Put this line "fclose(fid); "matlab code translates into python code

In Python, there is no direct equivalent of the `fclose` function in MATLAB since Python's file handling is different. To close a file in Python, you can use the `close()` method of the file object. Here's an example:

# Open a file
myfile = open("filename.txt", "r")

# ... do some operations on the file ...

# Close the file
myfile.close()

So the equivalent of `fclose(fid);` in Python would be:

fid.close()
