In this post we will be creating a Python script that will retrieve the value of a string expression. To do this we will use the built in ‘eval()’ function which parses and evaluates a string expression as a Python expression.
See below our string for this example.
expression = "3+5"See the snippet of Python code below that will retrieve the value of our string expression using the ‘eval()’ function.
expression = "3+5"
print(eval(expression))
The above would return the following as output.
