dictionary in python
# Dictionaries in Python are used to store set of data like Key: Value pair # the syntax of a dictionary in Python is very simple we use {} inside that # we define {Key: Value}, to separate multiple values we use',' programming_dictionary = { "Bug": "An error in a program that prevents the program from running as expected.", "Function": "A piece of code that you can easily call over and over again.", "Loop": "The action of doing sommething again and again", } # to retrieve the values from a dictionary we use the Key name as an Index # retrieving the Function's definition print(programming_dictionary["Function"]) # this will print the definition of Function # if you wanna print all the entries in the dictionary you can do that by for loop for key in programming_dictionary: print(programming_dictionary[key]) # prints all entries # adding items to a dictionary # the following code will add another entry to the dictionary called Variable programming_dictionary["Variable"] = "The label to store some sort of data" print(programming_dictionary["Variable"]) # editing the values of a key # editing the value of variable programming_dictionary["Variable"] = "Variables are nothing but reserved memory locations to store values. This means that when you create a variableyou reserve some space in memory" # if you learnt something from this please upvote it
