How Can I Automate Dictionary Creation in Python Using Separate Variables?

Automating Dictionary Creation from Separate Variables

In Python, accessing variable names as strings is typically not straightforward. However, it becomes necessary for tasks like creating dictionaries automatically from a set of variables.

To achieve this, one approach is to iterate through the keys and values of the locals() or vars() dictionaries. By comparing the values with a specific variable, you can identify the corresponding key and assign it to a string variable.

Here's an example:

a = 1

# Iterate through local variables
for k, v in list(locals().iteritems()):
    # Check if value matches the target variable
    if v is a:
        a_as_str = k

print(a_as_str)  # Output: 'a'
print(type(a_as_str))  # Output: 'str'

This approach provides a method to retrieve variable names as strings, enabling you to create dictionaries dynamically based on the values of separate variables.
