pypdf用于pdfs列表

我已经让pypdf对单个pdf文件工作得很好,但我似乎无法让它适用于文件的lits,或者用于多个pdf的for循环,而不会失败,因为字符串不是调用。我可以将任何想法用作解决方法吗?

def getPDFContent(path):
    content = ""
    # Load PDF into pyPDF
    pdf = pyPdf.PdfFileReader(file(path, "rb"))
    # Iterate pages
    for i in range(0, pdf.getNumPages()):
        # Extract text from page and add to content
        content += pdf.getPage(i).extractText() + "\n"
    # Collapse whitespace
    content = " ".join(content.replace(u"\xa0", " ").strip().split())
    return content

#print getPDFContent(r"Z:\GIS\MasterPermits\12300983.pdf").encode("ascii", "ignore")


#find pdfs            
for root, dirs, files in os.walk(folder1):
    for file in files:
      if file.endswith(('.pdf')):
          d=os.path.join(root, file)
          print getPDFContent(d).encode("ascii", "ignore")

Traceback (most recent call last):
  File "C:\Documents and Settings\dknight\Desktop\readpdf.py", line 50, in <module>
    print getPDFContent(d).encode("ascii", "ignore")
  File "C:\Documents and Settings\dknight\Desktop\readpdf.py", line 32, in getPDFContent
    pdf = pyPdf.PdfFileReader(file(path, "rb"))
TypeError: 'str' object is not callable

我正在使用一个列表,但我得到了完全相同的错误,我不认为这将是一个大问题,但现在它正在成为一个。我知道我能够在arcpy中解决类似的问题,但这没什么关系

尽量不要为变量名使用内置类型:

不要这样做:

for file in files:

请改为:

 for myfile in files:
