Python list counts and inserts instances

This example demonstrates the use of Python list counting and inserts. Share with you for your reference. The details are as follows:

word=['a','b','c','d','e','f','g']//The first element is element 0, word[0]= a&cake; & have spent < br / >
a=[num1:num2]                                     

//Elements from num1 to num2 (not including the element num2) & NBSP; & have spent & have spent & have spent < br / >
// If it's negative, it's the reciprocal 

 
When operating on the list, append appends word. Append (elements)
Elements is independent. If it is list, append it as a whole after word instead of extending word.
Word. Extend (elements) is to extend, extend the element contained by elements into insert() after word, insert:

word.insert(mum,elements)

What is inserted is also a whole.
