Python assigns values to multiple variables at the same time

Assigning multiple values at the same time

Here's a cool programming shortcut: In Python, you can use tuples to

Assigns multiple values.

>>> v = (' A ', 2, True)

>>> (x, y, z) = V①

>>> x

A

>>> y

2

>>> Z

True

1. V is a ternary tuple, and (x, Y, z) is a meta with three variables

Group. Assigning one of the values to another will assign each value in V in order

to each variable. This feature has many uses. Suppose you need to specify a name for a specific range of

Value. You can use the built-in range () function for multi-variable assignment to quickly

The row continuous variable assignment value.

>>> (MONDAY, Tuesday, Wednesday, Thursday, FRIDAY,

SATURDAY, SUNDAY) = range (7) ①

>>> MONDAY

Ii

0

>>> Tuesday

1

>>> SUNDAY

6

1. The built-in range () function constructs an integer sequence. (From Technology

says that the range () function returns neither a list nor a tuple, but an iterative

But you will learn the difference later. ) MONDAY, Tuesday,

Wednesday, Thursday, FRIDAY, SATURDAY and SUNDAY are what you decide

The variable that is justified. (This example comes from the Calendar module, which is a short and interesting module

Print a calendar, a bit like a UNIX program Cal. The Calendar module is the number of weeks

An integer constant is defined.

2. Now, each variable has its value: MONDAY is 0, Tuesday is 1,

So the analogy.

You can also use a multivariate assignment to create a function that returns multiple values by simply returning a package

A tuple with all values. The caller can treat the return value as a simple tuple, or

Assign it to a different variable.
