Problem
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
.
Constraints
Input string is less than 100 characters.
Sample Input
print(2 + 3)
Sample Output
5
