ruby trim spaces
To trim spaces in a Ruby string, you can use the strip
method. Here is an explanation of the steps involved:
Create a string: Start by creating a string variable that contains the text you want to trim. For example, you can create a string like this:
text = " hello world "
.Call the
strip
method: Next, call thestrip
method on the string variable. This method removes leading and trailing whitespace from the string. In our example, you would usetrimmed_text = text.strip
.Observe the result: The
strip
method will return a new string with the leading and trailing spaces removed. In our example,trimmed_text
will contain the value"hello world"
.
It's important to note that the strip
method does not modify the original string; it returns a new string with the trimmed version. If you want to modify the original string, you can use the strip!
method instead (with an exclamation mark at the end), like this: text.strip!
.
Here's an example that puts it all together:
text = " hello world "
trimmed_text = text.strip
puts trimmed_text
This will output:
hello world
That's it! You have successfully trimmed spaces from a Ruby string using the strip
method.
