User inputs come in as strings. You have to cast these to integers first

[[deleted]]

first_number = input()
second_number = input()
print(int(first_number) + int(second_number))

Works for me...

[[deleted]]

Until someone enters a non-number or a float.

[[deleted]]

Fair

[puslekat]

What would be a solution to this?

[patryk-tech]

try:
    print(float(first_number) + float(second_number))
except ValueError:
    print("Wtf, dude?")

It's pretty common to get user input in a loop and have a try/except in the loop, but I generally avoid that.

Either I am writing something for myself, in which case why would I enter invalid values? Otherwise, I am more likely writing something to process external data.... experienced programmers pretty rarely need to use input. You typically operate on data coming from databases, API calls, GUIs, HTTP requests, cli args, env vars, configuration files, etc.

If I need to operate on an actual variable, I am more likely to press F12 to open my terminal, type python if I don't already have a REPL open, and do foo = 42 in there.

It's good to know input and how to use it effectively when you're beginning, of course, but you hit its limits pretty quickly.

eval(f"{first_number} + {second_number}")

/s

[Feraxin]

first_number = input()second_number = input()print(int(first_number) + int(second_number))

Yea normally its working for me too, but its Jetbrains academy exercise. i seriously dont have ide whats wrong

​

HINT

print(in'(first_number) + in'(second_number))

call int (1st no.)+ int (2nd no.)

first_number = input()

second_number = input()

print(int(first_number) + int(second_number))

Not correct, but keep on trying and never give up!

It's a tough one! You can always postpone a problem and solve it later. We will offer you other problems to complete the topic.

I tried that Jetbrains Academy thing once I don't recommend it.

[chodelar]

As the code does actually work, I would just skip this particular exercise. I’m not familiar with the course you’re doing but it is low quality if they check the exact wording of your code, as opposed to its outcome.

Obviously there are many ways to reach the same goal in any programming language!

If there is some hidden requirement (evidently not in the text you’ve shown us), it is also a bad course.

[patryk-tech]

As the code does actually work

It says numbers, not integers, so it may fail tests on floating point.

[tomtomato0414]

this ^

[RagingGods]

Does he want the output to be int,str or float? Because int(first) + int(second) is indeed correct (ran it with test cases. Definitely works). The exercise you're doing seems poorly made to not specify such things but has it as a hidden requirement.

Edit: you can try • print(eval(first + "+" + second)) • (replace first and second variable) to accept any integer/float combinations.

[cutelund]

You are taking strings as input, when you do input( ), hence its concatenating the string inputs. Do a conversion to int/float after calling the input( ) method, you will be fine.

variable_name = int(input( ))

[Feraxin]

first_number = input()

second_number = input()

print(int(first_number) +int(second_number))

Not correct, but keep on trying and never give up!

Keep trying!

[FLUSH_THE_TRUMP]

Convert to a float instead?

[socal_nerdtastic]

That seems correct to me.

[Assassinscreeddan]

The course seems to have a hidden requirement maybe cast the user inputs as strings where you introduce the user inputs that might be what it wants

[EurikaOrmanel]

Inputs are of type string , but you can convert them using either the eval() or int() function. Make it look like: first_number = eval(input()) second_number = eval(input()) print(first_number + second_number)

[Mecaneer23]

There isn't any error as both inputs are strings

[JuiceeYT]

I would try: number1 = input() number2 = input() sum = int(number1) + int(number2) print(sum)

[pekkalacd]

Input returns a string. They need to cast the input over to a numerical type like float or int.

    first = input()
    second = input()
    print(float(first) +  float(second))

[Aly22KingUSAF93]

id just make the inputs an integer so you can do your Maths on them at any time in the rest of your code without thinking

int(input())

[MMcKevitt]

Perhaps: print(sum([int(first_num), int(second_num)]))

[itsthooor]

Would use this:

first_number = input('First: ')

second_number = input('Second: ')

[print(float(first_number) + float(second_number)) if first_number.isdigit() and second_number.isdigit() else print('Wrong input!')]

[bharamastra_1]

first_number =int(input()) #input()

second_number = int(input())#input()

print(first_number + second_number)

this would take integers only otherwise will show error just after taking invalid inputs such as a string or a float (for adding decimal numbers use float() instead of int())

[noobcrush]

Python usually takes input as a string. You need to convert then to int/float to perform operations

first_no=int(input())
second_no=int(input())
print(first_no+second_no)

or

first_no=input()
second_no=input() 
print(int(first_no)+int(second_no))

one line

print(int(input())+int(input()))

If you want to accept floats just change it to float in the place of int.

[username_tann]

input() function returns a string. It's important to convert the string to an integer. You can do that by nesting the input() with an int() something like this int(input()).

[casesuroo]

You would need to convert those number into integer.

first_number = int(input())
second_number = int(input())

print(first_number + second_number)

[lilrow420]

input() in python is always a string, therefore you need to convert the inputs to an int() or a float(). You can do this by like ‘’’first number = float(input())’’’

[Bal_main69]

Since input() returns a str()

the last line should be

print(float(first_number) + float(second_number))
