Why does this code not work?

Question

print('the year that you are in right now is, let me guess:' + int(input("Enter your age: ")) + int(input("Enter your birth year: ")))

Answer 1

If you're ok with having your inputs be on the line below each of your input prompts then you can add the '\n' character to your input prompt strings. It won't look the same when you run this on your computer as it will in the code playground though.

print('the year that you are in right now is, let me guess:' + str(int(input("Enter your age: \n")) + int(input("Enter your birth year: \n"))))

Answer 2

Then you'll need to wrap each input in an int function and both of them together in 1 str() function.
print('the year that you are in right now is, let me guess:' + str(int(input("Enter your age: ")) + int(input("Enter your birth year: "))))

Answer 3

Input doesn't output a newline, so the next input is printed right after it and then the print statement is. your code would probably be better if you spread it out to get the result you want.

age = int(input("Enter your age: "))
print()
year = int(input("Enter your birth year: "))
print()
print('the year that you are in right now is, let me guess:' + str(age + year))

Answer 4

I suggest you try running the code on your PC in the command line or Idle or in an IDE like PyCharm so that you can see the actual way the program would interact. The prompt for the input function is optional and can be ommitted if you wish.

Answer 5

Instead of wrapping the inputs with the int() function and then wrapping those in a str() function you can just remove the int() function entirely. input() returns a str type as it is. No need for redundant multiple conversions.

print('the year that you are in right now is, let me guess:' + input("Enter your age: ") + input("Enter your birth year: "))

Answer 6

Ah I see, wasn't aware you wanted to add them together first. Sorry about that. Didn't read it very well. lol

Answer 7

@violet, you most likely got that error because you didn't input all your inputs at the prompt in the playground. You need to input both of them at the same time on a new line like:

43
1974

This is a limitation of the code playground.

Answer 8

Personally, I would spread the code out. I'm a little OCD about the presentation to the end user and like my inputs to usually be at the end of the prompt on the same line separated by a space, but it's your code. lol

Answer 9

int(1000))+ int(1)) You don't need to wrap these int literals with the int() function. I think you want 100 not 1000 BTW. You can also skip out a pair of () parentheses if you wish.

age= input("Enter your age:")
birth_year= input("Enter your birth year:")
print("You are alive in the " + str((int(age)+int(birth_year))//100 + 1) + "st" + " century!")

Answer 10

Then you may have missed a parenthesis or something. It worked fine for me when I copied and pasted it into the playground.

Answer 11

Yep, it's the parenthesis, sorry. Thanks a lot!

One final thing: if I would want to get rid of the "Enter your age: Enter your birth year: " part of the output, are you advising me to go with separate codes as the one you have shown above?

Answer 12

Ok, but then it operates as a string, not an integer. So, for example, if I type 20 and 1997 as the input, I can't seem to get 2017. Instead, I get 201997.

There is also another problem: why can I not directly get the number I want? Meaning, why do I also get the line
Enter your age: Enter your birth year: the year that you are in right now is, let me guess:201997
as an output?

Answer 13

That made more sense at first, but nope, not working:

File "..\Playground\", line 2

^
SyntaxError: unexpected EOF while parsing

Answer 14

Alrighty, thanks! But is there no way of a compound code doing the same thing?

Answer 15

Nope, I've done that when it asked for input. That's not the problem.

Answer 16

Thinking about a typical questionnaire, the questions would be visible as to receive input, however they wouldn't be visible as a output. How do I make these two:
Enter your age:
Enter your birth year:
lines completely invisible for the output?

Is there something I don't understand about the concept?

I'm very sorry for my stubbornness and the burden I cause you, but I want to comprehend whatever I'm learning to the fullest :|

print("Thank you so much for putting up with me!")

Answer 17

Ok dok! Thank you!

Answer 18

Good idea! Thanks!

Answer 19

I have another code if you could help me out:

age= input("Enter your age:")
birth_year= input("Enter your birth year:")
print("You are alive in the " + str(((int(age)+int(birth_year))//int(1000))+ int(1))+"st" + " century!")
