[Python] Compare string variables to another string variables

I am trying to compare digits of a string to other digits of another string. guess_str is my input turned into a string and then num_str is the randomly generated number turned into a string.

Example:

guess_str: 100

num_str: 201

How can I have it compare the two strings so that when I type 100 as guess_str it will compare to num_str showing that the number "1" that was input is part of num_str but not in the same spot?

In this I am wondering only about the second elif statement.

num = random.randint(100,999)
attempts = 1
max_attempts = 10

print(main())
print(num)

while attempts <= max_attempts:
guess = int(input(f"Guess#{attempts}:\n> "))
if guess == num:
print("Hooray!! That is the correct number!")


answer = input("Enter yes or no: ")
if answer.lower() == "yes":
main()
elif answer.lower() == "no":
print("Ok have a great day!")
break

else:
guess_str = str(guess)
num_str = str(num)

for i, val in enumerate(str(num)):
if guess_str == val:
print("Fermi".format(i))

elif any(x in num_str for x in guess_str):
print("Pico")

elif guess_str != num_str:
print("Bagels")
break

#adds attempt to game
else:
attempts += 1
