Maintain two pointers pA and pB initialized at the head of A and B, respectively. Then let them both traverse through the lists, one node at a time. When pA reaches the end of a list, then redirect it to the head of B (yes, B, that's right.); similarly when pB reaches the end...

Thecollectionsmodule in Python provides theCounterclass, which can be used to find the intersection of dictionaries. fromcollectionsimportCounter dictA={'x ':1,'y':2,'z':3}dictB={'u':1,'v ':2,'w':3,'x':1,'y':2}common_keys=(Counter(dictA)&Counter(dictB)).keys()print(set(com...
1. pd创建df的时候,如果用字典的方式插入数据,如果字典每一个键只对应了一个值,也要以列表的形式插进去。比如{"dominic": ["ydx"]}这样子2. pd.cut用的时候要指定bin,cut完了还可以value_counts3. 用pd.qcut的话可以直接得到等距分割4. list 求差集:可以用推导式。但比较慢。Python内置的解法是:clist ...
