insert the same value twice in a column called 'mer_value' of a shapefile - insert

Question

Hi there, i want to insert a value between 0 and the output of function total polygons twice to the column of 'mer_value'(from the bottom left) of a shapefile so that the print output would look some thing like this.
mer_value
0.0
0.0
1.0
1.0
2.0
2.0
....
right now it only inserts the value from 0.0 all the way to the end repeating only once, like the below example.
mer_value
0.0
1.0
2.0
.....
any help is appreciated
{
import geopandas as gpd
number_of_geocells = 2
#create a funtion to read the total polygons in a given shapefile and divide it by the number of geocells and store the value in a new varialbe called "total_polygons"
def total_polygons(shapefile):
total_polygons = gpd.read_file(shapefile).shape[0] / number_of_geocells
total_geocells_per_zone_rounded = round(total_polygons)
return total_geocells_per_zone_rounded
#create a function to duplicate the shapefile and save it as a new shapefile called "zones"
def duplicate_shapefile(shapefile):
zones = gpd.read_file(shapefile)
zones.to_file("C:/tmp/shapefiletotestautomation/zones.shp")
return zones
#create a function to create a colum called 'mer_value' in the shapefile called "zones"
def create_merge_value(shapefile):
zones = gpd.read_file(shapefile)
zones['mer_value'] = zones.index
zones.to_file("C:/tmp/shapefiletotestautomation/zones.shp")
return zones
#create a loop to insert the same number twice to column "mer_value" in the shapefile called "zones"
def insert_merge_value(shapefile):
zones = gpd.read_file(shapefile)
for i in range(total_polygons(shapefile)):
zones.loc[i, 'mer_value'] = i
zones.loc[i + number_of_geocells, 'mer_value'] = i
zones.to_file("C:/tmp/shapefiletotestautomation/zones.shp")
return zones
print(insert_merge_value("C:/tmp/shapefiletotestautomation/m/GEOCELLS.shp"))
}
