'How to use a "for loop" to search for a correct password out of a big list of potential passwords [closed]

I recently participated in a capture the flag event in a beginners cyber security class. One of the challenges was to write a "for loop" to check for the correct password out of a big list (over 1000). How would I accomplish this quickly? Or is a "for loop" even the best way to do it? (I have a txt file containing all possible passwords)

myGuessedPassword = "PythonIsGr8"

with open("my_password_file.txt", "r") as f:
    my_password_list = f.readlines()
    for passwd in my_password_list:
       if passwd == myGuessedPassword:
         print(passwd)
    else:
       print("The password was not in the file")

With python, you can simply read the the file into a list assuming they are in a text file.

Sudo code -

pwList = reader(file)

for word in pwList:

if word == “password”

print (“Found password - “,word)

Or you can check to see if word is in list.

if password in pwList:

print(“Password exists in list”)
