I have always loved the fact that The Python interpreter has a number of functions and types built into it. I am going to explore “eval()” in this article.

Syntax: eval(<em>expression</em>[, <em>globals</em>[, <em>locals</em>]])
or
eval(expr, globals=None, locals=None)

So, mainly eval need string as its argument in expression.

<td>
  Global namespace to use while executing the source. It must be a dictionary. If not provided then the current global namespace will be used.
</td>

<td>
  Local namespace to use while executing the source. It can be any mapping. If omitted, it defaults to&nbsp;<code>globals</code>&nbsp;dictionary.
</td>

You can check globals and locals by global() and locals().

Example

The output will be –

Isn’t it cool? 🙂
