可以利用drop_duplicates()方法处理重复值,该方法的作用是基于指定的规则判断为重复值之后,删除重复值,其参数跟duplicated()完全相同。 例如, print(df.drop_duplicates()) #对所有列进行重复值判断并删除 print(df.drop_duplicates(subset='col1')) #对col1列进行重复值判断并删除 ...

Given an array of integers, return indices of the two numbers such that they add up to a specific target.You may assume that each input would have exactly one solution, and you may not use the same element twice.Example: Given nums = [2, 7, 11, 15], target = 9, Because ...
