Python实现PDF合并

def str_to_int(str):
    '''
    Convert string to int

    param:: "str": string

    return:: "x":int
    '''
    str1 = re.sub(' ','',str)
    print(str1)
    assert str1.isdigit(),"Please input the current index!"
    x = []
    slen = len(str)
    i = 0
    s = 0
    f = 0

2 、pdf_file_list()函数：pdf文件搜索函数 
def pdf_file_list(fpath):
    """
    Get paths of all pdf files


    param:: "fpath":The root path

    return:: "pdf_paths":The paths of all pdf files
    """
    assert os.path.exists(fpath), 'The folder path does not exist'
    pdf_paths = list()
    for root, dirs, files in os.walk(fpath):
        for file in files:
            if file.endswith('.pdf'):
                pdf_paths.append(os.path.join(root, file))
    return pdf_paths

 
3、pdf_merge()函数：pdf拼接函数 
def pdf_merge(fpath):
    """
    Merge the pdf files

    param:: "fpath":The paths of pdf

    return:: None 
    """
    fmerge = PyPDF2.PdfFileMerger()
    for pdf in fpath:
        fmerge.append(pdf)
    fmerge.write('result.pdf')
