🔒 dictionary formatting

[oblique mantle]

i have a dictionary in the format {x: [a, b, c...]} and i'd like to format it as x, a, b, c...
any ideas for how to go about this?

Can you share the dictionary?

unpacking would make this quite simple

!e

data = {'x': ['a', 'b', 'c']}


for k, v in data.items():
    print(k, *v, sep=', ')

@oblique mantle still there?

[oblique mantle]

what does sep do?

>>> help(print)
Help on built-in function print in module builtins:

print(*args, sep=' ', end='\n', file=None, flush=False)
    Prints the values to a stream, or to sys.stdout by default.

    sep
      string inserted between values, default a space.
    end
      string appended after the last value, default a newline.
    file
      a file-like object (stream); defaults to the current sys.stdout.
    flush
      whether to forcibly flush the stream.

thank you! it works well

[oblique mantle]

another question, what does *v do?

[novel tartan]

* before an iterable will unpack its contents into arguments

since print accepts unlimited arguments, it will place each item as a separate argument

data = ['a', 'b', 'c']

print(*data)
# Is basically the same as
print(data[0], data[1], data[2])

these are basically the same

[oblique mantle]

okay cool that makes sense

[novel tartan]

but with *data, it doesn't matter how many items there are inside the list

[oblique mantle]

so would it be the same as going

data[0:]?

[novel tartan]

no, because that's still a list

[novel tartan]

Look at my example here

[oblique mantle]

isn't that a list as well?

[novel tartan]

data[0] is not a list

it's a string

"unpacking" is taking the elements of the list one at a time and passing them as arguments

!e

data = ['a', 'b', 'c']

print(data)
print(*data)

001 | ['a', 'b', 'c']
002 | a b c

[novel tartan]

look at the difference

[oblique mantle]

that makes sense. thank you for the help!

[novel tartan]

Np! If that's all for now, you can close this thread with !close
