A trouble with requests

[Truman]

# The following will return a list of 2-grams found in the Wikipedia article on the Python programming language:

import requests
from bs4 import BeautifulSoup

def getNgrams(input, n):
	input = input.split('')
	output = []
	for i in range(len(input)-n+1):
		output.append(input[i:i+n])
	return output
	
html = requests.get("https://en.wikipedia.org/wiki/Python_(programming_language)")
bsObj = BeautifulSoup(html.content, 'html.parser')
content = bsObj.find("div", {"id":"mw-content-text"}).get_text()
ngrams = getNgrams(content, 2)
print(ngrams)
print("2-grams count is: "+str(len(ngrams))) 

Error:

Any idea why these errors appear?
