Code has to be in Python. You do not have to include the extra credit portion.

In this project students vill build a scientific calculator on the command line. The program will display a menu of options vhich includes several arithmetic operations as well as options to clear the resull, display statistics. and exit the program. The project is designed to give students an opportunity to practice looping, type conversion, and data persistence. Specification When the program starts it should display a menu, prompt the user to enter a menu option, and read a value: Current Result: 0.0 Calculator Menu 0. Exit progran 1. Addition 2.

Operational Behavior This calculator includes multiple behaviors that are unique depending on the input and operation specified; they are detailed in this section. Exponentiation For exponentiation, the first operand should be used as the base and the second as the exponent, i.e: If the first operand is 2 and the second is 4.24=16 Logarithm For logarithms, the first operand should be used as the base and the second as the yleld, L.e.: If the first operand is 2 and the second is 4log24=2 (Hint Use python math tbrary) Displaying the Averege As the program progresses, a should store the total of all resilts of calculation and the number of Nole that this does not include the staring vilue of of The propram chould display the averege of : calculations as followns: Sun of calculations: 102.3 Number of calculations: 2 Averaoe of calculations: 50.15 Note that the average calculation should show a maximum of two decimal places The program should immediately prompt the user for the next menu option (without redisplaying the menu). If no calculations have been performed, this message should be displayed Error: no calculations yet to average! Extra Credit Using Results of Calculation You can earn 5% extra credit on this project by allowing the user to use the previous result in an operation. To add this feature, allow the user to enter the word "RESULT" in place of an operand; if the user does so, the program should replace this operand with the result of the previous calculation (or zero if this is the first calculation): Enter first operand: 89.1 Enter second operand: RESULT ) Submlssions NOTE: Your output must match the eximpls oulpit "exacty".
