你好，为什么当我使用相对路径时文件exists（）返回False，但当路径是绝对路径时返回True？谢谢

Question

import pathlib

home1 =pathlib.Path("/Users/sergii/Desktop/hello.txt")
print(f"home 1 is located {home1.cwd()}")  #home 1 is located /Users/sergii/Documents
print(f"home 1 exists {home1.exists()}")   #home 1 exists True
print(f"home 1 is a file {home1.is_file()}\n")


home2 = pathlib.Path("Desktop/hello.txt")
print(f"home 2 is located {home2.cwd()}")  #home 2 is located /Users/sergii/Documents
print(f"home 2 exists {home2.exists()}")   #home 2 exists False
print(f"home 2 is a file {home2.is_file()}")

Answer 1

您的第二个示例是解析相对于当前工作目录的相对路径 Desktop/hello.txt，因此它正在检查 /Users/sergii/Documents/Desktop/hello.txt 是否存在。
