Python os.path.getatime()

Python中的os.path.getatime()方法用于获取指定路径的最后一次访问时间。此方法返回一个浮点值，表示自epoch以来的秒数。如果文件不存在或无法访问，此方法将引发OSError异常。

注意:epoch表示时间开始的点。它是平台相关的。对于Unix, epoch是1970年1月1日00:00:00 (UTC)。

语法:os.path.getatime(path)

参数:

path:表示文件系统路径的类路径对象。类路径对象是表示路径的字符串或字节对象。

返回类型:此方法返回类“float”的浮点值，该值表示指定路径的最后一次访问时间(以秒为单位)。

示例1

使用os.path.getatime()方法

# Python program to explain os.path.getatime() method 
    
# importing os and time module 
import os
import time
  
# Path
path = '/home/User/Documents/file.txt'
  
# Get the time of last
# access of the specified
# path since the epoch
access_time = os.path.getatime(path)
print("Last access time since the epoch:", access_time)
  
# convert the time in
# seconds since epoch
# to local time
local_time = time.ctime(access_time)
print("Last access time(Local time):", local_time)

输出:

Last access time since the epoch: 1558447897.0442736
Last access time (Local time): Tue May 21 19:41:37 2019

使用os.path.getatime()方法时的错误处理

# Python program to explain os.path.getatime() method 
    
# importing os, time and sys module 
import os
import sys
import time
  
# Path
path = '/home/User/Documents/file2.txt'
  
# Get the time of last
# access of the specified
# path since the epoch
try:
    access_time = os.path.getatime(path)
    print("Last access time since the epoch:", access_time)
  
except OSError:
    print("Path '%s' does not exists or is inaccessible" %path)
    sys.exit()
  
# convert the time in
# seconds since epoch
# to local time
local_time = time.ctime(access_time)
print("Last access time(Local time):", local_time)
  
  
# above code will print
# 'File does not exists or is inaccessible'
# if the specified path does not
# exists or is inaccessible
  

输出:

Path '/home/User/Documents/file2.txt' does not exists or is inaccessible
