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.
>>> eval("9 + 5")
>>> x = 2
>>> eval("x + 3")
Here, eval() can also be used to work with Python keywords or defined functions and variables. These would normally be stored as strings.
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.
from __future__ import print_function
Input string is less than 100 characters.
print(2 + 3)
