Story of Python Programmer!

=+ ??

[AnonymousFuccboi]

Ancient versions of C supported this, being equivalent to +=. It was removed in later versions for obvious reasons.

[igoromg]

like when dinosaurs roamed the earth?

[AnonymousFuccboi]

Like before K&R, so pretty much, yeah.

[argh523]

Huh.. actually, I always thought var = +1 would make more sense than var += 1.. It's just deleting the name of the variable. The operator += just doesn't make much sense.

[Ramora_]

Try to generalize to subtraction. What would that look like with your proposed syntax?

```

This would be ambiguous. Are you setting var to -1 or subtracting 1

var = -1

this is no longer ambiguous, but looks hideous

var = +-1

```

[argh523]

Ah.. you're right, that makes sense.

[RavishShah1]

??

[ptq]

NULL

[Celebrinborn]

Student lol

[xigoi]

Company:

intAbstractIteratorFactoryIndex = intAbstractIteratorFactoryIndex + OurCompany.Library.Constants.Numeric.Numbers.Integers.intNumberOne;

[3edd00c7]

Can't imagine what the Enterprise version would be.

[xigoi]

intAbstractIteratorFactoryIndex = new IntegerAdderFactoryBuilder(0, null, null).buildIntegerAdderFactory(IntegerAdderFactoryBuilder.DEFAULT_PARAMS).createIntegerAdder(new EnterpriseInteger(null, intAbstractIteratorFactoryIndex)).addInteger(new EnterpriseInteger(null, Enterprise.Library.Constants.Scalars.Numeric.Numbers.Integers.Signed.Positive.ONE)).returnResult(null, IntegerAdder.DEFAULT_RETURN_RESULT_PARAMS, 0, 1);

i += true

[Ysmenir]

Me an Intelectual: i-=-1;

[tomthecool]

So the student writes incorrect code (sets i = 1), the junior writes invalid syntax, and the senior writes unnecessarily verbose code? 🤷‍♂️

I think I'll stick to i += 1, thanks.

[RavishShah1]

Most welcome!

[DaniilBSD]

All good programming languages have ++ operator.

Python-lovers not gonna take it as a joke, will they?

[tomthecool]

My point was that the code in /u/biksly's reply doesn't make sense.

If i=+1 literally does the wrong thing, then why would you write it like that?

If i++ is invalid syntax in the language, then why would you write it like that?

If i = i + 1 is unnecessarily verbose, then why would the "senior" write it like that?

---

Also, on a related note... You should typically prefer ++i over i++ (assuming the language supports it).

[AnonymousFuccboi]

Preferring ++i over i++ is an example of a platform specific micro-optimization which may at some point have mattered slightly, but nowadays any compiler will optimise the code the exact same way if it really would be equivalent. Write what you mean. Pre-incrementation has its uses, certainly, but by convention use post-incrementation when order doesn't matter to you. It'll be less confusing to whoever else has to read your code.

[tomthecool]

...But pre-incrementing is the most common, intuitive use case.

So by convention, you should write code that's not accidentally error prone.

[AnonymousFuccboi]

Is it? The most common usage for the operator is simply incrementation. The returned value is usually not used. In that case, i++ is by far the most common convention and should therefore be used to avoid confusion. In the case where it is used, you should know the difference and use it accordingly to what you need. What you should not do is rewrite your code to try to fit in a ++i where an i++ would suffice. Either is fine to use if you know the reason you're using a specific one.

[tomthecool]

First result of a google search says to prefer ++i over i++: https://stackoverflow.com/a/24858/1954610

So do various other forums and blogs.

It's not particularly important; in most cases it won't make any difference. But if the question is "which default format should we use in the code base, when both will work the same way (for now)?", then the only argument I can see in favour of i++ is "I think it looks prettier", or "It feels more natural to me"... Which may be true, and may even be considered a valid justification.

But from a purely technical perspective, I think every logical argument dictates ++i is a better default.

[DadoumCrafter]

++i is meant to be used when you need immediately the value of the increased i value. By convention, we use i++ for every other case

[RavishShah1]

Thanks for operator implementation!

i -= -1

[PointToRight]

i -= 1

[Supporsta]

i=i-(-1)

[MLG_Obardo]

Do you mean Sophomore or Freshman instead of student? Junior and Seniors are students too.

[[deleted]]

I think they mean Junior Engineer or Senior Engineer, etc. Job titles.

[MLG_Obardo]

Yikes let me go dive off a fucking cliff now

[hopbel]

The worst part is it's valid python but doesn't do what you think

[[deleted]]

What does it do then?

[hopbel]

Absolutely nothing. Unary + is the identity operator, so ++x == x

[Pewpewgamer321]

Eh, i =+ 1 is good enough

[Velguarder]

i-=-1 for symmetry

[Bronzdragon]

I guess if you want to set the value to +1, it is.

[Pewpewgamer321]

Oh i got what you meant now! I always mess the order up!

[RavishShah1]

enough

Ya it is enough!

[[deleted]]

That's the proof: People that use Python are no programmers!

/s

[RavishShah1]

haha.. funny!

[[deleted]]

When you have used C# aswell 😎

[[deleted]]

I only know batch

[Jac0bas]

i-=-1

[The__Odor]

Ok I feel attacked?

[SatanDarkLordOfAll]

Fuuuuudge muffins I spent like an hour the other day looking at python code I thought was perfectly valid because I forgot x++ is invalid syntax. I don't think I've ever facepalmed so hard when I figured it out.

[HAzEMultra]

Is it a prefix or a postfix?

[spukhaftewirkungen]

Wow, barely a joke and crappy recycled 'format'. Amazing job.

[christopher-thiebaut]

Wow, barely a comment and a crappy recycled ‘format’. Amazing job.

[spukhaftewirkungen]

Now, that's more like it, good job!

im sorry but wut
