python导出pdf在pdf中生成六宫格数独题并画出相应方格

要实现这个功能，我们需要使用Python中的一些库，包括reportlab和Pillow。reportlab用于创建PDF文件，Pillow用于生成图像。

首先，我们需要创建一个PDF文档，并在其中添加一个标题和一个六宫格数独题：

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
from reportlab.lib.units import inch
from reportlab.lib import colors

# 创建PDF文档
c = canvas.Canvas("sudoku.pdf", pagesize=letter)

# 添加标题
c.setFont("Helvetica-Bold", 16)
c.drawString(2.5*inch, 10.5*inch, "Sudoku Puzzle")

# 添加数独题
c.setFont("Helvetica", 12)
c.drawString(2.5*inch, 9.5*inch, "6 8 . . . . . . .")
c.drawString(2.5*inch, 9*inch, ". 4 . . . . . 5 .")
c.drawString(2.5*inch, 8.5*inch, ". 6 5 . . 1 . . .")
c.drawString(2.5*inch, 8*inch, ". . . 3 . . . 1 7")
c.drawString(2.5*inch, 7.5*inch, "8 . . . 5 . . . 4")
c.drawString(2.5*inch, 7*inch, "5 9 . . . 7 . 3 .")
c.drawString(2.5*inch, 6.5*inch, ". . . 1 . . 7 2 .")
c.drawString(2.5*inch, 6*inch, ". 1 . . . . . 6 .")
c.drawString(2.5*inch, 5.5*inch, ". . . . . . . 9 3")

# 保存PDF文档
c.showPage()
c.save()

接下来，我们需要画出相应的方格。我们可以使用Pillow库中的ImageDraw模块来画出方格。我们首先需要创建一个空的图像，然后在其中画出方格和数字：

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
from reportlab.lib.units import inch
from reportlab.lib import colors
from PIL import Image, ImageDraw, ImageFont

# 创建PDF文档
c = canvas.Canvas("sudoku.pdf", pagesize=letter)

# 添加标题
c.setFont("Helvetica-Bold", 16)
c.drawString(2.5*inch, 10.5*inch, "Sudoku Puzzle")

# 创建空图像
img = Image.new("RGB", (400, 400), color="white")
draw = ImageDraw.Draw(img)

# 画出方格
for i in range(10):
    if i % 3 == 0:
        line_width = 3
    else:
        line_width = 1
    draw.line((i*40, 0, i*40, 400), fill="black", width=line_width)
    draw.line((0, i*40, 400, i*40), fill="black", width=line_width)

# 画出数字
font = ImageFont.truetype("arial.ttf", size=20)
for i in range(9):
    for j in range(9):
        if puzzle[i][j] != ".":
            draw.text((j*40+15, i*40+10), puzzle[i][j], font=font, fill="black")

# 将图像保存为PNG文件
img.save("sudoku.png")

# 将PNG文件添加到PDF文档中
c.drawImage("sudoku.png", 2.5*inch, 5*inch, width=3*inch, height=3*inch)

# 保存PDF文档
c.showPage()
c.save()

注意，上面的代码中，我们使用了一个名为puzzle的变量来存储数独题的内容。你需要将这个变量替换为你自己的数独题。

完整的代码如下：

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
from reportlab.lib.units import inch
from reportlab.lib import colors
from PIL import Image, ImageDraw, ImageFont

# 数独题
puzzle = [
    ["6", "8", ".", ".", ".", ".", ".", ".", "."],
    [".", "4", ".", ".", ".", ".", ".", "5", "."],
    [".", "6", "5", ".", ".", "1", ".", ".", "."],
    [".", ".", ".", "3", ".", ".", ".", "1", "7"],
    ["8", ".", ".", ".", "5", ".", ".", ".", "4"],
    ["5", "9", ".", ".", ".", "7", ".", "3", "."],
    [".", ".", ".", "1", ".", ".", "7", "2", "."],
    [".", "1", ".", ".", ".", ".", ".", "6", "."],
    [".", ".", ".", ".", ".", ".", ".", "9", "3"]
]

# 创建PDF文档
c = canvas.Canvas("sudoku.pdf", pagesize=letter)

# 添加标题
c.setFont("Helvetica-Bold", 16)
c.drawString(2.5*inch, 10.5*inch, "Sudoku Puzzle")

# 创建空图像
img = Image.new("RGB", (400, 400), color="white")
draw = ImageDraw.Draw(img)

# 画出方格
for i in range(10):
    if i % 3 == 0:
        line_width = 3
    else:
        line_width = 1
    draw.line((i*40, 0, i*40, 400), fill="black", width=line_width)
    draw.line((0, i*40, 400, i*40), fill="black", width=line_width)

# 画出数字
font = ImageFont.truetype("arial.ttf", size=20)
for i in range(9):
    for j in range(9):
        if puzzle[i][j] != ".":
            draw.text((j*40+15, i*40+10), puzzle[i][j], font=font, fill="black")

# 将图像保存为PNG文件
img.save("sudoku.png")

# 将PNG文件添加到PDF文档中
c.drawImage("sudoku.png", 2.5*inch, 5*inch, width=3*inch, height=3*inch)

# 保存PDF文档
c.showPage()
c.save()
