如何将 'O' 值转换为日期格式

Question

我尝试转换具有 'O' 值的列，如

31 October 2020
31 October 2020
31 October 2020
30 November 2020
30 November 2020

日期格式：

df['Date']=pd.to_datetime(df['Date'], errors='coerce', format='%m %d %Y')

但是我得到了 NaT 值，而不是 10/31/2020 和 11/30/2020。使用代码后，类型为dtype('<M8[ns]').

你能解释一下错误在哪里吗？

Answer 1

尝试：

import pandas as pd
from io import StringIO

inputtxt = StringIO("""Date
31 October 2020
31 October 2020
31 October 2020
30 November 2020
30 November 2020""")

df = pd.read_csv(inputtxt)
df['Date2'] = pd.to_datetime(df['Date'], format='%d %B %Y').dt.strftime('%m/%d/%Y')
print(df)

输出：

               Date       Date2
0   31 October 2020  10/31/2020
1   31 October 2020  10/31/2020
2   31 October 2020  10/31/2020
3  30 November 2020  11/30/2020
4  30 November 2020  11/30/2020
