Question

我找不到此日期时间的正确格式。我尝试了几种格式，dd($image)是我在下面的示例中可以找到的最接近的格式。

Illuminate\Http\UploadedFile {#270 ▼
  -test: false
  -originalName: "korabl_more_zakat_luna_63381_1920x1080.jpg"
  -mimeType: "image/jpeg"
  -error: 0
  #hashName: null
  path: "/tmp"
  filename: "phpfJOzTp"
  basename: "phpfJOzTp"
  pathname: "/tmp/phpfJOzTp"
  extension: ""
  realPath: "/tmp/phpfJOzTp"
  aTime: 2020-02-07 18:51:11
  mTime: 2020-02-07 18:51:11
  cTime: 2020-02-07 18:51:11
  inode: 34603072
  size: 425567
  perms: 0100600
  owner: 1000
  group: 1000
  type: "file"
  writable: true
  readable: true
  executable: false
  file: true
  dir: false
  link: false
}

结果：

%Y/%m/%d%I:%M:%S%p

Answer 1

您可以使用参数infer_datetime_format=True解决此问题。这是一个示例：

df = {}
df['datetime'] = '2019-11-13 16:28:05.779'
df['datetime'] = pd.to_datetime(df['datetime'], infer_datetime_format=True)
print(df['datetime'])
print(type(df['datetime'])

输出：

2019-11-13 16:28:05.779000
<class 'pandas._libs.tslibs.timestamps.Timestamp'>

Answer 2

在猜测自己有大熊猫之前，请先进行猜测

df['datetime'] = pd.to_datetime(df['datetime'], infer_datetime_format=True)
0   2019-11-13 16:28:05.779
Name: datetime, dtype: datetime64[ns]

Answer 3

以下是带有正确格式字符串的pandas.to_datetime()调用：pd.to_datetime(df['datetime'], format="%Y/%m/%d %H:%M:%S")

您错过了一个空格，%I停留了12个小时（示例时间为16:28，而%p引用了等效于AM或PM的语言环境。

如何以所需的方式在数据框中格式化日期时间？
