how to make a calculator in Python programming? ​

Answer 1

To make a calculator in python?

Well, instead of writing a ton of code, there is a new command in python which could basically work as a calculator. Here it is:

eval(input())

If your input is print(2+5//3*7), it would print 9.

Hope it helps! :)

Answer:

from chatterbot import ChatBot

# naming the ChatBot calculator

# using mathematical evaluation logic

# the calculator AI will not learn with the user input

Bot = ChatBot(name = 'Calculator',

               read_only = True,                  

               logic_adapters = ["chatterbot.logic.MathematicalEvaluation"],                

               storage_adapter = "chatterbot.storage.SQLStorageAdapter")

   

# clear the screen and start the calculator

print('\033c')

print("Hello, I am a calculator. How may I help you?")

while (True):

   # take the input from the user

   user_input = input("me: ")

   

   # check if the user has typed quit to exit the prgram  

   if user_input.lower() == 'quit':

       print("Exiting")

       break

   # otherwise, evaluate the user input

   # print invalid input if the AI is unable to comprehend the input

   try:

       response = Bot.get_response(user_input)

       print("Calculator:", response)

   except:

       print("Calculator: Please enter valid input.")
