检索日期介于两个日期之间的文件 [英] Retrieve files with a date between two dates

问题描述

我想从特定路径检索文件，该文件的日期介于某个开始日期和结束日期之间.

I want to retrieve files from a particular path, whose dates fall in between some start and end date.

例如:

def fetch(path, startDate, endDate):
    """
    path -> path of the directory
    startDate -> date as listed in ls (Jun 27)
    endDate -> date as listed in ls
    """

此外，我无法存储ls -lrt的输出，以检查特定的模式.

Also, I am unable to store the output of ls -lrt, so as to check for a particular pattern.

This is a function that might help you:

from datetime import datetime
from os import path
from glob import glob
from time import time as current_time

def get_files(pattern, start=0, end=None):
    """
    returns a list of all files in pattern where the files creation date is between start and end
    pattern = the pattern to retrieve files using glob
    start = the start date in seconds since the epoch (default: 0)
    end = the end date in seconds since the epoch (default: now)
    """
    start = datetime.fromtimestamp(start)
    end = datetime.fromtimestamp(current_time() if end is None else end)
    result = []
    for file_path in glob(pattern):
        if start <= datetime.fromtimestamp(path.getctime(file_path)) <= end:
            result.append(file_path)
    return result

示例:

>>> get_files('C:/Python27/*')
['C:/Python27\\DLLs', 'C:/Python27\\Doc', 'C:/Python27\\include', 'C:/Python27\\Lib', 'C:/Python27\\libs', 'C:/Python27\\LICENSE.txt', 'C:/Python27\\NEWS.txt', 'C:/Python27\\python.exe', 'C:/Python27\\pythonw.exe', 'C:/Python27\\README.txt', 'C:/Python27\\tcl', 'C:/Python27\\Tools']
