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.

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. -- https://mail.python.org/mailman/listinfo/python-list

Strictly in terms of software engineering and language design, Python may well be better suited to large projects than C++ or Java. Code re-use, original coding and prototyping, unittests, and peer reviews are a lot easier with Python than with C++ or Java. The problem is that large projects tend to have portions which are performance sensitive. So a project might be 100K LOC of C with 200K LOC of Python. In my personal opinion, one can often do lowlevel performance code in a Python-ese way by using Pyrex. And it gets the additional benefit, that you pay the higher line count per feature that C forces on the developer only for the part that does this lowlevel manipulation. They serve the same purpose but are not 1:1 with a file. I personally can't think of a situation where I'd want 2 or more namespaces in a physical file, or 2 or more files per namespace. Therefore I don't see any advantage in the C++ approach. In some ways namespaces are even less flexible as Python modules. Templates address (I hesitate to say solve) static typing by adding back the polymorphism that static typing eliminates. Python avoids the fix-on-a-fix by doing dynamic strong typing in the first place. Actually C++ templates are a fix. They are one way to avoid the type system in C++. A template that takes a class argument takes any class that has all needed features and methods. Just as in Python. So it's a crazy kind of compile-time late-binding. And guess, this static typing in C++ is so sucessful, that many people consider modern C++ to be a generics oriented language, and not an OO language. Not that this is necessarily a good thing. I have to say that my Java roots do lead me to think that strong typing is a plus for big projects, since it's a way of defining and enforcing interfaces between bits of code written by different people (or by one person at different times!). Optional static typing in python would be nice for this. Java has nothing on Modula-3. Talk about strong static typing... It Well, Java got a VM. And multiple interface inheritance. And a huge standard library. M3 OTOH does have partial type revealing, which allows for more levels than private, protected and public. And even more important, M3 has the concept of safe and unsafe modules/interfaces. Safety in M3-like sense is one of the more important things in Python. If something goes wrong, in Python you usually just have to read a traceback. In C/C++ you'll get a core file if you are lucky. (Or just corrupted data) And if you are even luckier, the stack in the core file uncorrupted, and you get a sensible backtrace. In Python OTOH hand, when the traceback is not enough, one can always work with settrace and other introspection tools. IMHO languages like Python (or even Java) are a much better approach for 90% of the commercial development. There is just no rational explanation why an application developer should have to deal with memory allocation and freeing, dangling pointers, corrupted heaps, and all the other benefits that C/C++ provide. ;) used to take me 3 days to get the first compile to run on a new project. Yet after years of Modula-3 (and repeatedly seeing strong static typing pay off) I found python quite comfortable. Somehow the problems strong static typing addresses aren't a problem. Yes and no. The problem is that static typing addresses certain problems, and provides a 90-98% solution. But that makes the remaining bugs much nastier, because nobody expects them in a static type checked program. Especially the type system of C++ is not powerful enough to express certain things. On the other hand it provides for really obscure features. How many C++ developers do know that casting can change the pointer value? (Hint: Multiple inheritence) So static typing gives in practice: a) more lines of code (because variables have to type declared) b) catches most errors of type errors. c) forces one sometimes to hack around the type system. (AFAIK void * hasn't been removed from C++, nor all that ugly casts ;) ) d) makes it harder to find type errors when you get them, because nobody expects them anymore. - data hiding Surely you can hide data in python? You can't genuinely hide data in Python. The best you can do is the _ idiom. The question is why was data hiding invented in the first place. It prevents attempts to get at the underlying mechanisms instead of sticking with the external API. There are two reasons for this: Actually, Python provides even more data hiding than say C++. In C++ if you look at the class
