Replace certain part of specific line in file

Question

Edit to make it better understandable:

My file is looking something like this:

For M5|Adr    11|KD1               12:29:09    1|     
For M5|Adr    12|KD1  8964523      12:34:173   1|Lr   
For M5|Adr    13|KD1     1000      12:34:563   1|Lv   
For M5|Adr    14|KD1  bvff123      12:34:56    1|     
For M5|Adr    15|KD1               12:39:063   1|Lr   

I found out which lines need to be edited and put them into a list.

templist = list(range(anfzahl+3, endzahl-4))

Templist defines the part of the file which needs to be edited for example: Starting with line 5 until line 15.

The part which needs to be replaced with spaces is for example in this case: 8964523, 1000 and bvff123. There can stand any letter and any number or it can already be blank, it is limited to column 23 to 30 tho.

Now I am looking for a function which can (in this example) edit everything in column 23 to 30 from line 5 to line 15 and replace it with spaces.

Thanks in advance for the read and help.
