from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Paragraph
from reportlab.lib.styles import getSampleStyleSheet

# 定义包含变量和其对应值的字典
variable_dict = {
    "name": "John Doe",
    "age": "30",
    "occupation": "Software Engineer"
}

# 创建PDF文档
doc = SimpleDocTemplate("output.pdf", pagesize=letter)
story = []

# 定义段落内的变量
paragraph_text = "My name is $name$. I am $age$ years old. My occupation is $occupation$."

# 替换段落中的变量
for key, value in variable_dict.items():
    paragraph_text = paragraph_text.replace(f"${key}$", value)

# 创建段落并添加到文档中
styles = getSampleStyleSheet()
paragraph = Paragraph(paragraph_text, styles["Normal"])
story.append(paragraph)

# 将story添加到文档中并保存为PDF文件
doc.build(story)
