'''
Your task is to create a function that does four basic mathematical operations.

The function should take three arguments - operation(string/char), value1(number), value2(number).
The function should return result of numbers after applying the chosen operation.

Examples:

basic_op('+', 4, 7)         # Output: 11
basic_op('-', 15, 18)       # Output: -3
basic_op('*', 5, 5)         # Output: 25
basic_op('/', 49, 7)        # Output: 7
'''

def basic_op(operator, value1, value2):
    #your code here
    if operator=='+':
        return value1+value2
    elif operator=='-':
        return value1-value2
    elif operator=='*':
        return value1*value2
    else:
        return value1/value2
