Is it possible to create a variable with the name of an output of another variable

[Panda]

Output:
In [14]: a = 'c'

In [15]: globals()[a] = 1

In [16]: c
Out[16]: 1

In [17]: b = 'd'

In [18]: exec('{} = 10'.format(b))

In [19]: b
Out[19]: 'd'

In [20]: d
Out[20]: 10

Is this like 'put in line 16 instead of 1', or 'put in line 17'?
