globals() returns a dictionary of present global symbol table in Python

globals()

globals() returns a dictionary of symbol table in global name space

globals() is same as using locals() in global name space

print(globals())

This will return a dictionary, some sample elements are shown here.

{'__name__': '__main__', '__doc__': 'Automatically created module for IPython interactive environment', '__package__': None, '__loader__': None, '__spec__': None ........
.........}

We can print any element by using key

my_var='plus2net'
print(globals()['my_var']) # plus2net

Default global variables

a=globals()
print(a['__name__'])
print(a['_dh'])

Using User defined function

x=5
def my_sum():
   a=8
   x=10 # local variable
print(globals()['x'])   # 5 
# print(globals()['a']) # KeyError

The last line will return KeyError as the variable a is not available in global name space.
