Definition and Usage. The rfind () method finds the last occurrence of the specified value. The rfind () method returns -1 if the value is not found. The rfind () method is almost the same as the rindex () method. See example below.The !r string format is a convenient one to use in certain cases. It is related closely to the __repr__() dunder method; and this method and the __str__() are often discussed together. In this post, we review __repr__() and __str__() methods and then the !r string format.. An usage example of the string format !r:
