os.listdir(path)[0][:-7]

This code returns the first file name in the directory specified by the path variable, without the last 7 characters of the file name.
For example, if the first file in the directory is "example_file_2021.txt", the code would return "example_file".
Here's a breakdown of the code:
- os: This is a module in Python that provides a way to interact with the operating system.
- listdir(path): This function returns a list of all files and directories in the directory specified by the path variable.
- [0]: This selects the first item in the list returned by listdir.
- [:-7]: This slices the string to remove the last 7 characters from the file name.
Note that this code assumes that the first item in the directory is a file (not a directory), and that the file name has at least 7 characters. If these assumptions are not met, the code may raise an error.
