FPDF只写一行

Question

The variable "output" in the code below is a couple of paragraphs of text and I am trying to write it all to a pdf using FPDF. But, it writes to only one line. How do I get it to include line breaks. For example, the text has "\\n" in several locations of the text but its ignored. Thank you.

dummytext = "line 1" + "\n"
dummytext += "line 2" + "\n"
dummytext += "line 3"

pdf = FPDF()
pdf.add_page()
pdf.set_xy(0,0)
pdf.set_font('arial', 'B', 13.0)
pdf.cell(ln=0, h=5.0, align='L', w=0, txt=dummytext, border=0)
pdf.output('testpdf.pdf', 'F')

The variable dummytext shows up in the pdf as:

line 1 line 2 line 3

Using multi_cell will facilitate the new lines in FPDF output.

multi_cell : This method allows printing text with line breaks.

Details can be found in Documentation of multi_cell .

code.py :

from fpdf import FPDF
dummytext = "line 1" + "\n"
dummytext += "line 2" + "\n"
dummytext += "line 3"
pdf = FPDF()
pdf.add_page()
pdf.set_xy(0,0)
pdf.set_font('arial', 'B', 13.0)
pdf.multi_cell(0, 5, dummytext)
pdf.output('testpdf.pdf', 'F')

Output:
