# Appending to the contents of 'title' tag in html file
print("Current content in title tag is:-")
print(soup.title)
soup.title.append("Using BS")
print("Content after appending is:-")
print(soup.title)
  
print("\n")
  
# Appending to the contents of 'h1' tag in html file
print("Current content in heading h1 tag is:-")
print(soup.h1)
soup.h1.append("contents of tag")
print("Content after appending is:-")
print(soup.h1)
  
print("\n")
  
# Appending to the contents of 'p' tag in html file
print("Current content in paragraph p tag is:-")
print(soup.p)
soup.p.append("BeautifulSoup library")
print("Content after appending is:-")
print(soup.p)
  
print("\n")
  
# Appending to the contents of 'a' tag in html file
print("Current content in anchor a tag is:-")
print(soup.a)
soup.a.append("Geeks Website")
print("Content after appending is:-")
print(soup.a)
  
# Code to save the changes in 'output.html' file
savechanges = soup.prettify("utf-8")

    file.write(savechanges)
