pdfplumber给fp.seekposAttributeError：'dict'对象没有属性'seek'

如何解决pdfplumber给fp.seekposAttributeError：'dict'对象没有属性'seek'

这是我的代码：

def main():    
    import combinedparser as cp
    from tkinter.filedialog import askopenfilenames

    files = askopenfilenames()
    print(files) #this gives the right files as a list of strings composed of path+filename


    def file_discriminator(func):
        def wrapper():
            results = []
            for item in files:
                if item.endswith('.pdf'):
                    print(item + 'is pdf')
                    func = f1(file = item)
                    results.append(item,Specimen_Output)
                else:
                    print(item + 'is text')
                    func = f2(file = item)
                    results.append(item,Specimen_Output)

        return wrapper


    @file_discriminator
    def parse_me(**functions):
        print(results)


    parse_me(f1 = cp.advparser(),f2 = cp.vikparser())

main（）

combinedparser.py具有两个功能：

def advparser(**file):
    import pdfplumber
    with pdfplumber.open(file) as pdf:  # opened fname and assigned it to the variable pdf
        page = pdf.pages[0]  # assigned index 0 of pages to the variable page
        text = page.extract_words()
    #followed by a series of python operations generating a dict named Specimen_Output
def vikparser(**file):
    with open(file,mode = 'r') as filename:
        Specimen_Output = {}
    #followed by a series of python operations generating a dict named Specimen_Output 

我有一个目录，其中随机散布着pdf和文本文件。我正在尝试使用装饰器@file_discriminator运行功能advparser，该功能使用pdfplumber和后续处理从目录中pdf文件上的pdf文件中提取可用信息；和vikparser对文本文件执行常规的文本文件处理。每个都应生成一个称为Specimen_Output的字典。当advparser是作为advparser（file）运行的单独的.py文件，导入了askopenfilename而不是其复数形式，并使用advparser（file = askopenfilename（））调用时，我得到了正确的结果。 vikparser也是如此（它正在查看带有readlines的文本文件）。但是，当我尝试从主模块执行此操作并使用父函数调用它们时，我无法使其正常工作。我已经尝试了几乎所有可能的排列方式，并在“文件”中使用了位置vs关键字参数。

当我修复因更改而造成的任何错误时，这是​​我最常见的错误：

Traceback (most recent call last):

我在做什么错？它在说什么dict对象，为什么当我尝试从askopenfilename（）单独调用每种类型时，pdfplumber为什么没有这个问题？我是一个新手编码员，整天都把头发弄乱了。谢谢！

解决方法

问题在于，file和advparser函数中的vikparser自变量实际上是命名自变量的字典，因为它用两个星号定义。所以当您以这种方式调用这些函数

func = f1(file = item)

file或advparser函数中的vikparser参数实际上等于{"file": "some_filename.pdf"}。

您需要解压缩参数：

def vikparser(**file):
    with open(file["file"],mode='r') as filename:
        pass

或仅在函数定义中使用单个file参数：

def vikparser(file):
    with open(file,mode='r') as filename:
        pass
