Smart calculator in Python
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
# main python proghram response = [ 'Welcome to smart calculator' , 'My name is MONTY' , 'Thanks for enjoy with me ' , 'Sorry ,this is beyond my ability' ] # fetching tokens from the text command def extract_from_text(text): l = [] for t in text.split( ' ' ): try : l.append( float (t)) except ValueError: pass return l # calculating LCM def lcm(a,b): L = a if a>b else b while L< = a * b: if L % a = = 0 and L % b = = 0 : return L L + = 1 # calculating HCF def hcf(a,b): H = a if a<b else b while H> = 1 : if a % H = = 0 and b % H = = 0 : return H H - = 1 # Addition def add(a,b): return a + b # Subtraction def sub(a,b): return a - b # Multiplication def mul(a,b): return a * b # Division def div(a,b): return a / b # Remainder def mod(a,b): return a % b # Response to command # printing - "Thanks for enjoy with me" on exit def end(): print (response[ 2 ]) input ( 'press enter key to exit' ) exit() def myname(): print (response[ 1 ]) def sorry(): print (response[ 3 ]) # Operations - performed on the basis of text tokens operations = { 'ADD' :add, 'PLUS' :add, 'SUM' :add, 'ADDITION' :add, 'SUB' :sub, 'SUBTRACT' :sub, 'MINUS' :sub, 'DIFFERENCE' :sub, 'LCM' :lcm, 'HCF' :hcf, 'PRODUCT' :mul, 'MULTIPLY' :mul, 'MULTIPLICATION' :mul, 'DIVISION' :div, 'MOD' :mod, 'REMANDER' :mod, 'MODULAS' :mod} # commands commands = { 'NAME' :myname, 'EXIT' :end, 'END' :end, 'CLOSE' :end} print ( '--------------' + response[ 0 ] + '------------' ) print ( '--------------' + response[ 1 ] + '--------------------' ) while True : print () text = input ( 'enter your queries: ' ) for word in text.split( ' ' ): if word.upper() in operations.keys(): try : l = extract_from_text(text) r = operations[word.upper()] (l[ 0 ],l[ 1 ]) print (r) except : print ( 'something went wrong going plz enter again !!' ) finally : break elif word.upper() in commands.keys(): commands[word.upper()]() break else : sorry() |
