如何在python中从NetCDF文件中拆分数据信息(YYYMMDD) ino YYYY MM DD？

import netCDF4 as nc
from datetime import datetime

dataset = nc.Dataset('filename.nc', 'r')  # 替换'filename.nc'为实际的文件路径

time_var = dataset.variables['time']  # 假设时间变量名为'time'
times = nc.num2date(time_var[:], time_var.units)

dates = [datetime.strftime(date, '%Y %m %d') for date in times]

import netCDF4 as nc
from datetime import datetime

def split_date(date):
    return datetime.strftime(date, '%Y %m %d')

def split_dates_from_netcdf(filename):
    dataset = nc.Dataset(filename, 'r')
    time_var = dataset.variables['time']  # 假设时间变量名为'time'
    times = nc.num2date(time_var[:], time_var.units)
    dates = [split_date(date) for date in times]
    dataset.close()
    return dates

filename = 'filename.nc'  # 替换为实际的文件路径
dates = split_dates_from_netcdf(filename)
print(dates)
