Is there a way to print an int (score) inside of a string without getting an error?

score = 0
score = score + 1
print("Your score was ")
print(score)
print(" out of 5")

That is the code i currently have, which prints

Output:Your score was
1
out of 5

And when i change it to this

score = 0
score = score + 1
print("Your score was " + score + " out of 5")

I get the error

Error:Traceback (most recent call last):
  File "C:\Users\{USER}\Desktop\Python\game.py", line 115, in <module>
    print("Congratulations! You scored " + score + " out of 5 points")
TypeError: must be str, not int

Is there anyway to fix this? I thought about changing the score to a string in the beginning

score = "0"

But that wouldn't work because when you get a question right, and use

score = score + 1

You would get an error. Unless you use

score = score + "1"

But then score would equal to "01" and not "1"

Please read the docs about strings... specially the format and the f-strings.
As a summary there are 4 methods to create strings with the value of a variable in it:

Using str:

print("Your score was " + str(score) + " out of 5")

You have no control of the format used

Using the old % syntax:

print("Your score was %d out of 5" % score)
# Or, for more than 1 variable
print("Your score was %d out of %d" % (score, 5))

You control the format and is easy for 1 or 2 variables...

The format command:

print("Your score was {} out of 5".format(score))
# but can be something complex as:
print("Your score was {:{w}d} out of {}".format(score, 5, w=3))

Much versatile than the %-formatting, more complex, also.

f-strings, only for python3.6+

print(f"Your score was {score} out of 5")
# Accept almost anything you can do with format
w = 3
print(f"Your score was {score:{w}d} out of 5")

For me the cleanest option to format strings...

There are a few more (strings.Template) but with this 4 options you cover the 99% of the cases.

>>> score = 0
>>> score += 1
>>> print("Your score was {} out of 5".format(score))
Your score was 1 out of 5
>>>
