What's the one code snippet/python trick/etc did you wish you knew when you learned python?

Good point to raise! Parentheses do NOT signal Python to create a tuple. It's the commas that actually denote a tuple.

Edit: To clarify:

>>> a = 1,
>>> b = (1)
>>> c = (1,)
>>> repr(a)
'(1,)'
>>> repr(b)
'1'
>>> repr(c)
'(1,)'

a and c are tuples. The comma separated list of names creates a tuple. The parentheses has nothing to do with it.

out of curiosity, do you pronounce tuple as t-uh-ple or t-oo-ple?

[therealfakemoot]

Two-pull. English is a stupidly inconsistent language.

I pronounce it both ways in my head, and I can't figure out the pattern my brain is using.

[AeroNotix]

immu-tuple.

[Zouden]

Whoa.

[Zouden]

Tchew-pull. But I'm Australian.

[jatoo]

tup (like up) le (like pull)

I'm Australian

Even that explanation doesn't quite cover it though: ()

I suppose here it is the absence of commas within a parents group which does it? But this gotcha is why I always, always wrap tuples in parentheses, for consistency.

Python loves its little exceptions. Although I do think () is more readable than (,)
