Python os.path.isabs()

Python中的os.path.isabs()方法用于检查指定的路径是否为绝对路径。

在Unix平台上，绝对路径以正斜杠(‘ / ‘)开始，而在Windows上，删除任何可能的驱动器号后，绝对路径以反斜杠(‘ \ ‘)开始。

语法:os.path.isabs(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:此方法返回一个类bool的布尔值。如果指定的路径是绝对路径，此方法返回True，否则返回False。

示例1

使用os.path.isabs()方法(在Unix平台上)

# Python program to explain os.path.isabs() method 
    
# importing os.path module 
import os.path
  
# Path
path = '/home/User/Documents'
  
# Check whether the 
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)
  
  
# Path
path = 'home/User/Documents/'
  
# Check whether the 
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)
  
  
# Path
path = '../User/Documents/'
  
# Check whether the 
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)

输出:

True
False
False

示例2

使用os.path.isabs()方法(在Windows上)

# Python program to explain os.path.isabs() method 
    
# importing os.path module 
import os.path
  
# Path
path = r"C:\\Users\\Documents"
  
# Check whether the 
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)
  
  
# Path
path = r"\\User\\Documents"
  
# Check whether the 
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)
  
  
# Path
path = r"User\\Documents"
  
# Check whether the 
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)
