在Python中,可以使用osos.path模块来处理和转换路径。以下是一些常用的方法:

  1. 获取当前工作目录:
import os
current_directory = os.getcwd()
print(current_directory)
  1. 将相对路径转换为绝对路径:
import os
relative_path = "example.txt"
absolute_path = os.path.abspath(relative_path)
print(absolute_path)
  1. 将绝对路径转换为相对路径:
import os
absolute_path = "/home/user/documents/example.txt"
relative_path = os.path.relpath(absolute_path)
print(relative_path)
  1. 获取路径中的文件名和目录名:
import os
path = "/home/user/documents/example.txt"
filename = os.path.basename(path)
directory = os.path.dirname(path)
print(filename)
print(directory)
  1. 检查路径是否存在:
import os
path = "/home/user/documents/example.txt"
if os.path.exists(path):
    print("Path exists")
else:
    print("Path does not exist")
  1. 创建一个新目录:
import os
directory = "new_directory"
if not os.path.exists(directory):
    os.makedirs(directory)
  1. 遍历目录中的所有文件和子目录:
import os
path = "/home/user/documents"
for root, dirs, files in os.walk(path):
    for directory in dirs:
        print(os.path.join(root, directory))
    for file in files:
        print(os.path.join(root, file))

这些方法可以帮助你在Python中处理和转换路径。根据实际需求,你可以选择合适的方法来实现路径操作。
