Python 内建函数 - tuple([iterable])

Manual

Rather than being a function, tuple is actually an immutable sequence type, as documented in Tuples and Sequence Types — list, tuple, range.

直译

与其说是函数，tuple实际上是一个不可变序列类型，详情参考元组和序列类型 — list、tuple、range

实例

# 元组创建方式1
>>> tuple(i for i in range(10))
(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
>>> tuple()
()

# 方式2
>>> a = (1, 2, 3, 4)
>>> a
(1, 2, 3, 4)

# 可用于赋值
>>> a, b = (3, 10)
>>> a
3
>>> b
10
