #

• 方案1：用双反斜杠代替单个反斜杠
  把路径里的\换成\\，让Python把它当成普通的反斜杠字符：

  Bases = [
      {
          "BC0": ["Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_base.PNG", "Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_bonus1.PNG",
                  "Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_bonus2.PNG", "Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_accent.PNG",
                  "Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_shadows.PNG", "Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_eyesbeakfeet.PNG",
                  "Owl_project_pictures\\Common\\Great Grey Owl\\_greatgrey_lines.PNG"],
          "BC1": ["Owl_project_pictures\\Common\\Barn Owl\\_barn_base.PNG", "Owl_project_pictures\\Common\\Barn Owl\\_barn_bonus1.PNG",
                  "Owl_project_pictures\\Common\\Barn Owl\\_barn_bonus2.PNG", "Owl_project_pictures\\Common\\Barn Owl\\_barn_bonus2.PNG",
                  "Owl_project_pictures\\Common\\Barn Owl\\_barn_accent.PNG", "Owl_project_pictures\\Common\\Barn Owl\\_barn_shadows.PNG",
                  "Owl_project_pictures\\Common\\Barn Owl\\_barn_eyesbeakfeet.PNG", "Owl_project_pictures\\Common\\Barn Owl\\_barn_lines.PNG"],
          "BC2": ["Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_base.PNG","Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_bonus1.PNG",
                  "Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_bonus2.PNG", "Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_accent.PNG",
                  "Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_shadows.PNG", "Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_eyesbeakfeet.PNG",
                  "Owl_project_pictures\\Common\\Burrowing Owl\\_burrowing_lines.PNG"]
      },
      {
          "BU0": ["Owl_project_pictures\\Uncommon\\Crested Owl\\_crested_base.PNG", "Owl_project_pictures\\Uncommon\\Crested Owl\\_crested_bonus1.PNG"]
      }
  ]
  

• 方案2：使用原始字符串
  在字符串前面加r，告诉Python不要解析转义字符：

  Bases = [
      {
          "BC0": [r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_base.PNG", r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_bonus1.PNG",
                  r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_bonus2.PNG", r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_accent.PNG",
                  r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_shadows.PNG", r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_eyesbeakfeet.PNG",
                  r"Owl_project_pictures\Common\Great Grey Owl\_greatgrey_lines.PNG"],
          "BC1": [r"Owl_project_pictures\Common\Barn Owl\_barn_base.PNG", r"Owl_project_pictures\Common\Barn Owl\_barn_bonus1.PNG",
                  r"Owl_project_pictures\Common\Barn Owl\_barn_bonus2.PNG", r"Owl_project_pictures\Common\Barn Owl\_barn_bonus2.PNG",
                  r"Owl_project_pictures\Common\Barn Owl\_barn_accent.PNG", r"Owl_project_pictures\Common\Barn Owl\_barn_shadows.PNG",
                  r"Owl_project_pictures\Common\Barn Owl\_barn_eyesbeakfeet.PNG", r"Owl_project_pictures\Common\Barn Owl\_barn_lines.PNG"],
          "BC2": [r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_base.PNG",r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_bonus1.PNG",
                  r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_bonus2.PNG", r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_accent.PNG",
                  r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_shadows.PNG", r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_eyesbeakfeet.PNG",
                  r"Owl_project_pictures\Common\Burrowing Owl\_burrowing_lines.PNG"]
      },
      {
          "BU0": [r"Owl_project_pictures\Uncommon\Crested Owl\_crested_base.PNG", r"Owl_project_pictures\Uncommon\Crested Owl\_crested_bonus1.PNG"]
      }
  ]
  

• 方案3：用正斜杠代替反斜杠
  Python支持用正斜杠作为路径分隔符，直接替换所有\为/：

  Bases = [
      {
          "BC0": ["Owl_project_pictures/Common/Great Grey Owl/_greatgrey_base.PNG", "Owl_project_pictures/Common/Great Grey Owl/_greatgrey_bonus1.PNG",
                  "Owl_project_pictures/Common/Great Grey Owl/_greatgrey_bonus2.PNG", "Owl_project_pictures/Common/Great Grey Owl/_greatgrey_accent.PNG",
                  "Owl_project_pictures/Common/Great Grey Owl/_greatgrey_shadows.PNG", "Owl_project_pictures/Common/Great Grey Owl/_greatgrey_eyesbeakfeet.PNG",
                  "Owl_project_pictures/Common/Great Grey Owl/_greatgrey_lines.PNG"],
          "BC1": ["Owl_project_pictures/Common/Barn Owl/_barn_base.PNG", "Owl_project_pictures/Common/Barn Owl/_barn_bonus1.PNG",
                  "Owl_project_pictures/Common/Barn Owl/_barn_bonus2.PNG", "Owl_project_pictures/Common/Barn Owl/_barn_bonus2.PNG",
                  "Owl_project_pictures/Common/Barn Owl/_barn_accent.PNG", "Owl_project_pictures/Common/Barn Owl/_barn_shadows.PNG",
                  "Owl_project_pictures/Common/Barn Owl/_barn_eyesbeakfeet.PNG", "Owl_project_pictures/Common/Barn Owl/_barn_lines.PNG"],
          "BC2": ["Owl_project_pictures/Common/Burrowing Owl/_burrowing_base.PNG","Owl_project_pictures/Common/Burrowing Owl/_burrowing_bonus1.PNG",
                  "Owl_project_pictures/Common/Burrowing Owl/_burrowing_bonus2.PNG", "Owl_project_pictures/Common/Burrowing Owl/_burrowing_accent.PNG",
                  "Owl_project_pictures/Common/Burrowing Owl/_burrowing_shadows.PNG", "Owl_project_pictures/Common/Burrowing Owl/_burrowing_eyesbeakfeet.PNG",
                  "Owl_project_pictures/Common/Burrowing Owl/_burrowing_lines.PNG"]
      },
      {
          "BU0": ["Owl_project_pictures/Uncommon/Crested Owl/_crested_base.PNG", "Owl_project_pictures/Uncommon/Crested Owl/_crested_bonus1.PNG"]
      }
  ]
  

额外提醒 #

其实你前面的BC0、BC1、BC2路径也有同样的隐患，只是刚好没有触发转义错误（比如\Common的\C不是特殊转义序列），但最好统一修复，避免后续出问题。
