Python学习笔记9_元组(Tuple) 1、修改元祖 2、删除元祖 3、元组运算符 4、元组截取 5、元组内置函数 6、元组不可变 Python 的元组与列表类似,不同之处在于元组的元素不能修改。 元组使用小括号( ),列表使用方括号[ ]。 元组创建很简单,只需要在括号中添加元素,并使用逗号隔开即可。 >>> tup1 = ('Google'...
Python Code: # Create a tuple containing a sequence of numberstuplex=(4,6,2,8,3,1)# Print the contents of the 'tuplex' tupleprint(tuplex)# Tuples are immutable, so you can't add new elements directly.# To add an element, create a new tuple by merging the existing tuple with the ...
Example Add elements of a tuple to a list: thislist = ["apple", "banana", "cherry"] thistuple = ("kiwi", "orange") thislist.extend(thistuple) print(thislist) Try it Yourself » Exercise? What will be the result of the following syntax:mylist = ['apple', 'banana', 'cherry'...

Can we add Py_TuplePack1 and Py_TuplePack2 to the cpython interface? If so, should it be in the public or private API. If we add Py_TuplePack2 should we use it at all places applicable, or only the few performance critical ones? An alternative for Py_TuplePack1 that already exists...
