I tried the below what is given in the official documentation
>>> a = DIV(SPAN('a', 'b'), 'c')
>>> print a
<div><span>ab</span>c</div>
>>> del a[1]
>>> a.append(B('x'))
>>> a[0][0] = 'y'
>>> print a
<div><span>yb</span><b>x</b></div>
I typed
>>>a = DIV(SPAN('a', 'b'), 'c')
>>>print a
<div><span>ab</span>c</div>
but when I typed
>>> del a[1]
>>> a.append(B('x'))
>>> a[0][0] = 'y'
>>> print a
<div><span>ab</span>c</div>
It returned <div><span>ab</span>c</div>,nothing changed?
I got confused.
What is the reason?
TKS!
