Multidimensional DICTIONARY?

Multidimensional DICTIONARY?

Using this we can create dictionary keys to contain list, tuple, set, and dictionary objects to represent multiple data. It is used to manage the record of multiple entities using single objects.

Syntax of Multidimensional Dictionary:-

var = {'key': list | set | dict,...}

s = {'A':[101,102,103],'B':[34,56,78]}

Now I will contain multiple employee records and display them.

Solution:-

emp = {"empid":[1001,1002,1003],"empname":["xyz","abc","mno"],"job":["mgr","cleark"]}

for key in emp:

    print(key)

    for val in emp[key]:

        print(val,end=' ')

    print()    

Dictionary can contain List, Tuple, Set, and Dictionary type Objects?

1)  Dictionary to List

emp = {"empid":[1001,1002,1003],"empname":["xyz","abc","mno"],"job":["mgr","cleark"]}

Display elements:-

for key in emp:

    print(key)

    for val in emp[key]:

        print(val,end=' ')

    print()    

2)  Dictionary to Tuple

emp = {"empid":(1001,1002,1003),"empname":("xyz","abc","mno"),"job":("mgr","cleark")}

Display elements:-

for key in emp:

    print(key)

    for val in emp[key]:

        print(val,end=' ')

    print()    

3)  Dictionary to Set

emp = {"empid":{1001,1002,1003},"empname":{"xyz","abc","mno"},"job":{"mgr","cleark"}}

Display elements:-

for key in emp:

    print(key)

    for val in emp[key]:

        print(val,end=' ')

    print()    

4)  Dictionary to Dictionary

emp = {"branch1":{"empid":1001,"empname":"Jay Kumar"},"branch2":{"empid":1002,"empname":"Manish Kumar"}}

Display elements:-

for key in emp:

    print(key)

    for val in emp[key]:

        print(val,emp[key][val],end=' ')

    print()    

Another Example of Dictionary to Dictionary and List:

student = {"A":{"rno":[1001,1003,1005],"sname":["Manish","Jay","Ravi"]},"B":{"rno":[2001,2003,2005],"sname":["Sachin","Vijay","Kavi"]}}

print(student["A"]["rno"][2])

for s in student:

    print(s,end=' ')

    for d in student[s]:

        for e in student[s][d]:

          print(e,end=' ')

    print()    

           

5)  Dictionary to all:-

we can store any type of objects under a dictionary key

emp = {"branch1":{"empid":1001,"empname":"Jay Kumar"},"branch2":[1002,"Manish Kumar"]}

for key in emp:

    print(key)

    for val in emp[key]:

        if(type(emp[key]).__name__=='dict'):

           print(val,emp[key][val],end=' ')

        else:

           print(val,end='')

    print()    

ASSIGNMENT OF DICTIONARY?

create a multi-dimension dictionary to store five student records and display max, min, total fees of students.

rno name branch fees
1001 xyz  CS       45000
1002 abc   IT       22000

The solution of This Program:-

stu = {'rno':[1001,1002],'sname':['manish','ramesh'],'branch':['CS','IT'],'fees':[45000,12000]}

for key in stu:
    print(key,end=' ')
print() 
for j in range(0,len(stu['rno'])):
    print(str(stu['rno'][j])+" "+stu['sname'][j]+" "+stu['branch'][j]+" "+str(stu['fees'][j]))
 

Assignment of Dictionary Objects:-

WAP to convert a dictionary to set and set to the dictionary.

WAP to convert a dictionary to list and list to the dictionary.

WAP to create a multi-dimensions dictionary?

WAP to create a multi-dimension set?

Solution:-

stu = set({2,3,4,5,6,7})  # set to set, set to list, set to tuple, set to dict

for k in stu:

    print(k)

    

WAP to convert Multi dimension Dictionary to Set?

The solution to this assignment:-

stu = {"a":{"a1":10,"a2":20},"b":{"b1":100,"b2":200}}

set1 = set()

set2 = set()

set3 = set()

for k in stu:

    print(k)

    set1.add(k)

    for j in stu[k]:

        print(j,stu[k][j])

        set2.add(j)

        set3.add(stu[k][j])

print(set1, set2, set3)        

        

WAP to convert set to a dictionary?  means create a dictionary under a set

WAP to convert set to a tuple?

WAP to convert tuple to set?

WAP to convert set to list?

WAP to create Mark-sheet Program using Dictionary?
