Python Loops

Python arrays are a special variable that have the ability to hold more than one value. For instance, if were a list of of car models, those models could be stored into single variables. The array can hold a fix number of elements and these elements must be the same…

Python for loops iterate over sequences such as a dictionary, list, set, or tuple. The loop can access the elements within the sequence. Python usage of for loops are mostly used when you have a block of code which you want to repeat a fixed number of times. The Python for…

Python loops are used to execute a block of code repeatedly. The Python while loop is a basic loop structure and the while loop runs until the condition is met and evaluated to True, and then execute the program block. The while loop is validated at the beginning of the…

Python dictionaries are a collection of changeable indexed, and not ordered elements. Similar to the Python sets, dictionaries us the curly brackets, but they contain keys and values. A Python dictionary is a mapping of unique keys to values, which are mutable. Mutable means that the Python dictionaries are able…

Python sets are a data structure in Python that are not indexed or ordered, and are written with curly brackets ( { } ).  Python sets offer a major advantage of being a highly optimized method for validating whether an element is within in the set. The hash table is…
