我需要采用这段代码并将其转换为一个函数,该函数将从目录中.h5文件的文件名中获取信息。我对python非常陌生,因此希望我的解释有意义。下面是代码,下面是该代码需要解析的数据文件名的示例。
atl06_dir = 'ATL06 files'
filenames = glob.glob(atl06_dir + '/*h5')
year_selected = 2019
filenames_selected = list()
for filename in filenames:
product, year, month, day, hour, minute, second, track, cycle, granule, release, version = icesat2_data_utils.h5FilenameParts(os.path.basename(filename))
#need to replace this line with a function that grabs from the filename. This one does not work
if int(year) == year_selected:
filenames_selected.append(filename)
如何获得此部分以读取.h5文件的文件名,并根据名称的分隔符输出名称的不同部分,您可以在此处的示例文件名中看到该名称:
ATL06_ [yyyymmdd] [hhmmss] [ttttccss] [vvv_rr] .h5
我认为我可以要求它读取名称中的某些字符,例如:
# product ATL06 = 0 to 5
# year yyyy = indexes 8 to 12
# month mm = 12 to 14
# day dd = 14 to 16
# hour hh = 18 to 20
# minute mm = 20 to 22
# second ss = 22 to 24
# Reference ground track tttt = 27 to 31
# cycle cc = 31 to 33
# orbital segment ss = 33 to 35
# version vvv = 38 to 44
我需要采用这段代码并将其转换为一个函数,该函数将从目录中.h5文件的文件名中获取信息。我对python很陌生,所以希望我的解释在这里...
您可以根据需要将其切片,例如,
