Solve the programming task below in a Python markdown code block.
The eval() expression is a very powerful built-in function of Python. It helps in evaluating an expression. The expression can be a Python statement, or a code object.  

For example:  

>>> eval("9 + 5")
14
>>> x = 2
>>> eval("x + 3")
5

Here, eval() can also be used to work with Python keywords or defined functions and variables. These would normally be stored as strings.  

For example:

>>> type(eval("len"))
<type 'builtin_function_or_method'>

Without eval()

>>> type("len")
<type 'str'>

Task 

You are given an expression in a line. Read that line as a string variable, such as var, and print the result using eval(var).  

NOTE: Python2 users, please import from __future__ import print_function.  

Constraint 

Input string is less than 100 characters.  

Sample Input  

print(2 + 3)

Sample Output  

5
