data.groupby( column_1 )[ column_2 ].apply(sum).reset_index() 1. 按一个列分组,选择另一个列来执行一个函数。.reset_index() 会将数据重构成一个表。 正如前面解释过的,为了优化代码,在一行中将你的函数连接起来。 行迭代 dictionary = {} for i,row in data.iterrows(): dictionary[row[ column...
citys = ['ny','zz','xy'] #在第0列,加上column名称为city,值为citys的数值。 df.insert(0,'city',citys) jobs = ['student','AI','teacher'] # 默认在df最后一列加上column名称为job,值为jobs的数据。 df['job'] = jobs #若df中没有index为“4”的这一行的话,则添加,否则修改 df.loc...

A columnar transposition, also known as a row-column transpose, is a very simple cipher to perform by hand. First, you write your message in columns. Then, you just rearrange the columns. For example. I have the message, Which wristwatches are swiss wristwatches. You convert everything ...
