In other words, we start from index 2 and go to the end of the list, since no other integer is specified. What happens now when we do the reverse, you think? Find out if you’re right by running the code chunk above! You see that now we only get back bear and lion. Now we ...
For the set, it’s either there or it’s not; there’no index or key: >>> marx_list = ['Groucho', 'Chico', 'Harpo'] >>> marx_tuple = ('Groucho', 'Chico', 'Harpo') >>> marx_dict = {'Groucho': 'banjo', 'Chico': 'piano', 'Harpo': 'harp'} >>> marx_set = {'Gro...

Python's development never completely stops between releases, and a steady flow of bug fixes and improvements are always being submitted. A host of minor fixes, a few optimizations, additional docstrings, and better error messages went into 2.0; to list them all would be impossible, but they'...

Thezip()function in Python is used to “zip” orcombine two or more lists into a single iterable object, which can then be looped over or converted into a list. For example, if we have two lists,list1andlist2, we can use the zip() function to create a new list that contains tuple...
filteris a function used quite frequently in list manipulation. Nomally it will setup some filtering function and return a sublist of the list according to the filter. For example, you wanna find all the elements meeting the lower bound, you would do something like this: ...
