locals() returns a dictionary of present local symbol table in Python

locals() returns a dictionary of symbol table in local name space

global() is same as using locals() in global name space ( or module level )

print(locals())

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(locals()['my_var']) # plus2net

locals() within a class

class student_kit():
    college_name='ABC College'  #class attributes

     #instance attributes
    def __init__(self,name,section):
        self.name= name
        self.section=section
        self.height=5  #instance attribute
        print(locals())

Alex=student_kit('Alex','A')

Output is here

{'self': <__main__.student_kit object at 0x000002A8DD23B5F8>,
 'name': 'Alex', 'section': 'A'}

Using User defined function

def student_kit():
    my_var='plus2net'
    print(locals()['my_var'])  # plus2net
    locals()['my_var']='Welcome'
    print(my_var)              # plus2net
student_kit()

Output

plus2net
plus2net

Note that the value of variable my_var is not changed.
