简单python脚本，将jupter notebook的ipynb文件转为pdf（包含中文）

Posted 2020-08-28

直接执行的python代码ipynb2pdf.py

# coding:utf-8
import sys
import os
import re
import shutil
notebook = sys.argv[1]
texFile = notebook.replace(‘.ipynb‘,‘.tex‘)
# 1.convert .ipynb to latex file .tex
# 将ipynb文件转为tex文件
print ‘1. convert ‘ + notebook + ‘ to ‘ + texFile  
print ‘------ \n‘
os.system(r‘jupyter nbconvert --to latex ‘ + notebook)
print ‘convert over‘
# 2. add Chinese support by adding the string below
# 加入引用的包使支持中文（直接转换中文会丢失）
# \usepackage{fontspec, xunicode, xltxtra}
# \setmainfont{Microsoft YaHei} 
# \usepackage{ctex}
print ‘2. add Chinese support to .tex file‘ 
print ‘------‘
file = open(texFile,‘r‘)
str_file = file.read()
strinfo = re.compile(‘(documentclass[\d\D]+\{article\})‘)  #查找的字符line0
m=re.findall(strinfo,str_file)
if len(m) == 0:
    print r‘can not find documentclass[**pt]{article}‘
    sys.exit(1)
str_file = strinfo.sub(‘\\1 \n \\usepackage{fontspec, xunicode, xltxtra} \n \\setmainfont{Microsoft YaHei} \r \\usepackage{ctex}‘,str_file)  #  替换的字符line1
file.close()
file = open(texFile,‘w‘)
file.write(str_file)
file.close()
print ‘add Chinese support successed‘
# 3. convert .tex to .pdf by xelatex
# 使用xelatex命令编译.tex文件得到pdf
print  ‘3. convert tex to pdf‘
print ‘------‘
os.system(‘xelatex ‘ + texFile)
print  ‘convert pdf successed‘
# 4. delete the auxiliary files
# 清理生成的中间文件
# change there if latex file is needed
print ‘4. delete auxiliary files‘
print ‘------‘
os.remove(notebook.replace(‘.ipynb‘,‘.aux‘))
os.remove(notebook.replace(‘.ipynb‘,‘.log‘))
os.remove(notebook.replace(‘.ipynb‘,‘.out‘))
# change there if latex file is needed
os.remove(notebook.replace(‘.ipynb‘,‘.tex‘))
if os.path.isdir(notebook.replace(‘.ipynb‘,‘_files‘)):
    shutil.rmtree(notebook.replace(‘.ipynb‘,‘_files‘))
print ‘delete auxiliary files successed‘

调用方式

1. 在当前目录中打开命令行(目录中要有ipynb2pdf.py 与 .ipynb文件）
2. 输入命令
   python ipynb2pdf.py yourFilename.ipynb

打包为exe（可以忽略）

使用pyinstaller打包为exe，作为命令行命令
pyinstaller -F ipynb2pdf.py
生成的exe放入系统path目录的文件夹下即可直接通过命令的形式处理

调用时在.ipynb所在的文件夹下打开命令行，输入命令
ipynb2pdf yourFilename.ipynb
