Generate Python variables dynamically

[deanhystad]

If you have an object you can set attributes for the object

import junk

for name, value in zip('abc', (1, 2, 3)):
    setattr(junk, name, value)

print(junk.a, junk.b, junk.c)

Output:
1 2 3

What I don't know is how to get the module for the file you are in. I suppose you could use locals() or globals().

globals()['a'] = "I am a global a"
locals()['b'] = "I am a global b"

def func():
    locals()['b'] = "I am local b"
    locals()['c'] = "I am local c"
    print(a)
    print(b)
    print(c)

print(a)
print(b)

func()

Output:
I am a global a
I am a global b
I am a global a
I am a global b
Traceback (most recent call last):
  File "...", line 14, in <module>
    func()
  File "...", line 9, in func
    print(c)
NameError: name 'c' is not defined

Looks like locals() doesn't create variables in the local scope of the function. Not surprising.

I cannot fathom why you would ever want to do this. A variable is a convenient name you can use to access an object. Dynamically created names are not going to be convenient.
