Problem – This smart calculator works on the text statement also. The user need not provide algebraic expression always. It fetches the word form the command (given by the user) and then formulates the expression.
Examples:
Input : Hi calculator plz find the lcm of 4 and 8. Output : 8 Input : Hi smart plz find the multiplication of 3 and 9. Output : 27 Input : Hi smart plz end the program. Output : Thanks for enjoy with me.
Code : Python code for smart calculation
Python3

Output:
--------------Welcome to smart calculator------------ --------------My name is MONTY-------------------- enter your queries: tell me the hcf of 4 and 8 4.0 enter your queries: hi plz tell me 7 + 8 Sorry ,this is beyond my ability enter your queries: pls add 7 and 8 15.0
