在Python中,處理復雜路徑時,可以使用os
和os.path
模塊。這些模塊提供了一系列的方法來處理文件路徑,包括拼接路徑、分割路徑、獲取當前工作目錄等。以下是一些處理復雜路徑的常用方法:
使用os.path.join()
拼接路徑:
import os
path1 = 'folder1'
path2 = 'folder2'
file_name = 'file.txt'
full_path = os.path.join(path1, path2, file_name)
print(full_path) # 輸出: folder1/folder2/file.txt
使用os.path.split()
分割路徑:
import os
full_path = 'folder1/folder2/file.txt'
path1, path2 = os.path.split(full_path)
print(path1) # 輸出: folder1/folder2
print(path2) # 輸出: file.txt
使用os.path.splitext()
分割文件名和擴展名:
import os
file_path = 'folder1/folder2/file.txt'
file_name, file_extension = os.path.splitext(file_path)
print(file_name) # 輸出: folder1/folder2/file
print(file_extension) # 輸出: .txt
使用os.path.abspath()
獲取絕對路徑:
import os
relative_path = 'folder1/folder2/file.txt'
absolute_path = os.path.abspath(relative_path)
print(absolute_path) # 輸出: /Users/username/folder1/folder2/file.txt
使用os.path.dirname()
獲取路徑中的目錄部分:
import os
file_path = 'folder1/folder2/file.txt'
directory_path = os.path.dirname(file_path)
print(directory_path) # 輸出: folder1/folder2
使用os.path.basename()
獲取路徑中的文件名部分:
import os
file_path = 'folder1/folder2/file.txt'
base_name = os.path.basename(file_path)
print(base_name) # 輸出: file.txt
使用os.getcwd()
獲取當前工作目錄:
import os
current_directory = os.getcwd()
print(current_directory) # 輸出: /Users/username/Documents (或其他當前工作目錄)
通過這些方法,可以輕松地處理復雜的文件路徑。
