在reportlab python中将文本靠右对齐

from reportlab.lib.styles import getSampleStyleSheet
from reportlab.platypus import Paragraph
from reportlab.lib.enums import TA_RIGHT

styles = getSampleStyleSheet()

right_aligned_style = styles["Normal"]
right_aligned_style.alignment = TA_RIGHT

text = "要靠右对齐的文本"
paragraph = Paragraph(text, right_aligned_style)

# 假设已经创建了PDF文档对象doc
doc.add(paragraph)
