Vim insert row number

Range () is a new function used to generate a list containing a number sequence. Of course, it can also be used to generate row numbers:

"Add the row number for the first 30 rows: for I in range (31): Call setline (I, I.''. Getline (I): endfor

For the usage of range () and setline (), see the help documentation.

The range () function is much more flexible than the previous two solutions. In addition to representing row numbers, it can also be used to compile numerical sequences, which also requires some programming basics.
