pd.style.applymap only to 1 CELL , accesed by row and column name/index

Question

for index, rows in taxcode[['ITC Tax Code']].iterrows():
if str(taxcode['ITC Tax Code'][index]).endswith('ZERO') and taxcode['% VAT rate verification'][index] == 0.0:
    print(f"Culoare verde pentru: {str(taxcode['ITC Tax Code'][index])}")
elif str(taxcode['ITC Tax Code'][index]).endswith('ZERO') and taxcode['% VAT rate verification'][index] != 0.0:
    print(f"Culoare rosie pentru: {str(taxcode['ITC Tax Code'][index])}")
elif str(taxcode['ITC Tax Code'][index]).endswith('STD') and round(taxcode['% VAT rate verification'][index]) == 20:
    print(f"Culoare verde pentru: {str(taxcode['ITC Tax Code'][index])}")
    print(taxcode['% VAT rate verification'][index])
elif str(taxcode['ITC Tax Code'][index]).endswith('STD') and round(taxcode['% VAT rate verification'][index]) != 20:
    print(f"Culoare rosie pentru: {str(taxcode['ITC Tax Code'][index])}")
    print(taxcode['% VAT rate verification'][index])

so i have this code that checks for each row of a column if it has ZERO, and from the same row but from another column if the value is indeed 0. if this are met, i want to apply a background color to the %VAT rate verification column at the specific index.

i tried adding this after the check

    if str(taxcode['ITC Tax Code'][index]).endswith('ZERO') and taxcode['% VAT rate verification'][index] == 0.0:
    print(f"Culoare verde pentru: {str(taxcode['ITC Tax Code'][index])}")
    taxcode['% VAT rate verification'][index].style.applymap('background-color = green')

but i get this error : AttributeError: 'float' object has no attribute 'style'

my question is, how can i apply a background color only to that cell at [column name][index] ?
