DICTIONARIES IN PYTHONIN PYTHON code example

Example 1: 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"
