Issue 1656538: dict(key,values) initializer - Python tracker (original) (raw)

Far too often I use the idiom dict(zip(keys,values)), or the same with izip. How does letting dict take two positional arguments sound ?

Pros:

• Pretty obvious semantics, no mental overhead to learn and remember it.
• More concise (especially if one imports itertools just to use izip).
• At least as efficient (and probably more) as the current alternatives.
• Backwards compatible.
