python - Is there a way to insert a single character string into selected string items in a list?

Question

for example:

list = ['a','b','c','d']

i want to insert the letter 'j' in front of the first two strings

which will make the list like this

list = ['ja','jb','c','d']

I know how to append strings into the list but not strings into the items in a list.

Answer 1

You can use list comprehension on a slice and get it done.

list1[0:1] = ['j'+x for x in list1[0:2]]

The output of this will be:

['ja', 'jb', 'c', 'd']
