Keep getting error when using += operation between two variables - Python

I currently have a bit of code that adds a certain amount of points to a plyers score:

points = 5
player1 = 0
float(points)
float(player1)
player1 += points
points = 0

The problem is when I run this I get this error:

TypeError: unsupported operand type(s) for +=: 'int' and 'str'

At first, I thought it had to do with the data types of the variables, points and player1 but I have a float function right before it. Also just for debugging purposes I wrote a bool statement print(bool(float(var))) to check if it was floating correct and it wasn't. The points variable floated correctly but it was saying that player1 was not a float. Any ideas on why this is happening?

First of all, I was not able to reproduce the error, meaning I executed your code and did not get the error.

All good (using Programiz)

Second: When you cast a variable as: float(points) you must save the casting in a variable (or update the previous one).

points = float(points)

Note: in your case, you don't need to cast the variable to float because you are using only int values.

If you are reading user input, you need to assign the result of float to the variable.

points = float(points) # convert existing string, or use float(input())
player1 = float(player1)
