Converting between datetime, Timestamp and datetime64 in python

Converting between datetime, Timestamp and datetime64 in python

In Python, you can convert between datetime, Timestamp, and datetime64 objects using various libraries, such as datetime, pandas, and numpy. Below are examples of how to perform these conversions:

  • Convert datetime to Timestamp (Pandas):
import pandas as pd from datetime import datetime # Create a datetime object dt = datetime(2023, 9, 18, 12, 0, 0) # Convert to Timestamp ts = pd.Timestamp(dt) # Print the Timestamp print(ts)
  • Convert datetime64 to datetime (Numpy):
import numpy as np from datetime import datetime # Create a datetime64 object dt64 = np.datetime64('2023-09-18T12:00:00') # Convert to datetime dt = dt64.astype(datetime) # Print the datetime print(dt)
  • Convert Timestamp to datetime (Pandas):
import pandas as pd # Create a Timestamp object ts = pd.Timestamp('2023-09-18 12:00:00') # Convert to datetime dt = ts.to_pydatetime() # Print the datetime print(dt)
  • Convert datetime to datetime64 (Numpy):
import numpy as np from datetime import datetime # Create a datetime object dt = datetime(2023, 9, 18, 12, 0, 0) # Convert to datetime64 dt64 = np.datetime64(dt) # Print the datetime64 print(dt64)

These examples demonstrate how to convert between these datetime representations using Python libraries like datetime, pandas, and numpy. Depending on your specific needs and the libraries you are working with, you can choose the appropriate method for conversion.

Examples

  1. Convert datetime to Timestamp in Python Description: This query explores methods to convert a Python datetime object to a Pandas Timestamp, facilitating seamless integration of datetime data with Pandas DataFrame indexing and manipulation.

    import datetime import pandas as pd dt = datetime.datetime(2024, 3, 21, 8, 30, 0) timestamp = pd.Timestamp(dt) print(timestamp)

  2. Convert Timestamp to datetime in Python Description: This query seeks techniques to convert a Pandas Timestamp object back to a Python datetime object, enabling compatibility with libraries and functions that require datetime data.

    import pandas as pd timestamp = pd.Timestamp('2024-03-21 08:30:00') dt = timestamp.to_pydatetime() print(dt)

  3. Convert datetime to datetime64 in Python Description: This query aims to convert a Python datetime object to the datetime64 data type in NumPy, facilitating efficient storage and manipulation of datetime data in numerical computations.

    import datetime import numpy as np dt = datetime.datetime(2024, 3, 21, 8, 30, 0) dt64 = np.datetime64(dt) print(dt64)

  4. Convert datetime64 to datetime in Python Description: This query is about converting a datetime64 object from NumPy back to a Python datetime object, enabling compatibility with libraries and functions that require datetime data.

    import numpy as np dt64 = np.datetime64('2024-03-21T08:30:00') dt = dt64.astype(datetime.datetime) print(dt)

  5. Convert Timestamp to datetime64 in Python Description: This query seeks methods to convert a Pandas Timestamp object to the datetime64 data type in NumPy, enabling interoperability with NumPy and Pandas datetime data.

    import pandas as pd import numpy as np timestamp = pd.Timestamp('2024-03-21 08:30:00') dt64 = np.datetime64(timestamp) print(dt64)

  6. Convert datetime64 to Timestamp in Python Description: This query explores techniques to convert a datetime64 object from NumPy to a Pandas Timestamp object, enabling seamless integration of datetime data between NumPy and Pandas.

    import pandas as pd import numpy as np dt64 = np.datetime64('2024-03-21T08:30:00') timestamp = pd.Timestamp(dt64) print(timestamp)

  7. Convert datetime64 to datetime string in Python Description: This query aims to convert a datetime64 object from NumPy to a string representation of datetime in Python, suitable for various display and storage purposes.

    import numpy as np dt64 = np.datetime64('2024-03-21T08:30:00') dt_str = str(dt64) print(dt_str)

  8. Convert datetime string to datetime64 in Python Description: This query is about converting a string representing a datetime to the datetime64 data type in NumPy, enabling efficient storage and manipulation of datetime data in numerical computations.

    import numpy as np dt_str = '2024-03-21T08:30:00' dt64 = np.datetime64(dt_str) print(dt64)

  9. Convert datetime to datetime64 with timezone Description: This query seeks methods to convert a Python datetime object to the datetime64 data type in NumPy with timezone information, enabling accurate representation of time zones.

    import datetime import numpy as np dt = datetime.datetime(2024, 3, 21, 8, 30, 0, tzinfo=datetime.timezone.utc) dt64 = np.datetime64(dt) print(dt64)

  10. Convert datetime64 to custom formatted string Description: This query aims to convert a datetime64 object from NumPy to a custom formatted string representation, allowing users to specify the desired output format.

    import numpy as np dt64 = np.datetime64('2024-03-21T08:30:00') custom_formatted_str = np.datetime_as_string(dt64, unit='s') print(custom_formatted_str)
