Delete DataFrame if condition is true

I'm sorry if this is obvious (I feels like it should be). I am downloading stock data using a for loop to create a set of dataframes labeled with the ticker name. I wish to not download stocks that return less than x rows in the downloaded data.

I currently have this that is not working?

with open('Tickers/25_tickers.csv') as f:
    lines = f.read().splitlines()

    for Symbol in lines:
        print(Symbol)
        vars()[Symbol] = pd.DataFrame()
        vars()[Symbol] = yf.download(Symbol, start, end, interval= '1d')
        i = vars()[Symbol].shape[0] #try to remove empty and low row df.
        if i > 10 == True:
                pass

When I use %whos DataFrame I get the list of 'ticker' DataFrames and the problem DataFrames still exist. I'm also not sure if I should do it while downloading or after the dataframes are in. Any help would be great. Thank you.
