How to create a pandas DatetimeIndex with year as frequency?

To create a Pandas DatetimeIndex with a specific frequency, such as year, you can use the pd.date_range() function. Here's how you can create a DatetimeIndex with a yearly frequency:

import pandas as pd # Create a DatetimeIndex with a yearly frequency start_year = 2020 end_year = 2025 yearly_index = pd.date_range(start=f"{start_year}-01-01", end=f"{end_year}-12-31", freq='Y') print(yearly_index)

In this example, the pd.date_range() function generates a DatetimeIndex with a yearly frequency ('Y'). You provide the start and end dates to specify the range, and the freq parameter is set to 'Y' to indicate a yearly frequency.

The resulting yearly_index will contain datetime values at the start of each year within the specified range, in this case, from 2020 to 2025.

Please note that the generated index will have a frequency of one year, and the exact datetime values will depend on the specified start and end years.

Examples

    • Code:
      import pandas as pd year = 2022 index = pd.date_range(start=f'{year}-01-01', end=f'{year}-12-31', freq='T')

  7. How to create a Pandas DatetimeIndex for a specified year with custom frequency?

    • Description: If you need a DatetimeIndex for a specific year with a custom frequency, you can adjust the freq parameter accordingly.
    • Code:
      import pandas as pd year = 2022 custom_freq = '2W' # Example custom frequency of 2 weeks index = pd.date_range(start=f'{year}-01-01', end=f'{year}-12-31', freq=custom_freq)

  8. How to generate a Pandas DatetimeIndex for a given year with second frequency?

    • Description: Generating a DatetimeIndex for a particular year with a frequency of one second can be useful for fine-grained time analysis.
    • Code:
      import pandas as pd year = 2022 index = pd.date_range(start=f'{year}-01-01', end=f'{year}-12-31', freq='S')
