Python String Wrap

Question

我想在此脚本中将字符串包装为30,700。这样做的最佳方式是什么，我尝试过使用textWrap，但似乎没有用。这是我的代码：

from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

canvas = canvas.Canvas("Forensic Report.pdf", pagesize=letter)
canvas.setLineWidth(.3)
canvas.setFont('Helvetica', 12)

canvas.drawString(30,750,'LYIT MOBILE FORENSICS DIVISION')
canvas.drawString(500,750,"Date: 12/02/2018")
canvas.line(500,747,595,747)

canvas.drawString(500,725,'Case Number:')
canvas.drawString(580,725,"10")
canvas.line(500,723,595,723)


canvas.drawString(30, 700, 'This forensic report has been compiled by the forensic examiner in conclusion to the investigation into the RTA case which occured on 23/01/2018')


canvas.save()
print("Forensic Report Generated")

Answer 1

也许您想使用drawText？ 这样做，您的代码将是

from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

canvas = canvas.Canvas("Forensic Report.pdf", pagesize=letter)
canvas.setLineWidth(.3)
canvas.setFont('Helvetica', 12)
canvas.drawString(30,750,'LYIT MOBILE FORENSICS DIVISION')
canvas.drawString(500,750,"Date: 12/02/2018")
canvas.line(500,747,595,747)

canvas.drawString(500,725,'Case Number:')
canvas.drawString(580,725,"10")
canvas.line(500,723,595,723)

line1 = 'This forensic report has been compiled by the forensic'
line2 = 'examiner in conclusion to the investigation into the RTA'
line3 = 'case which occured on 23/01/2018'
textobject = canvas.beginText(30, 700)
lines = [line1, line2, line3]
for line in lines:
    textobject.textLine(line)

canvas.drawText(textobject)
canvas.save()

这也是建议here的解决方案。不幸的是，我不认为它是新行自动文本换行的有效解决方案，即你应该自己管理如何拆分字符串。
