how to make each key-value of a dictionary print on a new line?

Iterate over dict.items and print:

>>> d = {'avglen': 4.419354838709677, 'count:': 93, 'mosts:': 'your', 'longs:': ['stretched'], 'shorts:': ['i', 'a'],}
>>> for k, v in d.items():
...     print (k, '-->', v)
...     
mosts: --> your
count: --> 93
avglen --> 4.41935483871
shorts: --> ['i', 'a']
longs: --> ['stretched']

Or use the pprint module:

>>> import pprint
>>> pprint.pprint(d)
{'avglen': 4.419354838709677,
 'count:': 93,
 'longs:': ['stretched'],
 'mosts:': 'your',
 'shorts:': ['i', 'a']}

You may be looking for pprint, the pretty printer standard library. For example:

import pprint
pprint.pprint({'avglen': 4.419354838709677, 
               'count:': 93,
               'mosts:': 'your',
               'longs:': ['stretched'],
               'shorts:': ['i', 'a'],})

outputs

{'avglen': 4.419354838709677,
 'count:': 93,
 'longs:': ['stretched'],
 'mosts:': 'your',
 'shorts:': ['i', 'a']}

In your past six questions or so, you seem to be using this poor dictionary as a text-indexed object of sorts. Why not make it a proper class?

for those of you using pprint wondering why your dictionary still wont print each entry to a new line: could be that your dictionary entries or the whole dictionary are too short. in this case, invoke the PrettyPrinter class directly and set the width argument accordingly, as specified in the docs:

import pprint
stuff = {'avglen': 4.41, 'count:': 93, 'shorts:': ['i', 'a']}
pretty = pprint.PrettyPrinter(width=30)
pretty.pprint(stuff)

For a quick print you could use string replace to put newlines into the output. This method does not give beautiful results if the dictionary contains lists; those lists will also get newlines.

td = {'avglen': 4.419354838709677, 'count:': 93, 'mosts:': 'your', 'longs:': ['stretched'], 'shorts:': ['i', 'a'],}
print(str(td).replace(', ',',n '))

Outputs

{'avglen': 4.419354838709677,
 'count:': 93,
 'mosts:': 'your',
 'longs:': ['stretched'],
 'shorts:': ['i',
 'a']}

resources = {
    "water": 300,
    "milk": 200,
    "coffee": 100, }


for key in resources:
    print (f"{key}: {resources[key]}")

outputs

water: 300
milk: 200
coffee: 100

I found a new way to do it with json, very easy to use.

import json
dict1 = {'0': 0, '1': 70, '2': 37, '3': 11, '4': 6, '5': 5, '6': 3, '7': 1, '8': 0, '9': 0, '10': 0, '11': 0, '12': 0, '13': 0, '14': 0, '15': 0}
print(json.dumps(dict1, indent = 4))

The result should be like this:

{
    "0": 0,
    "1": 70,
    "2": 37,
    "3": 11,
    "4": 6,
    "5": 5,
    "6": 3,
    "7": 1,
    "8": 0,
    "9": 0,
    "10": 0,
    "11": 0,
    "12": 0,
    "13": 0,
    "14": 0,
    "15": 0
}

From the first answer in this thread:
How to print a dictionary line by line in Python?

Can do it this way without having to import any modules. Just iterate over the dictionary and print a new line after each key:value pair.

dict = {'1':1,'2':2,'3':3}
for key,value in dict.items():
    print(key,value,'n')
