Which is the effective way to trim the leading and trailing white spaces of string variable in Go?

To remove leading and trailing spaces in Java, use the trim() method. This method returns a copy of this string with leading and trailing white space removed, or this string if it has no leading or trailing white space.
trim() The trim() method removes whitespace from both ends of a string and returns a new string, without modifying the original string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.)
TRIM function - remove extra spaces in Excel You use the TRIM function in Excel removes extra spaces from text. It deletes all leading, trailing and in-between spaces except for a single space character between words.
strip(): returns a new string after removing any leading and trailing whitespaces including tabs (\t). rstrip(): returns a new string with trailing whitespace removed.
For example,
package main import ( "fmt" "strings" ) func main() { s := "\t Hello, World\n " fmt.Printf("%d %q\n", len(s), s) t := strings.TrimSpace(s) fmt.Printf("%d %q\n", len(t), t) } Output:
16 "\t Hello, World\n " 12 "Hello, World" There's a bunch of functions to trim strings in go.
See them there : Trim
Here's an example, adapted from the documentation, removing leading and trailing white spaces :
fmt.Printf("[%q]", strings.Trim(" Achtung ", " ")) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
