List traversal in Python

In C ++, the following traversal methods are commonly used:

For (int I = 0; I

 

  
In Python, iterators are often used to traverse the list, as shown below:

  


  
For it in lst: # automatically call the iterator to automatically detect StopIterationprint (it)

  


  
In the above program, the index of the currently accessed element cannot be known, so there is the following code:

  


  
For I in range (len (lst): print (lst [I])

  


  
You can also use the built-in enumerate function by combining the index and iterator. The Code is as follows:

  


  
For index, it in enumerate (sequence): process (index, it)
