Python| os.remove() 方法

Python中的OS 模块提供了与操作系统交互的功能。操作系统属于 Python 的标准实用程序模块。该模块提供了一种使用操作系统相关功能的可移植方式。

os 模块中的所有函数在文件名和路径无效或不可访问的情况下，或具有正确类型但操作系统不接受的其他参数的情况下引发OSError 。

Python中的os.remove()方法用于删除或删除文件路径。此方法不能删除或删除目录。如果指定的路径是目录，则该方法将引发OSError 。 os.rmdir()可用于删除目录。

Syntax: os.remove(path, *, dir_fd = None)

Parameter:
path: A path-like object representing a file path. A path-like object is either a string or bytes object representing a path.
dir_fd (optional) : A file descriptor referring to a directory. The default value of this parameter is None.
If the specified path is absolute then dir_fd is ignored.

Note: The ‘*’ in parameter list indicates that all following parameters (Here in our case ‘dir_fd’) are keyword-only parameters and they can be provided using their name, not as positional parameter.

Return Type: This method does not return any value.

代码 #1：使用 os.remove() 方法删除文件

# Python program to explain os.remove() method 
    
# importing os module 
import os
  
# File name
file = 'file.txt'
  
# File location
location = "/home/User/Documents"
  
# Path
path = os.path.join(location, file)
  
# Remove the file
# 'file.txt'
os.remove(path)
print("%s has been removed successfully" %file)

输出：

file.txt has been removed successfully

代码#2：如果指定路径是目录

# Python program to explain os.remove() method 
    
# importing os module 
import os
  
# Path
path = "/home/User/Documents/ihritik"
  
# Remove the specified
# file path
os.remove(path)
print("% s has been removed successfully" % file)
  
# if the specified path 
# is a directory then 
# 'IsADirectoryError' error
# will raised 
  
# Similarly if the specified
# file path does not exists or  
# is invalid then corresponding
# OSError will be raised

输出：

Traceback (most recent call last):
  File "osremove.py", line 11, in 
    os.remove(path)
IsADirectoryError: [Errno 21] Is a directory: '/home/User/Documents/ihritik'

代码 #3：使用 os.remove() 方法时处理错误

# Python program to explain os.remove() method 
    
# importing os module 
import os
  
# path
path = '/home/User/Documents/ihritik'
  
# Remove the specified 
# file path
try:
    os.remove(path)
    print("% s removed successfully" % path)
except OSError as error:
    print(error)
    print("File path can not be removed")

输出：

[Errno 21] Is a directory: '/home/User/Documents/ihritik'
File path can not be removed
