接下来,我们通过一个示例来演示如何使用这个swap函数: # 示例列表my_list=[1,2,3,4,5]# 打印交换前的列表print("交换前的列表:",my_list)# 进行元素交换swap(my_list,1,3)# 打印交换后的列表print("交换后的列表:",my_list) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 执行上述代码后,输出...
defswap_elements(lst):# 遍历列表,步长为2foriinrange(0,len(lst)-1,2):# 交换位置lst[i],lst[i+1]=lst[i+1],lst[i]returnlst# 示例列表example_list=[1,2,3,4,5,6]# 调用函数swapped_list=swap_elements(example_list)print(swapped_list)# 输出: [2, 1, 4, 3, 6, 5] 1. 2. 3....
The result is a series oftuples, where each tuple contains the corresponding elements from the rows of the original matrix. Example 3: Rearrange 2D List Using NumPy In this final example, we will use thetranspose() functionfrom Python’sNumPy libraryto transpose the 2D list. ...
Again, the number of elements in the tuple on the left of the assignment must equal the number on the right. Otherwise, you get an error. Tuple assignment allows for a curious bit of idiomatic Python. Sometimes, when programming, you have two variables whose values you need to swap. In ...
Here is Python code to access some elements of a:>>> a[0] 'foo' >>> a[2] 'baz' >>> a[5] 'corge' Virtually everything about string indexing works similarly for lists. For example, a negative list index counts from the end of the list:...
foriinlist(perm): print(i) 输出: (1,2,3) (1,3,2) (2,1,3) (2,3,1) (3,1,2) (3,2,1) 它生成 n! 如果输入序列的长度为 n,则排列。 如果想要得到长度为 L 的排列,那么以这种方式实现它。 # A Python program to print all ...
