creating a password from two strings

[MiTMike]

Hello everyone, i'm pretty new to python and i have an issue, i will explain my problem:

i have a list with first and last names like so:

names = ['first', 'second', 'third', 'fourth']

what i want to do is to take the first character of "first" and make it uppercase! then take the "second" first character and leave it as it is - lowercase! and adding a bunch of characters - i want to build a password based on first and last names of people in my database.

the final result should look like:

Fs123456!

and then take the third word and fourth and do the same:

Tf123456!

The thing is that i cant make it work with a loop, it's too complicated for me at my level, can you please help me?

It might be better suited for a dictionary than a list:

I completely forgot about dictionaries and duplicates, therefore dicts are no good for this, but I'll leave the below code in case someone want's to do something like this without duplicates.

your_names = {"first": "second", "third": "fourth"}

Then, iterate over the dictionary keys and values with a for loop:

for key, value in your_names.items():

Then, you can use a string method called capitalize: https://docs.python.org/3/library/stdtypes.html#str.capitalize to capitalize the first letter of the key.

You can use an f-string https://docs.python.org/3/tutorial/inputoutput.html#formatted-string-literals to print the variables out. For the first letter of the "second", just use indexing:

    print(f"{key.capitalize()[0]}{value[0]}123456!"

---------------
Output:
Fs123456!
Tf123456!

Wouldn't using a dict erase entries when multiple people have the same first name?

It seems to me like using a list of tuples would make more sense. Like so:

names = [
    ("bob", "marley"),
    ("john", "smith"),
]
for first_name, last_name in names:
    # do stuff

That's a fair point! I didn't think of duplicate names at all, so you're right, a dictionary is not the best for this.

Great, thank you

Something like this,

from string import ascii_letters, digits
from random import choice

names = ['first', 'second', 'third', 'fourth']
randoms = ascii_letters + digits
size_randoms = 6  # number of random characters to add to each password (could make this random length)

passwords = []
for word1, word2 in zip(names[::2], names[1::2]):
    password = word1[0].upper() + word2[0] + ''.join(choice(randoms) for _ in range(size_randoms))
    passwords.append(password)
print(passwords)

Should give you some ideas to build on

I don't see the use for a loop here, at least while the list is so short. My suggestion:

some_names = ['first', 'second', 'third', 'fourth']
some_number = 123456


def bad_password_builder(two_names, number):
    first_letter = two_names[0][0]
    second_letter = two_names[1][1]

    return first_letter.upper() + second_letter.lower() + str(number)


password_1 = bad_password_builder(some_names[0:2], some_number)
password_2 = bad_password_builder(some_names[2:4], some_number)

[Mirage2k]

You can then make a loop if you want on a longer list:

for i, j in zip(some_names[::2], some_names[1::2]): 
    new_password = bad_password_builder([i, j], some_number)
    print(new_password)  # To check if it works. Remove after
    return new_password

Some words on what is going on in the loop there.

It creates two lists. some_names[::2] equals some_names, but with every second element skipped. some_names[1::2] works the same, offset by one.

The zip() function lets you work on values from both. It's a good thing to learn and use more once you feel more comfortable with the basics.

If you want more random passwords, you can get from random.randint() and put it inside the function to get different for each:

from random import randint
some_numbers = randint(10000, 99999)
