Lists with if statements and loops

Summary

## Instruction

Good. Using square brackets, we can also assign new values to specific list elements.

# define a list
companies = ['Royal Dutch Shell', 'BP', 'Total', 'Volkswagen', 'Glencore Xstrata', 'Gazprom']

# ranking changes
companies[5] = 'E.ON'


We found out that E.ON now has a higher revenue than Gazprom, so we change the sixth element (remember, its index is 5) to E.ON. Gazprom is out of the game!

## Exercise

Correct the mistake in your data. The third day's water level should be 693. Print the contents of the changed list.

### Stuck? Here's a hint!

The third day has an index of 2.
