Create dictionary where keys are variable names

Question

I quite regularly want to create a dictionary where keys are variable names. For example if I have variables a and b I want to generate: {\"a

Answer 1

Have you considered creating a class? A class can be viewed as a wrapper for a dictionary.

# Generate some variables in the workspace
a = 9; b = ["hello", "world"]; c = (True, False)

# Define a new class and instantiate
class NewClass(object): pass
mydict = NewClass()

# Set attributes of the new class
mydict.a = a
mydict.b = b
mydict.c = c

# Print the dict form of the class
mydict.__dict__
{'a': 9, 'b': ['hello', 'world'], 'c': (True, False)}

Or you could use the setattr function if you wanted to pass a list of variable names:

mydict = NewClass()
vars = ['a', 'b', 'c']
for v in vars: 
    setattr(mydict, v, eval(v)) 

mydict.__dict__
{'a': 9, 'b': ['hello', 'world'], 'c': (True, False)}
