Get keywords from YouTube video meta tag.

March 2, 2019

My wife was wanting to see meta tags embedded in YouTube videos so I whipped up this quick Python script.

Install Python 3

Install Beautiful Soup
Ubuntu:

sudo apt-get install python3-bs4
sudo apt-get install python-lxml

PIP:

python3 -m pip install BeautifulSoup4
python3 -m pip install lxml

import urllib.request
from bs4 import BeautifulSoup  

url = 'https://www.youtube.com/watch?v=BWYiMcH0cRc'

print('URL: %s' % url)
print('*' * 60)

request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
soup = BeautifulSoup(response,"lxml")

keywords = soup.find("meta", {"name":"keywords"})['content']
for keyword in keywords.split(','): 
    print(keyword.strip())

Result:
URL: https://www.youtube.com/watch?v=BWYiMcH0cRc

Make it a simple Tk application:

import urllib.request
from bs4 import BeautifulSoup  
from tkinter import *

def get_keywords():
    url = entry.get()
    if not url: return

    listbox.delete(0, END)
    request = urllib.request.Request(url)
    response = urllib.request.urlopen(request)
    soup = BeautifulSoup(response,"lxml")

    keywords = soup.find("meta", {"name":"keywords"})['content']
    for id,keyword in enumerate(keywords.split(',')): 
        #print(keyword.strip())
        listbox.insert(id, keyword.strip())
    entry.delete(0, END)
    entry.focus()

def close_window (): 
    root.destroy()

root = Tk()

root.title('Keywords')
root.geometry("640x480") 
root.resizable(0, 0)

topframe = Frame(root)
topframe.pack(side = TOP, fill = X)

label = Label(topframe, text = "URL")
label.pack(side = LEFT)

entry = Entry(topframe, bd = 1)
entry.pack(fill = X)
entry.focus()

buttonframe = Frame(root)
buttonframe.pack(side = BOTTOM, fill = X)

button_run = Button(buttonframe, text="Run", command=get_keywords)
button_run.pack(side = RIGHT)
button_close = Button(buttonframe, text="Close", command=close_window)
button_close.pack(side = LEFT)

bottomframe = Frame(root)
bottomframe.pack(side = BOTTOM, fill = BOTH, expand = 1)

listbox = Listbox(bottomframe)
listbox.pack(side = LEFT, fill = BOTH, expand = 1)

root.mainloop()
