How i can make dictionary

Question

withe .key () and value

Answer 1

keys() is usually used to return a list of all the dictionary keys in arbitrary order.
Instead, you can use :
1. dict() e.g
d=dict(lang='python', extension='.py')
#printing d out gives, {'lang': 'python', 'extension': '.py'}

2. dictionary comprehension.
e.g
squares ={x:x**2 for x in range(3,7)}
print(squares)
# gives out the key 'x', with the corresponding square of 'x', as value , within the given range :
in this case :
{3: 9, 4: 16, 5: 25, 6: 36}

3.Now, to retrieve the keys in the above dictionary using keys()
do this :
squares.keys()
#gives out :

dict_keys ([3, 4, 5, 6])

#I Hope this is useful to you.

Answer 2

Litteral assignements:

myDict1 = {} # empty dict
myDict2 = {'keyname1':42, 'keyname2':'value' }

Adding key/value pairs at run time in same way that you update a key

myDict1['key'] = 'the value to assign -- not necessarly a string, onviously'

You can get a specific key value with:

value = myDict2['keyname1'] # 42

.. or with the safer get() method wich avoid key error for undefined keys:

value = myDict1.get('undefinedkey',42)

(second parameter is the default value to return if key doesn't exist ;))

@S Vengat:

@washika deserve the best answer, I have no problem with that... because he fully explain use of dictionnaries, while I only answer to the specific unclear question about 'how make a dictionary' ('with .key () and value' wasnt enough explicit for me :P)
