Question

I have to write a script that does this:

Inputfile:
Name
10
-43
54
Name2
654
43
2
-5467
Name3
65
65

Outputfile:
Name 21
Name2 -4768
Name3 130

I came to the conclusion that I am supposed to split the input into arrays at the names and then print the first element and the sum of the rest, but I do not know how to do it and I haven’t really found anything about this on the web.

Answer 1

Some hints:

>>> int('Name1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'Name1'
>>> int('-43')
-43

That should help you figure out what is a string and what not. It will also convert your input to a number for you.

Find out how to catch errors (try, except).

Find out how to read a file line by line. Try iterating over the file 😉

The rest is basic programming logic. Figuring it out yourself will give you most bang for the buck.
