Function takes in a Ticker Symbol of a company and loads a dataframe. Sometimes the Ticker is delisted or does not work. How do I eliminate?

Question

I made a function that takes in a ticker symbol and loads a data frame with the corresponding chart values for that company, I want to read the output that it gives and remove those tickers from the list that I have no data for. How should I do this?

Python Code:

#Get data Command
def get_data(tick,per,inter):
    data = yf.download(tickers=tick, period=per, interval=inter)
#Loading Ticker Symbols
df_tick = pd.read_excel(r'C:\Users\paliw\2000_tick.xlsx')
print (df_tick)
#Creating a list of Ticks
ticklist = []
for i in df_tick[['Symbol']]:
    ticklist = df_tick[i]

for i in ticklist:
    get_data(i,'1y','1d')

When I run my command then sometimes I get a failed download, I want to remove these ticker value from the list.

This is the output I am getting, I want to take all the values that say Failed Download and remove their ticker symbols from the list
