Calculator Using Python 3

Today I will show you how you can make a simple calculator using python 3, I made this in my 1st semester, kindly find the code below and make sure to understand it well:

import math
	print(" >>> CONSOLED BASED CALCULATOR >>> \n " )
	print("This is a consoled Based Calculator , This allowed a user to perform the \n under lying operations:")
	print(" >>> Addition \n >>> Subtraction \n >>> Multiplication \n >>> Division \n >>> log \n >>> exponent ")
	print("this is also specially designed for the convertion of a number from degree to radian and vice versa")
	print("More Over the calculator also allows the user to perform 'TRIGNOMETRIC AND HYPERBOLIC FUNCTIONS' \n like : cos,sin,tan and inverse of all \n also cosh,sinh,tanh and their inverses ")
	print("'SO GO ON AND USE IT WELL'")
	# CODE FOR CONSOLED BASED CALCULATOR IN PYTHON 3 :
	def arthCalculator(num01,num02,operator):
	if operator == "+" :
	print(num01 + num02)
	elif operator == "-":
	print(num01 - num02)
	elif operator == "*":
	print(num01 * num02)
	elif operator == "/":
	try:
	result = num01 / num02
	except :
	print("Zero Division Error")
	else:
	print(num01 / num02)
	elif operator == "log":
	num = int(input("Enter only one number for applying log:"))
	print(math.log10(num))
	elif operator == "exponent":
	number = int(input("Enter only one number for exponent:"))
	print(math.exp(number))
	choice = input("Do you Want to perform trignometric and hyperbolic function(Yes or No):") # CHOOSE YES OR NO FOR GOING INTO TRIGNOMETRIC OR HYPERBOLIC CALCULATIONS
	if choice == "Yes":
	number = int(input("Enter one number to perform trignometric and hyperbolic functions:"))
	operator = input("Enter any trignometric or hyperbolic function like ; cos , sin , tan etc... :") # THIS OPERATOR IS ESPECIALLY FOR TRIGNOMETRIC OR HYPERBOLIC CALCULATIONS
	if operator == "cos":
	print(math.cos(number))
	elif operator == "sin":
	print(math.sin(number))
	elif operator == "tan":
	print(math.tan(number))
	elif operator == "acos":
	print(math.acos(number))
	elif operator == "asin":
	print(math.asin(number))
	elif operator == "atan":
	print(math.atan(number))
	elif operator == "cosh":
	print(math.cosh(number))
	elif operator == "sinh":
	print(math.sinh(number))
	elif operator == "tanh":
	print(math.tanh(number))
	elif operator == "acosh":
	print(math.acosh(number))
	elif operator == "asinh":
	print(math.asinh(number))
	elif operator == "atanh":
	print(math.atanh(number))
	else:
	print("Ok")
	convertion = input("Do you Want convertioN of any number from degree to radian or vice versa ('yes' or 'no')")
	if convertion == "yes":
	number = int(input("Enter a number to convert it from degree to radians or vice versa:")) # INPUT NUMBER FOR : Convert it from degree to radian or vice versa
	convertionF = input("choose convertion:'From radian to degree' or 'From degree to radian' :") # INPUT CONVERT FROM WHAT TO WHAT
	if convertionF == "From radian to degree":
	print(math.degrees(number))
	elif convertionF == "From degree to radian":
	print(math.radians(number))
	else:
	print("Ok")
	def main():
	num01 = input("Enter a number 01:")
	num02 = input("Enter a number 02:")
	operator = input("Enter any operator from + , - , * , / , log , exponent :")
	try:
	num01 = int(num01)
	num02 = int(num02)
	except:
	print("Invalid number")
	else:
	arthCalculator(num01,num02,operator)
	main() -------------------------------------------------------------------- HAPPY CODING :)
