HackerRank Python Solution - Built-Ins - eval()

• 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).

Constraint:

• The input string is less than 100 characters.

Sample Input:

print(2 + 3)

Sample Output:

5

Solution:

exp = input()

eval(exp)
