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

I am trying to write a text game and I have run into an error in the function I am defining that lets you basically spend your skill points after you make your character. At first, the error stated that I was attempting to subtract a string from an integer in this part of the code:

balance - strength
. Obviously that was wrong so I fixed it with
strength = int(strength)
... but now I am getting this error which I have never seen before(new programmer) and I am stumped on what exactly it is trying to tell me and how I fix it.

Here is my code for the part of the function that isn't working:

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 here is the error I get when I get to this part of the code in the shell:

Your SP balance is currently 25.
How much SP do you want to put into strength?5

Does anyone know how to solve this? Thanks ahead.

Answer

You cannot concatenate a string with an int. You would need to convert your int to string using str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

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

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")
