Why Do Single Quotes Cause Errors When Assigning Strings in Go?

Unable to Assign String Enclosed in Single Quotes in Go

In Go, attempting to assign a string enclosed in single quotes will result in an error, while double quotes are accepted. This behavior stems from the distinction between a rune (a single character) and a string:

• A rune is represented by single quotes ('⌘'), e.g.: a = '⌘'.
• A string contains one or more characters and is represented by double quotes ("⌘"), e.g.: a = "⌘".

This distinction exists in various programming languages, such as C , to differentiate between characters and strings.

Although Python and Perl allow strings to be enclosed in either single or double quotes, Go follows a strict delineation. This is due to Go's focus on type safety and its use of runes as the fundamental building block of strings.

As a result, when assigning a string to a variable, you must enclose it in double quotes. Enclosing it in single quotes will lead to an error, as illustrated in the examples provided.
