Question

Help, I just cannot figure out how to make this code print "x cannot be divided by zero" after i set the y intercept value to 0 and i want the code to print "x cannot be divided by zero" everytime i put a zero for y value.

Here is my code below: (PYTHON)

x_intercept = float(input("Enter x: "))
y_intercept = float(input("Enter y: "))
operation_msg = input("Enter operation (plus, power, divide): ")
add_formula = x_intercept + y_intercept
add_final = float(add_formula)
power_formula =(x_intercept ** y_intercept)
power_final = float(power_formula)
divide_formula = x_intercept / y_intercept
divide_final = float(divide_formula)

divison_form = y_intercept
if operation_msg == "divide":
print("x divided by y is : ", divide_form)
if divison_form == 0:
print("does not work")

elif operation_msg == "plus":
print("x plus y:", add_final)

elif operation_msg == "power":
print("x to the power of y is", power_final)

else:
print ("I don't recognize that operation.")

Answer:

You should put the variables inside if else, otherwise, everytime all the operations will be performed and divide by 0 will give error.

Do it like this:

x_intercept = float(input("Enter x: "))
y_intercept = float(input("Enter y: "))
operation_msg = input("Enter operation (plus, power, divide): ")

divison_form = y_intercept
if operation_msg == "divide":
if divison_form == 0:
print("x cannot be divided by zero")
else:
divide_formula = x_intercept / y_intercept
divide_final = float(divide_formula)
print("x divided by y is : ", divide_final)
elif operation_msg == "plus":
add_formula = x_intercept + y_intercept
add_final = float(add_formula)
print("x plus y:", add_final)

elif operation_msg == "power":
power_formula =(x_intercept ** y_intercept)
power_final = float(power_formula)
print("x to the power of y is", power_final)
else:
print ("I don't recognize that operation.")
