how to avoid headers repeating everytime I append in Pandas

Im trying to append values from stored values taken from users. Is there a way to hard code the headers ("Player Name", "Age" and "Number") so evertime I run the code these headers dont appear again in the csv.

Edit: I want the headers to appear the "First time" it runs and not the ones after

data = {'Player Name': [playersNames[0]],
        'Age': [Age[0]],
        'Number': [number],

        df = pd.DataFrame(data)
        df.to_csv("Info.csv",mode='a',index=False, header=True)
        print(df)

At the moment it does this:

Player Name,Age,Number
x,15,73
Player Name,Age,Number
y,25,70

>Solution :

Try:

import pathlib

csvfile = pathlib.Path('Info.csv')
df.to_csv(csvfile, mode='a', index=False, header=not csvfile.exists())
