Write a Python program to append a list to the second list. Example - 1 : Example - 2 : Example - 3 : Sample Solution: Python Code: # Define a list 'list1' containing numeric elementslist1=[1,2,3,0]# Define another list 'list2' containing string elementslist2=['Red','Green','...
append是整建制地追加,extend是个体化扩编。 extend将它的参数视为 list,extend的行为是把这两个list接到一起,append是将它的参数视为element,作为一个整体添加上去的。 List里可以有任意的数据类型,所以,要分清这俩函数的区别。
python # Create an empty list my_list = [] # Append an item to the list my_list.append(1) # Print the list to see the changes print(my_list) # Output: [1] # Append another item to the list my_list.append(2) # Print the list again print(my_list) # Output: [1, 2] In...

该方法通过从可迭代对象追加元素来扩展列表:list.extend my_list.extend(iterable) 因此,通过扩展,可迭代对象的每个元素都会附加到列表中。例如: >>> my_list ['foo', 'bar'] >>> another_list = [1, 2, 3] >>> my_list.extend(another_list) >>> my_list ['foo', 'bar', 1, 2, 3] ...
5.What happens if you use append() to add a list to another list? The entire list is added as a single element to the end of the target list. 6.Is append() an efficient way to add elements to a list? Yes, append() is efficient as it adds an item to the end of the list in...
