# Python Evaluation

#######################################################################################################################
#
#   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
