The insert method
The insert method adds an element to the list before the specified index. In the first parameter, we specify the index before which the element should be placed, in the second parameter - the element we want to add to the list.
Syntax
list.insert(index of what to add)
Example
Let's add the element '12' at position 2 in our list:
lst = ['ab', 'cd', 'ef', 'gh']
lst.insert(2, '12')
print(lst)
print(lst.index('12'))
Result of code execution:
['ab', 'cd', '12', 'ef', 'gh']
2
Example
Now let's add an element to the end of the list:
lst = ['ab', 'cd', 'ef', 'gh']
lst.insert(-1, '12')
print(lst)
print(lst.index('12'))
As can be seen from the result obtained, the element was added not to the end of the list, but before the last element:
['ab', 'cd', 'ef', '12', 'gh']
