Python Code:# Create a tuple containing a sequence of items tuplex = ("w", 3, "r", "e", "s", "o", "u", "r", "c", "e") # Print the contents of the 'tuplex' tuple print(tuplex) # Get the 4th element of the tuple (index 3) item = tuplex[3] # Print the value of...
Getting the last n elements of a list in Python. You can use the slicing operator[-N:], where N is the number of elements you want to retrieve from the end of the list. You can get the last n elements of a list in Python using many ways like, list slicing, loop, islice() + ...
The main difference is that lists in Python cancontain elements of different types. They're heterogenous. # List of different type elementsexample_list = ["string",5,"five",4,"4"] Note:If elements are not comparable via thecomparison operators (<,>,==,!=), themax()function won't wor...
从元组中获取值的方法十分简单,主要通过索引来实现。Python 中的索引从零开始计数。这意味着,第一个元素的索引是0,第二个元素的索引是1,依此类推。 使用索引获取元素 我们可以通过下列方式访问元组中的元素: # 获取元组中的元素first_element=my_tuple[0]# 访问第一个元素second_element=my_tuple[1]# 访问第...

In Python, lists and tuples are collection objects that can contain multiple values. Sometimes, you need to get the number of elements contained in these objects. When using the NumPy library, you can find the shape of an array using the.shapeproperty: ...
elements from a list. In python, we can use positive indices as well as negative indices. Positive indices start with zero which corresponds to the first element of the list and the last element of the list is identified by the index “listLen-1” where “listLen” is the length of ...
