ISCONVERDED 列取 [0 or 1] ：是否已转换。

我想做的是按日期分组，对于每个日期，当ISCONVERTED = '1' 时，我将得到百分比，在 ISCONVERTED = '0' 时得到百分比，如下所示：

| CREATEDDATE     | ISCONVERTED |
|-----------------|-------------|
| 01 January 21   | 1.000000    |
| 02 February 21  | 0.676471    |
| 02 February 21  | 0.323529    |
| 03 March 21     | 0.598909    |
| 03 March 21     | 0.401091    |
| 04 April 21     | 0.646900    |
| 04 April 21     | 0.353100    |
| 05 May 21       | 0.678363    |
| 05 May 21       | 0.321637    |
| 06 June 21      | 0.729231    |
| 06 June 21      | 0.270769    |
| 07 July 21      | 0.646586    |
| 07 July 21      | 0.353414    |
| 08 August 20    | 1.000000    |
| 08 August 21    | 0.553247    |
| 08 August 21    | 0.446753    |
| 09 September 21 | 0.597911    |
| 09 September 21 | 0.402089    |

我试过这段代码：

df= df.groupby(['CREATEDDATE'])['ISCONVERTED'].value_counts(normalize = True)

结果如下：

你有什么想法，我该如何解决这个问题？

【问题讨论】：

标签： python pandas dataframe pandas-groupby

【解决方案1】：

不确定您当前的解决方案缺少什么。如果您只需要一个 DataFrame，您可以重置索引，以便：

df= df.groupby(['CREATEDDATE'])['ISCONVERTED'].value_counts(normalize = True).rename('RATIO').reset_index()

如果您希望只有问题中显示的两列，则只需删除 ISCONVERTED 列：

df= df.groupby(['CREATEDDATE'])['ISCONVERTED'].value_counts(normalize = True).rename('RATIO').reset_index()
del df['ISCONVERTED']

【讨论】：

抱歉：我已经测试过这段代码，但它只提供了部分结果，即当 ISCONVERTED = 1 时，而不是当 ISCONVERTED = 0 时的其余结果
好的，我误解了您要查找的内容（因为 ISCONVERTED = 0 定义为 1 - (ISCONVERTED = 1)。
当我像在我的代码中那样尝试你的第二段代码时，我有这个错误：ValueError: cannot insert ISCONVERTED, already exists
你是对的。我会最后编辑一个。问题是系列名称（IS_CONVERTED）也是索引之一的名称。
太棒了，现在它可以与新列 RATIO 一起使用，就像您在代码中所做的那样。解决方案：重置索引+创建一个新列，谢谢；）

【解决方案2】：

你可以尝试这样做：

df = df.groupby(['CREATEDDATE'])['ISCONVERTED'].value_counts(normalize = True).unstack(fill_value=0)

df = pd.DataFrame(df.to_records())
df = df.melt(id_vars=['CREATEDDATE']).sort_values(by='CREATEDDATE', ascending=True).reset_index(drop=True)
df = df.rename(columns={'variable':'VALUE', 'value':'PERCENTAGE'})

输出：

        CREATEDDATE   VALUE  PERCENTAGE
0     01 January 21     0        0.00
1     01 January 21     1        1.00

5       03 March 21     1        0.70
6       04 April 21     0        1.00
7       04 April 21     1        0.00
8         05 May 21     0        1.00
9         05 May 21     1        0.00
10       06 June 21     0        0.50

13       07 July 21     1        0.00
14     08 August 20     1        1.00
15     08 August 20     0        0.00
