multiple_elements_tuple=(2,'b',3.14159,[4,5]) 2.2 访问元组元素 元组中的元素可以通过索引来访问,索引从0开始: my_tuple=(1,'apple',3.14)first_element=my_tuple[0]# 1second_element=my_tuple[1]# 'apple' 切片操作也可以用于获取元组的一部分: slice_of_tuple=my_tuple[1:3]# ('apple', 3.1...
# So let's create a new tuple as follows tup3 = tup1 + tup2 print (tup3) When the above code is executed, it produces the following result − (12, 34.56, 'abc', 'xyz') Delete Tuple Elements Removing individual tuple elements is not possible. There is, of course, nothing wrong ...
set -> set() # only care about presense of the elements, constant time O(1) look up dict -> {} # constant time O(1) look up for hash maps tuple -> () # tuple is a like a list but you cannot change the values in a tuple once it's defined. Tuples are good for storing ...
Printing elements between Range 4-9:('S', 'F', 'O', 'R', 'G')删除元组元组是不可变的,因此它们不允许删除其中的一部分。使用 del() 方法将删除整个元组。注意-删除后打印元组结果为错误。# Deleting a TupleTuple1 = (0, 1, 2, 3, 4)del Tuple1print(Tuple1)内置方法 学习的同时编程资料...
This is exactly analogous to accessing individual characters in a string. List indexing is zero-based as it is with strings.Consider the following list:>>> a = ['foo', 'bar', 'baz', 'qux', 'quux', 'corge'] The indices for the elements in a are shown below:...
