Summary

In Golang, string formatting is a versatile feature provided primarily by the built-in fmt package, which offers methods like Printf and Sprintf for converting various data types into formatted strings. These methods utilize special characters called verbs, such as %v for general object representation, %+v for printing objects with field names, and %T for identifying data types, which are particularly useful for debugging. The package also allows for detailed formatting of numbers, such as converting integers to base-16 with the %x verb or formatting floating-point numbers with options like %f for decimal representation and %e for scientific notation. Additional functionalities include setting the width of formatted strings, adding leading or trailing zeros, and handling escaped syntax in strings using verbs like %s and %q. Golang’s string literals, delineated by backticks, facilitate creating multiline strings and incorporating special characters, enhancing the ease with which developers can manipulate and display strings.
