Pandas 按字母顺序对字符串列的每个值进行排序

Pandas 按字母顺序对字符串列的每个值进行排序,pandas,sorting,Pandas,Sorting,这可能很容易实现,但我还没有找到解决方案。我有一个带有字符串列“c1”的数据帧。我想按字母顺序对“c1”中的每个值进行排序。示例如下所示: dic = {'c1':['orange','box','water'],'c2':[41, 42,48]} df = pd.DataFrame.from_dict(dic) df 原始数据帧看起来像: +--------+--------+ |c1 |c2 | +--------+--------+ |orange |41

这可能很容易实现,但我还没有找到解决方案。我有一个带有字符串列“c1”的数据帧。我想按字母顺序对“c1”中的每个值进行排序。示例如下所示:

dic = {'c1':['orange','box','water'],'c2':[41, 42,48]}
df = pd.DataFrame.from_dict(dic)
df
原始数据帧看起来像:

+--------+--------+
|c1      |c2      |
+--------+--------+
|orange  |41      |
+--------+--------+
|box     |42      |
+--------+--------+
|water   |48      |
+--------+--------+
+--------+--------+
|c1      |c2      |
+--------+--------+
|aegnor  |41      |
+--------+--------+
|box     |42      |
+--------+--------+
|aertw   |48      |
+--------+--------+
我希望得到的结果如下:

+--------+--------+
|c1      |c2      |
+--------+--------+
|orange  |41      |
+--------+--------+
|box     |42      |
+--------+--------+
|water   |48      |
+--------+--------+
+--------+--------+
|c1      |c2      |
+--------+--------+
|aegnor  |41      |
+--------+--------+
|box     |42      |
+--------+--------+
|aertw   |48      |
+--------+--------+

谢谢。非常感谢。

您可以使用
应用

df['c1'] = df['c1'].apply(lambda x: ''.join(sorted(x)))
或列表理解:

df['c1'] = [''.join(sorted(x)) for x in df['c1']]
输出:

       c1  c2
0  aegnor  41
1     box  42
2   aertw  48
