I have searched several ways on applying a bold to a text however unable to achieve it.

Have added '\033[1m' then my text and followed by '\033[0m', however cant see the text as bold.

I need to apply Bold to the Header "Ocean" in below image which is in Dataframe

for row in Nlargest_map_df.index:

 array = '\033[1m'+""+Nlargest_map_df['County'][row]+'\033[0m'+"\nMarket Size : "+Nlargest_map_df['Market Size'][row]+"K"+"\nMarket Growth : "+Nlargest_map_df['Market Growth'][row]+"%"+"\nMarket Leader : "+Nlargest_map_df['Market Leader'][row]+"\n"
