for language in set(favorite_languages.values()): print(language.title()) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 通过对包含重复元素的列表调用set(),可让python找出列表中独一无二的元素,并使用这些元素来创建一个集合。在第9行处,我们使用了set()来提取favorite_lan
Python indexes are zero-based, so the first item in a list has an index of 0, and the last item has an index of -1 or len(my_list) - 1. # Print the last N key-value pairs of a dictionary You can use the same approach to print the last N key-value pairs of a dictionary....
You can use the python functionvars()andpprint()to print current object properties and values in Python. Thevars()returns a dictionary containing the object’s attributes and their current values. We can then use thepprint()function to print the dictionary in a human-readable format. Thevars(...
在Python中,字典(dictionary)是一种非常常用的数据结构,用于存储键值对。当字典中的键值对较多时,如果直接使用print函数打印字典,可能会导致输出结果过长,不易于阅读。因此,我们需要将字典的内容按行显示,以提高可读性。 本文将向刚入行的小白开发者介绍如何实现Python字典的分行显示。 实现步骤 下面是实现Python字典分...

So if you expect your values to be nested, then this is not the solution for that as well. Use json.dumps() to Pretty Print a Dictionary in Python Within the Python json module, there is a function called dumps(), which converts a Python object into a JSON string. Aside from the ...
Pretty-print tabular data in Python, a library and a command-line utility. The main use cases of the library are: printing small tables without hassle: just one function call, formatting is guided by the data itself authoring tabular data for lightweight plain-text markup: multiple output form...
