getting the solution from Wolfram alpha in python

So I am working on an assistant where the user will ask for an answer for a math problem and wolfram alpha will return it.

My problem right now is: Wolfram alpha returns the next step of the math problem.

What I want: Wolfram alpha should return the answer in decimal or integer after solving the whole problem.

My code:

import wolframalpha

query = input("calculate: ")

client = wolframalpha.Client("TYXXXX-PXXXXXXXX2")

query = query.replace(" ", "")
res = client.query(' '.join(query))
answer = next(res.results).text
print("calculating..")
print(f"The answer is {answer}")

Example:

input: 2x = 5

The answer I am looking for:

output: 2.5

The answer I get right now: output: 5/2

input: 2x = 5 - 3

The answer I am looking for: output: x = 1

The answer I get: 2x = 2

In this way you can have the final solution provided by WolframAlpha (you just need to get the last element of the generator, instead of retrieving only the first one):

import wolframalpha

client = wolframalpha.Client(AppID)

response = client.query(input())

# Get the last item of the generator res.results
result = None
for result in response.results:
    pass
# You could have also simply used result = list(response.results)[-1]

if result is not None:
    print(f"The answer is {result.text}".format(result.text))

If you plan to use this program with simple linear equations using only the x variable then you could do something like this:

print("The answer is {}".format(eval(result.text.replace("x = ", ""))))

However, this would not work with inputs such as 2x=y+3.

Possible inputs include equations such as:

  • 2x=5
  • x-3=2x+2

etc.
