python pandas 使用 "title" 将逗号分隔值放入列中

Question

我在同一列中有一些 comma-separated 数据，我希望将每个值分成不同的列。

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

我用下面的方法做了分离

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（必须为每一列提供一些标题）

    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']

python pandas 使用 "title" 将逗号分隔值放入列中

python pandas give comma separated values into columns with "title"
