Python: 在用于 LaTeX pdf 生成的字符串中插入变量

Question

你好，我是 Python 的新手，我想自动生成一些 latex pdf 报告。所以我想制作一个函数，将 x 个字符串变量作为输入并将它们插入到预定义的乳胶文本中，这样它就可以编译为报告 pdf。我真的希望有人能帮我解决这个问题。我试过如下所示，这显然不起作用：

def insertVar(site, turbine, country):
 site = str(site)
 turbine = str(turbine)
 country = str(country)

 report = r'''On %(site)s there are 300 %(turbine)s wind turbines, these lies in %(country)s'''

 with open('report.tex','w') as f:
  f.write(report)


 cmd = ['pdflatex', '-interaction', 'nonstopmode', 'report.tex']
 proc = subprocess.Popen(cmd, stdout=PIPE, stderr=PIPE)
 proc.communicate()

 retcode = proc.returncode
 if not retcode == 0:
    os.unlink('report.pdf')
    raise ValueError('Error {} executing command: {}'.format(retcode, ' '.join(cmd))) 

 os.unlink('report.tex')
 os.unlink('report.log')

insertVar('atsumi', 'ge', 'japan')

所以我希望 PDF 的输出为： "On atsumi there are 300 ge wind turbines, these lies in japan"

Answer 1

这是一个开始：

report = r'''On %(site)s there are 300 %(turbine)s wind turbines, these lies in %(country)s'''

with open('report.tex','w') as f:
   f.write(report)

应该是：

report = r'''On {a}s there are 300 {b}s wind turbines, these lies in {c}s'''.format(a=site, b=turbine, c=country)

with open('report.txt','w') as f:
       f.write(report)

Answer 2

尝试使用 str.format():

report = "On {} there are 300 {} wind turbines, these lies in {}".format(site, turbine, country)

如果您愿意，可以使用 % 代替，但请注意，这是旧样式：

report = "On %s there are 300 %s wind turbines, these lies in %s" % (site, turbine, country)

注意：我认为您没有必要使用原始字符串。
