In case the key-based mapping and the keyword arguments have the same key, it throws a TypeError. If keys are missing it returns a KeyError. 2. safe_substitute(mapping, **kwds): The behavior of this method is similar to that of the substitute method but it doesn’t throw a KeyError if a key is missing, rather it returns a placeholder in the result string. The substitute() method raises a KeyError when a placeholder is not supplied in a dictionary or a keyword argument.
