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"))

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

Using "key"

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

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
