Python built-in Method - globals()

In Python, globals() is a built-in function that returns a dictionary representing the global symbol table of the current module.

The global symbol table is a dictionary that stores all the global variables and functions defined in a module. When you create a variable or function in a module, it is added to the global symbol table.

The syntax for globals() is as follows:

globals()

The globals() function returns a dictionary that contains all the global variables and functions defined in the current module. The keys of the dictionary are the variable and function names, and the values are the corresponding values of the variables and functions.

Here's an example:

# module.py
x = 10
y = "Hello, world!"

def foo():
    print("This is the foo function.")

print(globals())

In the example above, we define a module called module.py. We define two global variables x and y, and a global function foo. We then call the globals() function to get the global symbol table of the module.

The output of the globals() function will be a dictionary containing the keys '__name__', '__doc__', '__package__', and so on, as well as the keys 'x', 'y', and 'foo', which represent the global variables and function defined in the module.

The globals() function is useful for debugging and introspection purposes, as it allows you to inspect the global symbol table of a module at runtime. However, modifying the global symbol table directly is generally not recommended, as it can lead to unexpected behavior and make your code harder to read and maintain.
