python pandas将逗号分隔的值放入带有“title”的列中

Question

我在同一列中有一些逗号分隔的数据，我希望将每个值分隔到不同的列中。

0          13.4119837, 42.082885, 13.4119837, 42.082885
1        11.6285463, 42.4193742, 11.6285463, 42.4193742
2            -3.606772, 39.460299, -3.606772, 39.460299
3            -0.515639, 38.988847, -0.515639, 38.988847
4            -2.403309, 37.241792, -2.403309, 37.241792

我已经使用下面进行了分离

data['column_name'].str.split(",", n = 3, expand = True)

我得到的输出是

     0           1           2           3
0   13.4119837  42.082885   13.4119837  42.082885
1   11.6285463  42.4193742  11.6285463  42.4193742
2   -3.606772   39.460299   -3.606772   39.460299
3   -0.515639   38.988847   -0.515639   38.988847
4   -2.403309   37.241792   -2.403309   37.241792

但我需要类似下面的内容（必须为每列提供一些标题）

    minLat      maxLat       minLong     maxLong
0   13.4119837  42.082885   13.4119837  42.082885
1   11.6285463  42.4193742  11.6285463  42.4193742
2   -3.606772   39.460299   -3.606772   39.460299
3   -0.515639   38.988847   -0.515639   38.988847
4   -2.403309   37.241792   -2.403309   37.241792

我该怎么做？

Answer 1

使用df.columns:

data = data['column_name'].str.split(",", n = 3, expand = True)
data.columns = ['minLat', 'maxLat', 'minLong', 'maxLong']
