Using CX_Freeze in Python
Sometimes we feel to create something different which is very exciting, and according to human nature, we always love to share it. Python also fulfills those wishes. Using Python, if we want to share our Python program with our friends we can do that, only need to have the same version of Python installed with all the modules those are used in program of their machine. First we need to install CX_Freeze module using pip install CX_Frezze command in command prompt. First step is to solve this assignment, a python program conversion. We need standard library modules, here we ...
Read MoreDecimal Functions in Python
In Python, there is a module called Decimal, which is used to do some decimal floating point related tasks. This module provides correctly-rounded floating point arithmetic. To use it at first we need to import it the Decimal standard library module. import decimal In this section we will see some important functions of the Decimal module. The square root function sqrt() and Exponent function exp() The sqrt() method is used to calculate the square root of a given decimal type object. And the exp() method returns the e^x value for the given x as Decimal number. Example Code ...
Read MoreText Analysis in Python3
In this assignment we work with files. Files are everywhere in this Universe. In computer system files are essential part. Operating system consists a lot of files. Python has two types of files-Text Files and Binary Files. Here we discuss about Text Files Here we focus some of the important functions on files. Number of words Number of characters Average word length Number of stop words Number of special characters Number of numeric Number of uppercase words We have a test file "css3.txt", we are working on that file Number of words When we count number of ...
Read MoreInstruction type MOV r1, r2 in 8085 Microprocessor
In 8085 Instruction set, MOV is a mnemonic, which stands for “MOVe”. In this instruction 8-bit data value in register r2 will be moved to the 8-bit register r1. Note that in 8085 instructions, as the first operand specifies the destination, and the second one the source, so here also r1 is destination register and r2 is the source register. This instruction uses register addressing for specifying the data. Here, “r1” and “r2”can be any one of the following registers. r1, r2 = A, B, C, D, E, H, or L As r1 can have any one of ...
Read MorePython program to check if there are K consecutive 1's in a binary number?
First we take a user input string with the combination of 1’s and 0’s.then create a new string with 1’s, then check if there is any p number of consecutive 1’s is present or not. If present then display FOUND otherwise NOTFOUND. Example Binary number ::1111001111 Enter consecutive 1’s :3 Consecutive 1's is Found Algorithm Step 1: input a string with the combination of 1’s, it’s stored in the variable X and 0’s and p is the consecutive 1’s in a binary number. Step 2: form a new string of p 1’s. newstring=”1”*p Step ...
Read MoreRead and Write to an excel file using Python openpyxl module
Python provides openpyxl module for operating with Excel files. How to create Excel files, how to write, read etc. can be implemented by this module. For installing openpyxl module, we can write this command in command prompt pip install openpyxl If we want to give a sheet title name Example code import openpyxl my_wb = openpyxl.Workbook() my_sheet = my_wb.active my_sheet_title = my_sheet.title print("My sheet title: " + my_sheet_title) Output My sheet title:Sheet To change Title Name Example code import openpyxl my_wb = openpyxl.Workbook() my_sheet = my_wb.active my_sheet.title = "My New Sheet" print("sheet name ...
Read MoreInstruction type LDA a16 in 8085 Microprocessor
In 8085 Instruction set, LDA is a mnemonic that stands for LoaD Accumulator with the contents from memory. In this instructionAccumulatorwill get initialized with 8-bit content from the 16-bit memory address as indicated in the instruction as a16. This instruction uses absolute addressing for specifying the data. It occupies 3-Bytes in the memory. First Byte specifies the opcode, and the successive 2-Bytes provide the 16-bit address, i.e. 1-Byte each for each memory location. Mnemonics, Operand Opcode(in HEX) Bytes LDA Address 3A 3 Let us consider LDA 4050H as an example instruction of this type. ...
Read MoreInstruction type XCHG in 8085 Microprocessor
In 8085 Instruction set, there is one mnemonic XCHG, which stands for eXCHanGe. This is an instruction to exchange contents of HL register pair with DE register pair. This instruction uses implied addressing mode. As it is1-Byte instruction, so It occupies only 1-Byte in the memory. After execution of this instruction, the content between H and D registers and L and E registers will get swapped respectively. Mnemonics, Operand Opcode(in HEX) Bytes XCHG EB 1 Let us suppose, HL and DE register pairs are having ABCDH and 6789H contents respectively. After execution of ...
Read MoreInstruction type STAX rp in 8085 Microprocessor
In 8085 Instruction set, STAX is a mnemonic that stands for SToreAccumulator contents in memory pointed by eXtended register denoted as “rp”.Hererp stands for register pair. This instruction uses register indirect addressing for specifying the destination. So using this instruction, the current content of Accumulator will be written to the memory location as pointed by 16-bit address as stored in the register pair. It occupies only 1-Byte in memory. Mnemonics, Operand Opcode(in HEX) Bytes STAX B 02 1 STAX D 12 1 STAX B is an example instruction of this type. It ...
Read MoreInstruction type SHLD a16 in 8085 Microprocessor
In 8085 Instruction set, SHLD is a mnemonic, which stands for Store HLpair using Direct addressing in memory location whose 16-bit address is denoted as a16. As HL pair has to be stored, so it has to be stored in two consecutive locations starting at the address a16. We know that H and L are 8-bit registers. So their contents will be stored in two consecutive memory locations as each memory location can hold 8-bits of data. This instruction uses absolute addressing mode for specifying the destination. It occupies 3-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes ...
