spaces or tabs
Doesn't PEP 8 say spaces somewheres?
4 spaces, although I'll die on the hill that tabs should always be used instead of space for indentation. Not just in python.
- Use tabs.
- Enable visible whitespace.
Tada, your indentation level is nicely visible.
Tabs. But really with modern IDE it's irrelevant. Whatever the tech lead says I guess.
Yeah but outside of that where the code is implemented or in a documentation, tabs are still easier to look through. And it does look pretty as long as there aren't too many nested functions.
Even with nested functions tabs are neat.
Does you app have too many nested functions?
Use tab width = 2
Do your app have too less nested functions?
Use tab width = 8
Is your app having average number of nested fns?
Use tab width = 4(mostly default)
And all theese can happen without modifying a single byte in the source file, unlike spaces!
Questions like that are likely to start a war
semicolons
Full colons
4 Spaces, then one tab, then 3 spaces, then 2 tabs, then 2 spaces, then 3 tabs...
Python supports that (and I hate this)
"indentation is indentation!" (mr_incredible_cereal.jpg)
it may look messy, but would you actually rather Python didn't support some inconsistency when the intent is clear?
being exact just for the sake of being pedantic isn't useful.
Please elaborate (eg which standard is this defined in?)
Not any standard (and actually not at all something to do for real), but try it, it works
def magic(a, b, c): if a > 0: if b > 0: if c > 0: return 'All positive' return 'Not all positive' print(magic(1,2,3)) print(magic(-1,1,2)) print(magic(1,-1,0)) print(magic(-1,-1,-2))(you should be able to verify I used both tab and spaces f*cking bad way in this example, like I described)
Output:
All positive Not all positive Not all positive Not all positive ** Process exited - Return Code: 0 ** Press Enter to exit terminalThat's really interesting. So does that mean the interpreter just checks whether the current line is more indented, less indented, or equal vs. the preceding, without caring by how much?
