Python：添加元组的解压缩值（字符串）

Question

Is there a single line command to add two strings contained in a tuple to two existing strings in a program?

This is essentially what I want to do but in a shorter way,

t=("hi","hello")
x="test"
y="python"
x+=t[0]
y+=t[1]

I was thinking maybe there is a code like this that actually works,

x+,y+=t

Using python's in place addition with unpacked tuples - I really liked the complex number solution given in this similar question, but I cannot use it since my values are strings. Or is there a way I can manipulate my data (without going into too many lines of code) so that this method can be used?

Answer 1

Using this answer from the question you linked, you can do this:

from operator import add

t = ("hi", "hello")
x = "test"
y = "python"

x, y = map(add, (x, y), t)

Honestly, it is rather hard to read and I would advise against using it. As far as default Python syntax goes, I doubt there is anything you could use.

Answer 2

A single line of code doing what you expect is given below,

Code:

x, y = ["".join(i) for i in zip([x,y], t)]

Here zip() makes an iterator which aggregates the elements from each of the sequences passed to it. In this case it would be [(x, t[0]), (y, t[1])] . .join() concatenates the elements of the list passed to it with a separator ( "" in this case).
