In Python, you do this instead:for key, value in some_dictionary.items(): print(f'$key: $value') To do the same in JavaScript make a function like this:function items(dict, fn) { return Object.keys(dict).map((key, i) => { return fn(key, dict[key], i) }) } Now you can...

Thecount()function returns an interator that produces consecutive integers, indefinitely. The first number can be passed as an argument, the default is zero. There is no upper bound argument (see the built-inxrange()for more control over the result set). In this example, the iteration stops ...

In Python, we have only a handful of such guarantees (you can safely mutate dict values while iterating over the keys and lists guarantee that the iterator looks-up consecutive indicies regardless of changes to the underlying list). I propose to remove the last two paragraphs and the example...

Python中的很多东西都是可迭代的,但并非全部都是序列。字典,文件对象,集合和生成器都是可迭代的,但是它们都不是序列。 my_set={2,3,5}my_dict={"name":"Ventsislav","age":24}my_file=open("file_name.txt")squares=(n**2forninmy_set)

# python code requires more than 19GB when extracting top sentences. # into a file of 3.32GB. This file is then loaded 'lines_per_chunk' lines at a # time into a Counter (dict subclass) object which still might take many GBs of # memory. By setting 'min_count', entries with co...
