Python TypeError: unhashable type: 'slice' in dictionary

I am getting this TypeError in this simple code, appending a value to a dictionary.

dict = {}
dict['key' : 'value']
print(dict)

You can't add like this, it's a dictionary that takes key and value as a separate entity like

dict['key'] = 'value'

After doing this, the dictionary will automatically convert itself like-

dict['key' : 'value']

well you can do much more d={} for appending to it you can do

d={'key1':'value1','key2':'value'}

also 

d.update(key3:'val3')

hope this helps

dict = {}
dict['key'] = 'value'
print(dict)

[index1 :index2 ] is list slice operation, which will not work on dict
