在Python中获取参数中文件的目录路径

import os

# 假设这是传入的文件路径
file_path = "/home/user/documents/report.txt"

# 使用os.path.dirname获取文件的目录路径
directory_path = os.path.dirname(file_path)

print("文件的目录路径是:", directory_path)

import os

file_path = "/home/user/documents/My Report.txt"
directory_path = os.path.dirname(os.path.normpath(file_path))

print("文件的目录路径是:", directory_path)

import os

file_path = "/home/user/documents/nonexistent.txt"
if os.path.exists(file_path):
    directory_path = os.path.dirname(file_path)
    print("文件的目录路径是:", directory_path)
else:
    print("文件路径不存在")
