Write a Python function that accepts a list of strings and returns a list of tuples where the first element is the string and the second is the length of the string.
Example 1:
Input: ['Hello', 'Python', 'World']
Output: [('Hello', 5), ('Python', 6), ('World', 5)]
Example 2:
Input: ['OpenAI', 'GPT', 'ChatGPT']
Output: [('OpenAI', 6), ('GPT', 3), ('ChatGPT', 7)]
