Python locals() Function

The locals() function in Python is used to get the current local symbol table in the form of dictionary. For example:

print(locals())

The above program produces the output that looks like:

{'__name__': '__main__', '__doc__': None, '__package__': None, '__loader__': <_frozen_importlib_external.SourceFileLoader object at 0x000001CFA47A6D00>, '__spec__': None, '__annotations__': {}, '__builtins__': <module 'builtins' (built-in)>, '__file__': 'C:\\Users\\DEV\\fresherearth.com\\fresherearth.py', '__cached__': None}

Now if you execute the following code:

v = locals()
print(type(v))

then the output would be:

<class 'dict'>

means that the function locals() returns dict type object

print(x["__file__"])

The snapshot given below shows the sample output produced by this program, demonstrating the locals() function:

That is, the above Python program file is saved inside the directory C:\Users\DEV\fresherearth.com\ with its name as fresherearth.txt. But in your case, the output may be different, if you've different file name and/or directory.
