list inside dictionary in python by R4R Team

- list contain only elements or items like number,string or other data typr as well.
- list work on the basis of the index value
- dictionary contain keys and value, where keys plays a role of index value.
- here key is unique value like numbers, string, not the list and value supports all type of data type.

So it is possible to insert a list at the place of values in dictionary......


program-

l=[1,2,3]
print("List is",l)
d={1:l,2:l,3:l,"one":l,"two":l}
print("Dictionary is n",d)

print(d[1])
print(d[2])
print(d[3])
print(d["one"])
print(d["two"])

output-

List is [1, 2, 3]
Dictionary is
{1: [1, 2, 3], 2: [1, 2, 3], 3: [1, 2, 3], 'one': [1, 2, 3], 'two': [1, 2, 3]}
[1, 2, 3]
[1, 2, 3]
[1, 2, 3]
[1, 2, 3]
[1, 2, 3]

-In this program, we have a list [1,2,3,4], so we pass in dictionary as a value for each and every keys of dictionary.

-If we try to put list at the place of keys like


program-

l=[1,2,3]
d={l:l}
print(d)

output-

d={l:l}
TypeError: unhashable type: 'list'

-That means we can't put the list at the place of keys in dictionary in python.
