Python-119 cannot open terminal

1. 首先，发现pycharm里报错，即：不能打开terminal，这样一来pip安装各种包也无法安装；用以下方法来解决这个问题：

File ---settings---tools ---terminal, 把shell.exe改成cmd.exe然后重启pycharm,再点击terminal，即可正常运行！

2. PDF文件进行split，并按页输出：具体代码如下，只需要改一下原始pdf文件路径和输出位置，点击运行即可！

• 注意：输出文件会存放在制定的output位置！这点务必注意！如果没有设置，则会存在默认工作目录下！

# pdf_splitter.py

import os
from PyPDF2 import PdfFileReader, PdfFileWriter

def pdf_splitter(path):
    fname = os.path.splitext(os.path.basename(path))[0]

    pdf = PdfFileReader(path)
    for page in range(pdf.getNumPages()):
        pdf_writer = PdfFileWriter()
        pdf_writer.addPage(pdf.getPage(page))
#where to output the results 
        output_filename = 'C:\\Users\\Administrator\\Desktop\\split\\毛螺菌科文献{}_page_{}.pdf'.format(
            fname, page+1)

        with open(output_filename, 'wb') as out:
            pdf_writer.write(out)

        print('Created: {}'.format(output_filename))
if __name__ == '__main__':
    #original  PDF file to be splitted
    path = 'C:\\Users\\Administrator\\Desktop\\毛螺菌科文献.pdf'
    pdf_splitter(path)
