有没有办法可以保存用户输入然后在 python 中重用它？

Question

i have this program that asks for their password and i would like to save what the user has inputted into a file then reuse it later.

while True:
user_input=""

FB=input("What is your Facebook password? \n ")
print("Your Facebook password is " + FB + " is this correct?")

user_input=input()
if user_input == "yes":
    print("password has been saved")
    break
elif user_input == "no":
    print("password was not saved \n")
else:
    print("i do not understand. Sorry")
    break

Answer 1

I wouldn't recommend storing passwords in flat file. there are many ways of storing information securely, eg in database. but if you're not concerned with security writing to a text file is very simple:

with open('secret.txt', 'a') as s:
    s.write(FB + '\n')
