3. For this program, you will use the wo tables given at the end of description (Table 1 and Table 2). Write a program according to the following specifications(To be done in Python). [4.0 marks]

In the main function of the program, ask the user to enter a string, pass that string to a function called TrimSpacesAndComments. This function removes the comments and all the leading and trailing white spaces and returns back the pure code string.

For example if user enters M=M+1 // comments then it should return M=M+1

Next pass this pure code string to a function called ConvertToMachineCode, this function should:

• Print the type of the instruction A or C (an instruction starting with @ is A instruction, otherwise it is a C instruction)
• If the instruction is one of the instructions from Table 2 then this function should also print its binary value. For Example:

A=D+1: C Instruction: 1100110011001100

The Program should accept the stings in a loop and should only exit if user enters string Exit (ignoring the case).

Use if-else statements (nested/elif etc) to do the conversion to binary code. You have to handle only the five strings given in the table below.

Table 1

@20 \\ memory value

A=D+1 \\ next memory value

D+1; JGT

M=D+1;JLT \\ do the jump

@240 \\ stack pointer

Table 2
@20	0000000000010100
A=D+1	1100110011001100
D+1; JGT	1010101010101010
M=D+1;JLT	1001001001001000
@240	0000000011110000
