python 3.x - Python3 Write to file beautifulsoup -

i wish write beautifulsoup form code:

soup = beautifulsoup(con.content) f = open('/*/*/desktop/littletext.rtf','w') f.write(str(soup)) f.close() 

i error:

traceback (most recent call last): file "///desktop/test123.py", line 10, in f.write(soup) typeerror: must str, not beautifulsoup

any ideas how fix this? tried convert 'soup' string didn't work -- f.write(str(soup))

found out problem had use 'wb' in f = open('/*/*/desktop/littletext.rtf','wb') , f.write(str(soup)) had f.write(soup.encode('utf-8'))
