Need urgent help in this question of Automata Programming Paradigm

[Satvik]

The question is; Write a deterministic automata code for the language with ∑ = {0, 1} accepts the only input 101.

My classmate sent the following code but it doesnt seem to work. PLEASE HELP.

Code:

from automata.fa.dfa import DFA
dfa=DFA(
  states={'q0','q1','q2','q3'},
  inputs symbols={'0','1'},
  transitions={
  'q0':{'0':'q0','1':'q1'}
  'q1':{'0':'q2','1':'q1'}
  'q2':{'0':'q2','1':'q3'}
  'q3':{'0':'q3','1':'q3'}
  },
  initial state='q0',
  final state={'q3'}
)
dfa.read_input('101') #answer is '101'
dfa.read_input('010') #answer is 'error'
if dfa.accepts_inputs('101'):
   print('accepted')
else:
   print('rejected')

What doesn't work. Does it give the wrong output or does it report an error and quit? If an error, pleas post the entire error message, including any traceback.

dfa.read_input('101') should return 'q3'
dfa.read_input('010') should return 'q2'

You should tell your friend the transitions map is incorrect. I am pretty sure it would accept '0101' or '1101' or '1011010101' or many other combinations.

To test your solution you need more test cases. I think you would learn quite a lot from using read_input_stepwise.

I edited the code a bit.

from automata.fa.dfa 
import DFA
dfa=DFA(
    states={'q0','q1','q2','q3'},
    inputs_symbols= {'0','1'},
    transitions={
    'q0':{'0':'q0','1':'q1'},
    'q1':{'0':'q2','1':'q1'},
    'q2':{'0':'q2','1':'q3'},
    'q3':{'0':'q3','1':'q3'}
    },
    initial_state='q0',
    final_state={'q3'}
    )
dfa.read_input('101') #answer is '101'
dfa.read_input('010') #answer is 'error'
if dfa.accepts_inputs('101'):
    print('accepted')
else:
    print('rejected')

The following is the error:
File "<ipython-input-1-427c1524b6c1>", line 1

SyntaxError: invalid syntax

you cannot split from automata.fa.dfa import DFA on 2 lines.

Still doesn't work. I am really new to python and coding.
This is the error:

ModuleNotFoundError Traceback (most recent call last)

probably that package
https://pypi.org/project/automata-lib/
https://github.com/caleb531/automata
did you install it?
