With Python, a string is measured through the len() function.

The len() function is a built-in PHP function that can measure any argument put it into it, whether a string or a number.

The function simply counts the number of characters.

The code to measure a string is shown below.

The line above measures the name, David, and it will return a value of 5.

The above code outputs the length of a string directly inserted to it.

To measure the length of a variable, simply enter in the variable into the len() function after it is initialized.

The code to do this is shown below.

This returns a value of 8, since Jonathan has 8 characters.
