How can I record the print values?

Question

I want to record the values of this line "print(indicator)". So I would be able to get the max value and print the biggest word of the input. Look at this code below:
txt = input()
txt_list = list(txt)

indicator = 0
for c in txt_list:
indicator += 1
if c == " " or c == ",":
indicator -= 1
print(indicator)
#big_word = max(record)
indicator = 0
:D
