However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300? The solution is an array! An array can hold many values under a single name, and you can access the values by referring to an index number. Unlike arrays in some languages, Python lists are very flexible: Can contain duplicate items Mutable: items can be modified, replaced, or removed Ordered: maintains the order in which items are added Index-based: items are accessed using their position (starting from 0) Can store mixed data types Using itertools for arbitrary number of nested loops of different ranges with dependencies? How to print the console to a text file AFTER the program finishes (Python)?. High speed is retained by preferring “vectorized” building blocks over the use of for-loops and generators which incur interpreter overhead. The main types are For loops (counting through items) and While loops (based on conditions).
