Preface Errors are problems in a program so that the program stops executing. Exceptions are raised, on the other hand, when some internal event occurs that alter the normal process of the program. Two types of errors occur in python. Syntax error Logical error (Exceptions) 1. Syntax error When the proper syntax of the language […]

Preface When doing homework on competitive programming websites, many people have encountered NZEC errors. NZEC (short for Non zero exit code) occurs when your code does not return 0. When the code returns 0, it means it was executed successfully, otherwise it will return some price. Other values ​​depend on the type of error. When […]

Preface Using loops in Python efficiently automates and repeats tasks. But sometimes, it may arise a condition in which you want to exit the loop entirely, skip an iteration, or ignore that condition. These can be done with loop control statements. The loop control statements change execution from its normal sequence. When execution leaves a […]

Preface There are real life situations where we need to make certain decisions and based on these decisions, we decide what to do next. Similar situations arise in programming when we need to make some decisions and based on these decisions we execute the next block of code. The decision statements in a programming language […]

Preface In Python, some math can be done easily by importing a module called “math”, which defines many different functions, which helps in performing the math tasks of we become easier. 1. Function ceil (): This function returns the smallest integer value that is greater than the number passed, that is, this function returns the […]

Preface This lesson will cover the problem of connecting to database in Python program. It can be said that connecting a program to a database is seen as a difficult task in any programming language. It is used to connect the front-end part of your application to the back-end database part. Python along with built-in […]

Preface This article will talk about trigonometric and angular functions. 1. Sin () function: This function returns the sine value of the argument passed to the function. Arguments passed to this function must be in radians. 2. Function cos (): This function returns the cosine value of the argument passed to the function. Arguments passed […]

Preface Sometimes, as part of our programming work, we have to work with databases, because we want to store a huge amount of information inside our application, so we need it. to other databases, such as Oracle, MySQL, etc. So, in this article, we will learn about connecting to an Oracle database using Python. This […]

Preface In the previous articles, we see that the number of database records mentioned in the examples is limited to a relatively small amount, and the data is organized in a fairly simple fashion. In this article, we will learn about how to write (write) and fetch (fetch) big data from the database using the […]

Preface In this article, we will learn about how to remotely connect to a MySQL database using Python. Storing data on a server for easy access is crucial for every application. Connecting remotely to a database is relatively complex because neither the service providers provide remote access to the mysql database. In this article, we […]
