python - 在另一个脚本中调用一个 python 脚本

Question

我看到了几个与我的问题相关的问题，但无法得到答案。

在我的程序中，我有一个需要转换为 PDF 的 .txt 文件。我遇到了执行相同操作的脚本，https://code.activestate.com/recipes/189858-python-text-to-pdf-converter/

我已将其导入到我的程序中，但我不确定如何调用和传递我的 txt 文件以便将其转换为 PDF。

.txt 到 .pdf 转换器脚本名称是 txttopdf.py 我已将其导入为 import txttopdf 并且它存在于同一目录中

我程序的最后一部分试图将 .txt 转换为 .pdf，但它给我一个语法错误。下面是我的程序 导入sqlite3 导入平台 导入系统 导入操作系统 重新进口 导入时间 导入 smtplib 导入模仿类型 导入 txttopdf 从日期时间导入日期时间 从 email.mime.multipart 导入 MIMEMultipart 从电子邮件导入编码器 来自 email.message 导入消息

    from email.mime.text import MIMEText
    ipstr = "unknown"

最简单的方法是通过 subprocess.Popen :

示例:

import sys
from subprocess import Popen, PIPE,, STDOUT


PYTEXT2PDF = "/path/to/pytext2pdf"


def convert(filename):
    print("Converting {} to PDF".format(filename))

    p = Popen(
        [sys.executable, PYTEXT2PDF, filename],
        stdout=PIPE, stderr=STDOUT
    )

    stdout, _ = p.communicate()

    print(stdout)


convert("filename.txt")

从外观上看； pyText2Pdf将文本文件转换为 PDF 并将输出文件命名为与输入文件相同的“basenaem”，扩展名为 .pdf。
