Python os.DirEntry.name属性

Python os模块的os.scandir()方法产生os.DirEntry对象，对应于指定路径给出的目录中的条目。os.DirEntry对象具有各种属性和方法，用于公开目录项的文件路径和其他文件属性。

os.DirEntry对象上的name属性用于获取条目的基本文件名，相对于os.scandir()方法中使用的path参数。

注意:os.DirEntry对象的目的是在迭代后被使用和扔掉，因为对象的属性和方法缓存了它们的值，再也不会重新获取值。如果文件的元数据已经被更改，或者如果自调用os.scandir()方法以来已经经过了很长时间。我们将得不到最新的信息。

os.DirEntry.name 语法

os.DirEntry.name 

os.DirEntry.name 参数

返回值:该属性返回一个表示条目基本文件名的字符串值。

os.DirEntry.name 示例1

使用os.DirEntry.name属性

# Python program to explain os.DirEntry.name attribute 
  
# importing os module  
import os
  
  
# Directory to be scanned
# Current working directory
path = os.getcwd()
  
# Using os.scandir() method
# scan the specified directory
# and yield os.DirEntry object
# for each file and sub-directory
  
print("Base filename of all directory entry in '% s':" % path) 
with os.scandir(path) as itr:
    for entry in itr :
        # Exclude the entry name
        # starting with '.'  
        if not entry.name.startswith('.') :
            # print entry's name 
            print(entry.name)

输出:

Base filename of all directory entry in '/home/ihritik':

使用os.DirEntry.name()属性

# Python program to explain os.DirEntry.name attribute 
  
# importing os module  
import os
  
# Directory to be scanned
# Current working directory
path = os.getcwd()
  
# Using os.scandir() method

print("All files and directory whose name starts with letter 'D' in '% s'" % path) 
with os.scandir(path) as itr:
    for entry in itr :
        # Check if directory entry name
        # starts with letter 'D'
        if entry.name.startswith('D') :
            # print entry's name 
            print(entry.name)
