Python 如何使用文本数据创建自定义 PDF

Use multi_cell() method instead of text() method.
multi_cell or cell are recommended by the text() method documentation:

From text() method documentation:
text() method prints a character string. The origin is on the left of the first character, on the baseline. This method allows placing a string precisely on the page, but it is usually easier to use cell, multi_cell or write, which are the standard methods to print text.

为了测试您的程序，我创建了一个名为file.txt的文本文件，其中包含示例文本:

Hello World. This is test text.
ASDFASDFAAAAAAAAAAAAAAAAAAAAAAA
Hello World. This is test text.
ASDFASDFAAAAAAAAAAAAAAAAAAAAAAA
Hello World. This is test text.
ASDFASDFAAAAAAAAAAAAAAAAAAAAAAA

如果我将您的代码更改为使用multi_cell()，并从文本文件file.txt中读取PDF文件的文本消息，则您的程序将变为:

from fpdf import FPDF
import webbrowser

fileNameBase = "question_so"

'''+++++++++++++++++++++++++++++++++++++++++++++++++++
Reads and returns the text contained into the file.txt 
+++++++++++++++++++++++++++++++++++++++++++++++++++'''
def get_file_content():
    text = ""
    with open('file.txt') as f:
        for line in f:
            text += line
    return text

def main():

    pdf = FPDF()

    pdf.add_page()
    pdf.set_font('Arial', 'B', 14)
    # I have comment your call to text() method
    #pdf.text(0, 0 , text)
    # read the content of the file
    text = get_file_content()
    pdf.multi_cell(w=210, h=6, txt=text, border=0, align='L', fill=False)

    pdf.output(fileNameBase + ".pdf", "F")
    webbrowser.open_new('question_so.pdf')

main()

通过执行函数main()，我得到一个名为question_so.pdf的PDF文件，其内容如下:
