thanks for your video!, I was able to use it to understand how to make a self building dictionary, much appreciated
dictionary = {} # dictionary is a container data type for key: value
i=0
while i < 10:
p = str(i)
key = str("Item " + p) # this is the key string
value = i + 1000 # this is the value integer
dictionary[key] = value #this is the line that populates the dictionary each time thru the loop
i = i + 1 #this iterates thru the loop until 10 is reached
print(dictionary)
print(dictionary.get("Item 4"))

I'm glad you enjoyed it ❤️

Thank you very much

Thankyou for this, how do you search for an item in a dictionary using either key or value?

[@HankTheTankCoding]

Using "key"

[@sanjroks]

Nice one! What if we want to store name and marks both for a particular roll number?

[@HankTheTankCoding]

One key can only hold one value, so im afraid we can't, we will need to add something else to differentiate between two keys

[@sanjroks]

@@HankTheTankCoding if we try to insert another dictionary inside the roll key as values?

[@HankTheTankCoding]

@@sanjroks yep you can do that, you can have nested dictionaries no prob with that 😉

[@sanjroks]

@@HankTheTankCoding Alright I am lazy to do that by myself 😄

[@HankTheTankCoding]

Haha!
