How Can I Create Dynamic Variables from Strings in Python?

Creating Dynamic Variables from Strings in Python

To convert a string into a variable name in Python, we need to use the exec() function. This function allows us to dynamically execute Python code at runtime.

We can use the following steps to achieve this:

1. Assign the input string to a variable: For example, x = 'buffalo'.
2. Construct the Python code to create the variable: In our case, we want to create a variable named buffalo and assign it a value. We can construct the code as follows: '%s = %d' % (x, 2), where x is the string we want to convert and 2 is the value we want to assign.
3. Execute the Python code using exec(): By using the exec() function, we can dynamically execute the code we constructed in the previous step: exec('%s = %d' % (x, 2)). This will create a variable named buffalo and assign it the value 2.

To illustrate:

Now, we can check if the variable buffalo was created by printing its value:

This should output:
