[Numpy] Load date/time from .txt to 'datetime64' type.

[Gribouillis]

That seems a good method for this case, thanks.

You can skip a double conversion by creating the array with numpy.fromiter()

import datetime as dt
import io
import numpy as np

file = io.StringIO(
    """\
2024-2-27, 0:0:0
2024-2-27, 3:7:2
2024-2-27, 4:11:3
2024-2-27, 6:3:5
2024-2-27, 13:10:6
2024-2-27, 20:20:7
2024-2-27, 21:30:9
2024-2-27, 22:40:10
2024-2-27, 23:50:12
"""
)


def parse(line):
    return dt.datetime.strptime(line, "%Y-%m-%d, %H:%M:%S\n")


a = np.fromiter((parse(line) for line in file), dtype="datetime64[s]")

print(a)
