使用Python将.py文件转换为PDF并实现语法高亮

from spire.doc import Document, FileFormat, BreakType, Color, LineSpacingRule, LineNumberingRestartMode

# 读取 Python 文件
with open("Python.py", "r", encoding="utf-8") as f:
    python_code = f.read()

# 创建文档对象
doc = Document()
section = doc.AddSection()
paragraph = section.AddParagraph()

# 逐行添加代码
for line_number, line in enumerate(python_code.split("\n")):
    tr = paragraph.AppendText(line)
    tr.CharacterFormat.FontName = "Courier New"  # 设置等宽字体
    tr.CharacterFormat.FontSize = 10.5
    if line_number < len(python_code.split("\n")) - 1:
        paragraph.AppendBreak(BreakType.LineBreak)

# 可选格式设置
paragraph.Format.BackColor = Color.get_WhiteSmoke()  # 背景色
paragraph.Format.LineSpacingRule = LineSpacingRule.Multiple
paragraph.Format.LineSpacing = 14.0

# 行号设置
section.PageSetup.LineNumberingStartValue = 1
section.PageSetup.LineNumberingStep = 1
section.PageSetup.LineNumberingRestartMode = LineNumberingRestartMode.RestartPage
section.PageSetup.LineNumberingDistanceFromText = 12.0

# 保存为 PDF
doc.SaveToFile("output/Python-PDF.pdf", FileFormat.PDF)

from spire.doc import Document, FileFormat
from pygments import highlight

from pygments.formatters import HtmlFormatter

# 保存带高亮的 PDF
