Dictionary is very powerful in-built data type in Python which are essentially key value pairs.  

Syntax of a dictionary - {'key':'value' } 

Sample dictionary - student = {"name":"Gaurang"}

Iterating over in the dictionary -

for k,v in student.items():
    print("Name is",k,"and", "Value is",v)
print(student)

To access value of a dictionary - 

print(student['name']) 

Gaurang - #this returns the value of the key from the dictionary variable name called Student. 

#To delete the items of a dictionary, use clear()

student.clear()
for k,v in student.items():
    print("Name is",k,"and", "Value is",v)
print(student)

• dict.get(key, default) – Safe value access.

• dict.keys() – All keys.

• dict.values() – All values.

• dict.items() – All key-value pairs.

• dict.update(other_dict) – Merge dictionaries.

• dict.pop(key) – Remove a key and return its value.
