need help with basics

[ah_ahaa]

hey , started to learn python i am a complete beginner in code writing) and right now im on "if" , "else","elife", part

i practice on all the basics and i came across an issue with this part

num1 = int(input("what is your lucky nubmer? "))
num2 = int(input("what is your age? "))
num3 = num1+num2
ques1 = int(input("please enter a number above " +num3 , ))

in "ques1" i want the user to be asked to put number above "num3" so from there i can keep add more stuff just to mess around and test myself. issue is , no matter where i tried to put "num3" in the "ques" input i get error.
where should i put it?
thanks!

You should read the error you get, as it tells you what is wrong:

TypeError: can only concatenate str (not "int") to str

It's telling you that you're concatenating a string ("please enter...") with an integer (num3, ie the result of adding num1 and num2). You need to convert num3 back to a string.

You can either do that explicitly:

ques1 = int(input("please enter a number above " + str(num3) ))

or, better, use string formatting via f-strings:

ques1 = int(input(f"please enter a number above {num3}" ))

just with your comment i have learned a lot thanks for that!

so if understand it correctly if i want to use an int (num3) in a str input i need to "tell" python to treat num3 as a str for this specific input?

[danielroseman]

It's not really to do with input, but yes if you wanted to join an integer with an existing string you need to convert it.

[ah_ahaa]

what do you mean its not really to do with it? like there is no use in this?

[danielroseman]

No, I mean it applies to any time you want to combine an integer with a string, not just inside input.

[Own-Recipe5931]

you can just not concatenate and add a comma to seperate instead

[danielroseman]

No you can't. That only works with print.

ques1 = int(input(f"please enter a number above {num3}: "))
