How to print out values from two keys?

So I have trouble to print out two value that are from a list that I have created.

Basically I did a list of:

[
  {
    'Numbers': '1',
    'Name': 'Hello'
  },
  {
    'Numbers': '2',
    'Name': 'There'
  },
  {
    'Numbers': '3',
    'Name': 'Stack'
  },
  {
    'Numbers': '4',
    'Name': 'OVerflow'
  }
]

Right now if I basically call that function which is

names_number()

It would give me that values.

So of course you would use a for loop which will print each of these for its own so in that case a loop that looks like:

for i in names_number(): print(i)

That would give me:

{'Numbers': '1', 'Name': 'Hello'}
{'Numbers': '2', 'Name': 'There'}
{'Numbers': '3', 'Name': 'Stack'}

The problem now is that I want it to print out only

1 Hello
2 There
3 Stack

and I have no idea how I would in that case print out just the values of each of this everytime it for loops. I would appreciate any tip or solution on how I can continue to make a output like I wish above

The default separator for print is a single whitespace, so you use a simple for loop:

for d in L:
    print(d['Numbers'], d['Name'])

Or using f-strings (Python 3.6+):

for d in L:
    print(f"{d['Numbers']} {d['Name']}")

Here's a convoluted functional solution:

from operator import itemgetter

fields = ('Numbers', 'Name')
print(*(f'{num} {name}' for num, name in map(itemgetter(*fields), L)), sep='\n')

1 Hello
2 There
3 Stack
4 OVerflow

I would probably do something like this:

item_list = [
  {
    'Numbers': '1',
    'Name': 'Hello'
  },
  {
    'Numbers': '2',
    'Name': 'There'
  },
  {
    'Numbers': '3',
    'Name': 'Stack'
  },
  {
    'Numbers': '4',
    'Name': 'OVerflow'
  }
]

for item in item_list:
    print (" ".join([item["Numbers"], item["Name"]]))

Which produces:

1 Hello
2 There
3 Stack
4 OVerflow

Pretty much looping the list, and the printing out the key/value pairs.

I would do it like this:

for doc in lst:
    print(doc['Numbers'], doc['Name'])

Wich produces the desired out

How about that:

for dct in lst:
  print('{} {}'.format(dct['Numbers'], dct['Name']))

which produces the desired:

1 Hello
2 There
3 Stack
4 OVerflow

Note that if you did not care about the order of the items (1 Hello or Hello 1), or if you are using Python 3.6+ you can use the more elegant:

for dct in lst:
  print('{} {}'.format(*dct.values()))
