Introduction
List basics
Lists with if statements and loops
Lists in functions
Instruction
Excellent. Elements in a list are indexed (numbered):
And you can get a specific item from a list in the following way:
# define a list companies = ['Royal Dutch Shell', 'BP', 'Total', 'Volkswagen', 'Glencore Xstrata', 'Gazprom'] # access Volkswagen print(companies[3])
We provide a list name (companies), followed by a pair of square brackets. Inside, we put the index (number) of the specific element we want to retrieve. This way, we can access any element in the list.
List indices start at 0, not 1. In other words, companies[0] is the first element, and companies[3] is the fourth element. This is a common mistake among beginners, so watch out!
Exercise
What was the water level on the third day in your previously defined list? Print the right list element.
Stuck? Here's a hint!
Remember that the third element has an index of 2.
