Aim:

Write a program to demonstrate working with dictionaries in python.

Source Code:

week7.py

'''Write a program to demonstrate working with dictionaries in python.'''

dict1 = {'StdNo':'532','StuName': 'Naveen', 'StuAge': 21, 'StuCity': 'Hyderabad'}

print("\n Dictionary is :",dict1)

#Accessing specific values 

print("\n Student Name is :",dict1['StuName'])

print("\n Student City is :",dict1['StuCity'])

#Display all Keys

print("\n All Keys in Dictionary ")

for x in dict1:

    print(x)

#Display all values

print("\n All Values in Dictionary ")

for x in dict1:

    print(dict1[x])

#Adding items

dict1["Phno"]=85457854

#Updated dictoinary

print("\n Uadated Dictionary is :",dict1)

#Change values

dict1["StuName"]="Madhu"

#Updated dictoinary

print("\n Uadated Dictionary is :",dict1)

#Removing Items

dict1.pop("StuAge");

#Updated dictoinary

print("\n Uadated Dictionary is :",dict1)

#Length of Dictionary

print("Length of Dictionary is :",len(dict1))

#Copy a Dictionary

dict2=dict1.copy()

#New dictoinary

print("\n New Dictionary is :",dict2)

#empties the dictionary

dict1.clear()

print("\n Uadated Dictionary is :",dict1)
