Some comments!!

Firstly, the upper & lowercase password can be simplified. I'd realised this after filming so it's worth mentioning! You can simplify it as follows:
password = ""
for i in range(5):
i = chr(random.randint(65, 90))
j = chr(random.randint(65, 90)).lower()
password = str(password) + i + j
print(password)

Secondly, if you want to add numbers to your password, you can!! In python we can't concatenate strings and integers (numbers). The way you overcome that is by creating a new variable which produces random integers from 0 to 9, we'll call it k, and simply putting 'str' around it. Your new code should look like this altogether,

password = ""
for i in range(5):
i = chr(random.randint(65, 90))
j = chr(random.randint(65, 90)).lower()
k = random.randint(0, 10)
password = str(password) + i + j + str(k)
print(password)

I tried this out on my own laptop and it produced 'Ht7Im9Ml2Vl1Yz0'. Awesome!

This is great! Really loving this introduction. I found that another way to shift between lower and uppercase letters, you can use modulus 2 of i.

for i in range(10):
if i % 2 ==2:
i = chr(randint(65, 90))
else:
i = chr(randint(65, 90)).lower()
password=str(i)+password

Thank you very much Ellie. As for the second part (Upper and lower case), I don't see the loop is necessary as this can be done like that:

password = ""
for i in range(5):
i = chr(random.randint(65, 90))
j = chr(random.randint(65, 90)).lower()
password = str(password) + i + j
print(password)


The second loop you used may be useful if the password needed is 50 letters in length if we just changed the indentation of the concatenation line to be beneath the second loop like that:

password = ""
for i in range(5):
i = chr(random.randint(65, 90))
for j in range(5):
j = chr(random.randint(65, 90)).lower()
password = str(password) + i + j
print(password)

Late comment in this one, I was wondering about the list relating to the number reference such as alphabet (65, 90) and vice versa for number this is using ASCII list?

[irvinrp-ven]

That's good 👍, hey, how Can I do a Pytest program to test it? Thanks

[jetspray]

J variable was initialize in the inner for loop, why was it able to be used in the outer for loop?

[tailgater]

Hello.

I want to if i can do this.

Can l make the password that get genatoar go in to a text document.

[Dotto]

Thank you for this great video. My question is how do I creat a random password with letters and numbers?

[stacyericson]

Thank you so much for this video! It's so easy to understand!! How would I add special characters?

[enchantedchoco]

hey Ellie!!! thank you for this tutorial, just to know if we can add integers into the passwords would you give an idea about how I could do that ... I'll surely google it out but wanted to know how would you do that!

PS -> I am surely an amatuer 😅🤞🏻

[jetspray]

Why did you str cast password when password is already set as a string?

[ryanruppert]

Does anyone know how I would shuffle the password so its in random order?

[anupamkasturia]

I think at 3:30, password is already a string, so I guess there is no need to convert it to a string, Correct me please If I am wrong. Nice Video, by the way.
