title: Unknown Call to imported function (python)
body: <p>I have a simple python script to convert files to PDF. It has another function I made to merge them to one PDF file imported at the top. However, every time I run the convert script it runs the merge script as well even when I don't call the F_merge. The convert script is below. Why/where is it calling F_Merge?</p>
  
  <pre><code># Converts files  to PDF
  
  from PIL import Image
  import os,glob2,re
  from PDF_Merge_Script import F_Merge
  
  def Converter(filename):
      im = Image.open(filename)
      if im.mode == "RGBA":
          im = im.convert("RGB")
      if filename[-4:-1] == "jpe":
          new_filename = filename[:-4]+'pdf'
          if not os.path.exists(new_filename):
          im.save(new_filename,"PDF",resolution=100.0)
  else:
      new_filename = filename[:-3]+'pdf'
      if not os.path.exists(new_filename):
          im.save(new_filename,"PDF",resolution=100.0)
  
  PNG_files = glob2.glob("*.PNG")
  JPEG_files = glob2.glob("*.jpeg")
  JPG_files = glob2.glob("*.JPG")
  Txt_files = glob2.glob("*.txt")
  
  print(Txt_files)
  print(PNG_files)
  print(JPEG_files)
  print(JPG_files)

  <p>This is my output. No error. The printed statement is from a conditional in my merge function.</p>
  
  <p>Intially, No .pdf files in current directory or only one .pdf exists in directory</p>
  
  <p>['file1.txt']</p>
  
  <p>[]</p>
  
  <p>[]</p>
  
  <p>[]</p>
  
  <p>Here is the Merge Script</p>
  
  <pre><code>#Merges all .pdf files in the current directory where this scipt is saved
  
   from PyPDF2 import PdfFileMerger
   import os,glob2,re
  
   def  F_Merge(path):

    if len(pdf_files) &lt;= 1:
      print("Intially, No .pdf files in current directory or only one .pdf 
      exists in directory")
   else:
      merger = PdfFileMerger()
      for files in pdf_files:
          merger.append(path+files)

          merger.write(path+'merged.pdf')
      merger.close()

  path = re.sub(r'\\',r'/',os.getcwd()[2:])+'/'
  F_Merge(path)
