Example: Based on a list of fruits, you want a new list, containing only the fruits with the letter "a" in the name. Examples >>> df = pd. kann das) Und was ist ein Tupel. Using the append function we just added the values to the dictionary. The objects stored in a list or tuple can be of any type, including the nothing type defined by the None keyword. play_arrow.
