The str() function in Python is used to convert any data type into a string. It takes an object as an argument and returns a string representation of that object. This function is particularly useful when we need to concatenate strings with other data types like integers or floats. It can also be used to format strings by inserting variables into a string using placeholders. The str() function is a built-in function in Python, which means it is available for use without the need for any additional libraries or modules. Keep reading below to learn how to python str in Go.

Python ‘str’ in Go With Example Code
Python is a popular programming language that is widely used for various purposes. One of its key features is its string manipulation capabilities. However, if you are a Go developer, you may be wondering how to achieve similar functionality in Go. In this blog post, we will explore how to work with strings in Go.
Go has a built-in package called “strings” that provides a variety of functions for working with strings. One of the most commonly used functions is “strings.Contains”, which checks whether a string contains a specific substring. Here is an example:
package main
import (
"fmt"
"strings"
)
func main() {
str := "Hello, world!"
if strings.Contains(str, "world") {
fmt.Println("The string contains 'world'")
} else {
fmt.Println("The string does not contain 'world'")
}
}
This code checks whether the string “Hello, world!” contains the substring “world”. If it does, it prints “The string contains ‘world'”. Otherwise, it prints “The string does not contain ‘world'”.
Another useful function in the “strings” package is “strings.Replace”, which replaces all occurrences of a substring with another substring. Here is an example:
package main
import (
"fmt"
"strings"
)
func main() {
str := "Hello, world!"
newStr := strings.Replace(str, "world", "Go", -1)
fmt.Println(newStr)
}
This code replaces all occurrences of the substring “world” with “Go” in the string “Hello, world!”. The “-1” parameter indicates that all occurrences should be replaced.
In addition to these functions, the “strings” package provides many other useful functions for working with strings in Go. By familiarizing yourself with these functions, you can achieve similar string manipulation capabilities as in Python.
Equivalent of Python str in Go
In conclusion, the equivalent function to Python’s str() in Go is the strconv.Itoa() function. This function converts an integer to its corresponding string representation. It is important to note that Go has a strong type system, which means that it is necessary to explicitly convert between types when working with different data types. The strconv package in Go provides a variety of functions for converting between different data types, including integers, floats, and booleans. By using the strconv.Itoa() function, developers can easily convert integers to strings in their Go programs. Overall, understanding the equivalent function to Python’s str() in Go is an important step for any developer looking to work with Go and manipulate data types effectively.
