1. Extract PDF content

# pip install PyPDF2  安装 PyPDF2
import PyPDF2
from PyPDF2 import PdfFileReader
 
# Creating a pdf file object.
pdf = open("test.pdf", "rb")
 
# Creating pdf reader object.
pdf_reader = PyPDF2.PdfFileReader(pdf)
 
# Checking total number of pages in a pdf file.
print("Total number of Pages:", pdf_reader.numPages)
 
# Creating a page object.
page = pdf_reader.getPage(200)
 
# Extract data from a specific page number.
print(page.extractText())
 
# Closing the object.
pdf.close()

2. Extract Word content

# pip install python-docx  安装 python-docx


import docx
 
 
def main():
    try:
        doc = docx.Document('test.docx')  # Creating word reader object.
        data = ""
        fullText = []
        for para in doc.paragraphs:
            fullText.append(para.text)
            data = '\n'.join(fullText)
 
        print(data)
 
    except IOError:
        print('There was an error opening the file!')
        return
 
 
if __name__ == '__main__':
    main()

3. Extract web page content

import requests
import json

r = requests.get("https://support.oneskyapp.com/hc/en-us/article_attachments/202761727/example_2.json")
res = r.json()

# Extract specific node content.
print(res['quiz']['sport'])

# Dump data as string
data = json.dumps(res)
print(data)

4. Read CSV data

import csv

with open('test.csv','r') as csv_file:
    reader =csv.reader(csv_file)
    next(reader) # Skip first row
    for row in reader:
        print(row)

5. Read Json data

import requests
import json

r = requests.get("https://support.oneskyapp.com/hc/en-us/article_attachments/202761727/example_2.json")
res = r.json()

# Extract specific node content.
print(res['quiz']['sport'])

# Dump data as string
data = json.dumps(res)
print(data)
