How to hash a pandas array?

Recipe Objective

Suppose we have a code in form of string and we want to run it replacing values of variables. It can be achieved via eval function.

So this recipe is a short example on What does eval do and When can it be used. Let's get started.

Step 1 - Import the library

Let's pause and look at these imports. Pandas is generally used for performing mathematical operation and preferably over arrays.

Step 2 - Setup the Data

Here we have setup one string and assigned a constant value to a variable.

Step 3 - Calculative eval()

Simply pass the string expression into eval() function.

Step 4 - Let's look at our dataset now

Once we run the above code snippet, we will see:

120

Value of x has been simply passed into our mathematical expression for further calculation.
