A form *isn't* a dictionary, this means that your code :
form['passwd'] = 'surese'

is wrong.
Turn the form into a dictionary and use that.
Why are you trying to assign values directly in the form ?

How Can I convert a form instance into dictionary
Kindly let me know.

What have you tried ? ;-)

def form_to_dict(form):
out_dict = {}
for entry in form:
out_dict[entry] = form[entry].value
return out_dict

UNTESTED AND FROM MEMORY
If it doesn't work - try reading the manual to see what I did
wrong.....

Why are you trying to assign values directly in the
form ?

To reduce variable usage in my project.

At the cost of clarity ? Not a worthwhile trade off. Explicity delet
variables you have finished with instead.

form = cgi.FieldStorage()
formdict = form_to_dict(form)
del form
