How Can I Dynamically Assign Variable Names in Python?

Using Dynamic Variable Names: Assigning a Variable Based on a String

In Python, you can dynamically assign variable names based on string values. Consider the following scenario where you want to create a variable named after the value stored in a string variable:

foo = "bar"
foo = "something else"   # What is actually desired: bar = "something else"

To achieve this, you can utilize the exec function:

exec(foo + " = 'something else'")

In this example, foo contains the string "bar". The exec function takes a string argument and executes it as Python code. As a result, it creates a new variable named "bar" and assigns the value "something else" to it.

print(bar)  # Output: something else

It's important to note that the exec function should be used with caution, as it can execute arbitrary code and potentially lead to security vulnerabilities. In cases where you need to dynamically create variables, consider using a different approach, such as creating a dictionary and using the string value as the key to retrieve the appropriate value.
