How to write python codes in codechef

help
1

I tried the ATM problem of the tutorial section.
I wrote the following code.

a=int(input())
b=int(input())
if(a%5==0 and a<=b):
    print((b-a)-0.50)
else: print(b)

But an error occurred at line 1. Please guide me, how to write the input line!

What error?

Are you trying to “Run” without Providing “Custom Input”?

It’s working with custom input. But when I am submitting the code. Machine is providing the inputs in list format. That’s causing the error.

I even tried
# cook your dish here
a, b = list(map(int, input().strip().split(’ ')))
if(a%5==0 and a<=b):
print((b-a)-0.50)
else: print(b)
yet the NZEC error persists

Trying this solution with the sample test input:

30 120.00

gives the following error:

Traceback (most recent call last):
  File "./prog.py", line 2, in <module>
ValueError: invalid literal for int() with base 10: '120.00'

which is hopefully enough of a clue :slight_smile:

b==>int? are you sure

Do I need to change a, b = list(map(int, input().strip().split(’ '))) this line?

yes
chef is asking you to input 2 values

a and b are integer example(30,120)

but you have to input it as(30,120.00)

problem was solved with a, b = list(map(float, input().strip().split(’ '))).

To input two variables you don’t need to use list
you can use
a,b=map(float,input().split())
here, the split function will directly split it using spaces

I think it would not, In the question input is space separated.

yes my bad .
