interpreter.py

# In a file called interpreter.py, implement a program that prompts the user for an arithmetic expression
# and then calculates and outputs the result as a floating-point value formatted to one decimal place.
# Assume that the user’s input will be formatted as x y z, with one space between x and y and one space between y and z, wherein:

# x is an integer
# y is +, -, *, or /
# z is an integer
# For instance, if the user inputs 1 + 1, your program should output 2.0. Assume that, if y is /, then z will not be 0.

# Note that, just as python itself is an interpreter for Python, so will your interpreter.py be an interpreter for math!

expression = str(input("Expression: ")).strip()

x, y, z = expression.split(" ")
x = int(x)
z = int(z)

if y == "+":
    print(float(x + z))
elif y == "-":
    print(float(x - z))
elif y == "*":
    print(float(x * z))
elif y == "/":
    print(float(x / z))
