如何使用 UliEngineering 在 Python 中从 NumPy datetime64 数组提取月份
你可以使用 UliEngineering Python 库轻松从 NumPy datetime64 数组中提取月份分量：
extract_months.py
import numpy as np
from UliEngineering.Utils.Date import *
# 创建 datetime64 数组
dates = np.array(['2024-01-15', '2024-06-20', '2024-12-31'], dtype='datetime64[D]')
# 提取月份
months = extract_months(dates)
print(f"Dates: {dates}")
print(f"Months: {months}")示例输出
extract_months_output.txt
Dates: ['2024-01-15' '2024-06-20' '2024-12-31']
Months: [ 1 6 12]extract_months() 函数返回一个 NumPy 数组，包含输入数组中每个 datetime64 值对应的月份（1-12）。
