Hello! My name is William and im 14 years old and live in sweden. Im pretty
new to programing in python and i need some help with code, (That’s why i’m
here). But i couldn’t really find what i was searching for on the internet. I’m
trying to write code that can check only the first line in a .txt file and
check if it’s the same as the int 1000. I preferably want it to be an if
satement but anything works, i just don’t know how i should write it. I’ve been
browsing the internet for a solution but sadly can’t seem to find a solution to
it.
I don’t really know if this is the right way to get help or even if this email
is for something else. Hopefully i will get some kind of response.
Best regards, William
It won't be; it can't be. A text file contains only text. The line you read
from it might be the string '1000' (or more likely '1000\n', which is 4 digits
followed by a newline character), but it cannot be the int 1000 because data has
types.
str(1000) gives you '1000', because ints can be converted to strings.
int('1000') gives you 1000 because and strings consisting only of digits can be
converted to ints. So the two types are convertible into one another. But
that's a thing you need to do explicitly. If x is a thing you just read from a
text file then
if x == 1000:
can never be true.
