Python error "TypeError: Can't convert 'int' object to str implicitly"

Question

I am trying to execute the following python code

def attributeSelection():

    balance = 25

    print("Your SP balance is currently 25.")

    strength = input("How much SP do you want to put into strength?")

    strength = int(strength)

    balanceAfterStrength = balance - strength

    if balanceAfterStrength == 0:

        print("Your SP balance is now 0.")

        attributeConfirmation()

    elif strength < 0:

        print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")

        attributeSelection()

    elif strength > balance:

        print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")

        attributeSelection()

    elif balanceAfterStrength > 0 and balanceAfterStrength < 26:

        print("Ok. You're balance is now at " + balanceAfterStrength + " skill points.")

    else:

        print("That is an invalid input. Restarting attribute selection.")

        attributeSelection()

And it gives me the following error:

  Your SP balance is currently 25.

How much SP do you want to put into strength?5

TypeError: Can't convert 'int' object to str implicitly

What is the issue?

Answer 1

This is because you are concatenating string and integer. You need to convert string to integer and concat or use format method, like this:

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))
