I already searched for answers and read some links, but didn't understand. Can anyone give a simple explanation?

Both functions use the os.path.split(path)function to split the pathname pathinto a pair; (head, tail).
两个函数都使用该os.path.split(path)函数将路径名拆分path为一对；(head, tail).
The os.path.dirname(path)function returns the head of the path.
该os.path.dirname(path)函数返回路径的头部。
E.g.: The dirname of '/foo/bar/item'is '/foo/bar'.
例如： 的目录名'/foo/bar/item'是'/foo/bar'。
The os.path.basename(path)function returns the tail of the path.
该os.path.basename(path)函数返回路径的尾部。
E.g.: The basename of '/foo/bar/item'returns 'item'
例如：'/foo/bar/item'返回的基本名称'item'

To summarize what was mentioned by Breno above
总结上面 Breno 提到的内容
Say you have a variable with a path to a file
假设您有一个带有文件路径的变量
path = '/home/User/Desktop/myfile.py'
os.path.basename(path)returns the string 'myfile.py'
os.path.basename(path)返回字符串 'myfile.py'
and
和
os.path.dirname(path)returns the string '/home/User/Desktop'(without a trailing slash '/')
os.path.dirname(path)返回字符串'/home/User/Desktop'（没有尾部斜杠'/'）
These functions are used when you have to get the filename/directory name given a full path name.
当您必须获取给定完整路径名的文件名/目录名时，将使用这些函数。
In case the file path is just the file name (e.g. instead of path = '/home/User/Desktop/myfile.py'you just have myfile.py), os.path.dirname(path)returns an empty string.
如果文件路径只是文件名（例如，而不是path = '/home/User/Desktop/myfile.py'您只有myfile.py），则os.path.dirname(path)返回一个空字符串。
