Why cant I convert to float

I am trying to convert my CSV file into floats on certain ones that are numbers, However I keep getting ValueErrors.

def create_info(self, country_data):
    with open(country_data, "r") as csvfile:
      csvreader = csv.reader(csvfile)
      for words in csvreader:
    
        

        c = Country()

        c.country_name = words[2]
        c.country_code = words[3]
        c.acc_to_clean_fuel = float(words[4])
        c.acc_to_elec = float(words[5])
        c.annual_freshwater_withdrawl = float(words[6])
        c.armed_forces_tot = int(words[7])
        c.expense_gdp = float(words[8])

        self.__list_countries.append(c)
      

my CSV data is

Time,Time Code,Country Name,Country Code,Access to clean fuels and technologies for cooking (% of population) [EG.CFT.ACCS.ZS],Access to electricity (% of population) [EG.ELC.ACCS.ZS],"Annual freshwater withdrawals, total (% of internal resources) [ER.H2O.FWTL.ZS]","Armed forces personnel, total [MS.MIL.TOTL.P1]",Expense (% of GDP) [GC.XPN.TOTL.GD.ZS]

value Error

File "main.py", line 7, in main
    Info.create_info("country_data.csv")

ValueError: could not convert string to float: 'Access to clean fuels and technologies for cooking (% of population) [EG.CFT.ACCS.ZS]'

I tried to use split and strip but they were invalid in the strings

>Solution :

It seems like the first row of your CSV data are your headers — and your loop is not taking that into consideration. So you’re actually trying to convert your titles to floats.

If it’s your only case for a CSV file and it’s enough to skip the first line just in this instance, you can just add:

  csvreader = csv.reader(csvfile)
  csvreader.__next__() # This will skip the titles

Before starting your loop and your conversions should work.
