In this tutorial, we will learn how to convert string type variables into int in Go programming language. For this task various types of string conversions are needed, to perform the conversions “strconv” package is imported in the go language program, Strings can be transformed into integer values using the ParseInt function. It decodes a string in the specified base (0, 2 to 36) and bit size (0, 64), and then it returns the equivalent result. Convert String Type Variable Into Int Syntax func ParseInt(s string, radix/base int, bitSize int) (i int64, err error) ParseInt() function is used to ... Read More
In this tutorial, we will learn how to f convert string type variables into Boolean in Go programming language. Boolean Vs String Boolean is a data type having 1-byte size. It can store any one of the three values mainly True, False or none. It acts like a flag to show whether a condition is correct or not. String data type is used to store a sequence of characters. it can be in the form of literals or alphabets. The size of string variable is 1 byte or 8 bits. For this task various types of string conversions are needed, ... Read More
In this article you will know how to convert the decimal number to octal in Go language. For this we are going to use the FormatInt() function of strconv package. When we say convert the decimal number to octal, it means to convert the number with the base value 10 to the base value 8. The base value means the number of digits required to represent the numeric value. Example 1: Go Language Program to convert Decimal Number to Octal using Library Function Syntax func FormatInt(input int64, base int) string for [condition | ( init; condition; increment) | Range] ...

In this article you will learn the go language code to convert decimal number to Hexadecimal. Decimal Number Vs Hexadecimal Numbers Decimal numbers are the numbers which have base 10, which means each digit of a number can have an integer value ranging from 0 to 9 (10 possibilities) depending on its position. For example, 23 is a decimal number. Any number contains 16 digits in it, it is based on base 16, which means hexadecimal numbers contains decimal number from 0 to 9 and extra 6 Alphabets. A−F. In go language all the hexadecimal numbers start with 0x or ... Read More
In this tutorial, we will learn how to convert Boolean to a string in Go programming language. Boolean Vs String Boolean is a data type having 1 byte size. It can store any one of the three values mainly True, False or none. It act like a flag to show whether a condition is correct or not. String data type is used to store a sequence of characters. it can be in the form of literals or alphabets. The size of string variable is 1 byte or 8 bits. Example 1: Convert Boolean type to String USING strconv.FormatBool() Method Syntax ... Read More
In this article we will discuss about how to check if a given number is odd using library function Go language. ODD NUMBERS − In mathematics any number is called odd if it gives “1” as remainder when divided by “2”. For example 1, 3, 5, 7 …. Even Numbers − unlike odd numbers even numbers get completely divided by “2” and do not produce any remainder. For example − 2, 4, 6, 8 … Syntax func Mod(number1, number2 float64) float64 The mod() function is defined in the math package. This function returns the remainder by dividing the two numbers ...

In this tutorial we will learn how to check if a given value is present in a Go−lang array or not. We will use 2 methods for this. Method 1: Using a for loop directly in the main function We will use a for loop to iterate over the elements of an array in Golang and check for the equality of values using the equality operator. If the values match then we can stop the iteration and say that the given value is present in the array. Method 2: Using the function Golang does not have any pre-defined library function ...

File descriptors in Python are identifiers that represents the open files in the os kernel and are kept in a table of files. Typically, they have non-negative values. Negative results denote an error or a "no value" condition. They support a variety of file-related operations. In general, descriptors are a special approach Python uses to maintain attributes. The main things they assist with are accessing files and other input/output devices like network sockets or pipes. These operations take place on I/O streams identified by following file descriptors − close( fd ) File descriptor closure. This function must be used with ... Read More
Applications can use the logging module to configure various log handlers and to route log messages to these handlers. This enables a very flexible design that can handle a wide range of use cases. A caller must first request a named logger in order to produce a log message. The program can set up various rules for various loggers using the name. The program can then utilise this logger to produce plain-text messages at various log levels (DEBUG, INFO, ERROR, etc.), allowing it to handle messages with a higher priority differently from those with a lower priority.Following is an example ...

The Python Standard Library is a collection of script modules that may be used by a Python program, making it unnecessary to rewrite frequently used commands and streamlining the development process. By "calling/importing" them at the start of a script, they can be used. A module is a file that contains Python code; an ‘coding.py’ file would be a module with the name ‘coding’.We utilise modules to divide complicated programmes into smaller, more manageable pieces. Modules also allow for the reuse of code. In the following example, a module called ‘coding’ contains a function called add() that we developed. The ... Read More
