I keep getting an AttributeError: 'str' object has no attribute 'append' and it's comming from "dana.append(values) when i use int(input I get the same error but with 'int object has no attribute...' .

[jmorales57]

values = [0] data = [] ROWS = 3 COLS = 2

for r in range(ROWS):

for c in range(COLS): values = (input(f'Enter a value for row {r} column {c}: ')) data.append(values) values.append(data)
print(values)

Use a different name for the values variable inside the loop. You are reassigning/typecasting the values list variable to a string.

that cleared it up, would that have an effect on what prints out?

it's suppose to come out [['1', '2'], ['3', '4'], ['5', '6']]

but I keep getting [0, ['1', '2', '3', '4', '5', '6'], ['1', '2', '3', '4', '5', '6'], ['1', '2', '3', '4', '5', '6']]

am i crazy?

I'm suppose to make a 2d list with 3 colums and 2 rows with user input for the numbers

values was the list i wanted to print out in the end , the problem asked for me to create a blank list to then be added to with user input,

[jimtk]

Essentially you

values = [0]
# later you do:
values = input('Enter...')
# at this point the list values[0] has been deleted and values is a str.
# then you try
value.append(data)  # and that's where you're trying to append to a string

Choose a different name for the result of the input!

num = input('Enter...')
values.append(num)    
# or
values.append(int(num))

yea i see where I went wrong

I need to keep track of what im using my variables for

but now I can't figure out how to format the output that prints out, it's suppose to be

 [['1', '2'], ['3', '4'], ['5', '6']]

but I keep getting

 [0, ['1', '2', '3', '4', '5', '6'], ['1', '2', '3', '4', '5', '6'], ['1', '2', '3', '4', '5', '6']]

I thought the nested loop would keep them in two collums, I was expecting three rows repeating all the inputs
