如何按工作日名称对DataFrame进行排序?我不能使用pd.to_datetime()方法,因为我的日期不是数字。
Date Transactions
0 Friday 140.652174
1 Monday 114.000000
2 Saturday 208.826087
3 Sunday 140.565217
4 Thursday 118.217391
5 Tuesday 107.826087
6 Wednesday 105.608696
最佳答案
您可以将column的值转换为ordered categoricals,因此可以使用 sort_values
:
cats = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
df['Date'] = pd.Categorical(df['Date'], categories=cats, ordered=True)
df = df.sort_values('Date')
print (df)

1 Monday 114.000000
5 Tuesday 107.826087
6 Wednesday 105.608696
4 Thursday 118.217391
0 Friday 140.652174
2 Saturday 208.826087
3 Sunday 140.565217
或按
Date
按set_index
列创建索引,然后按 reindex
和最后 reset_index
创建索引:注意:
解决方案仅在列的唯一值有效
df = df.set_index('Date').reindex(cats).reset_index()
print (df)
