Python Evaluation - HackerRank Solution
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.
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
