python創(chuàng)建空元組

Python | 空元組 (Python | empty tuple)

In python, we can also create a tuple without having any element. An empty tuple is created using a pair of round brackets, ().

在python中，我們也可以創(chuàng)建一個(gè)沒(méi)有任何元素的元組 。 使用一對(duì)圓括號(hào)()創(chuàng)建一個(gè)空元組 。

Syntax:

句法：

tuple_name = ()

Example 1:

范例1：

# Python empty tuple creation` tuple1 = () # printing tuple print("tuple1: ", tuple1) # printing length print("len(tuple1): ", len(tuple1)) # printing type print("type(tuple1): ", type(tuple1))

Output

輸出量

tuple1: () len(tuple1): 0 type(tuple1): <class 'tuple'>

Example 2:

范例2：

We can also create an empty tuple by initializing the tuple with tuple() – generally this method is used to clear/reinitialize the tuple.

我們也可以通過(guò)使用tuple()初始化元組來(lái)創(chuàng)建一個(gè)空元 組 -通常，此方法用于清除/重新初始化元組。

# Python empty tuple creation` tuple1 = tuple() # printing tuple print("tuple1: ", tuple1) # printing length print("len(tuple1): ", len(tuple1)) # printing type print("type(tuple1): ", type(tuple1)) print()# non-empty tuple tuple2 = (10, 20, 30, 40, 50) # printing original tuple print("tuple2: ", tuple2) print()# reinitialize tuple2 = tuple() print("After reinitialize...") # printing tuple print("tuple2: ", tuple2) # printing length print("len(tuple2): ", len(tuple2)) # printing type print("type(tuple2): ", type(tuple2))

Output

輸出量

tuple1: () len(tuple1): 0 type(tuple1): <class 'tuple'>tuple2: (10, 20, 30, 40, 50)After reinitialize... tuple2: () len(tuple2): 0 type(tuple2): <class 'tuple'>
