List Methods and Functions in Python: zip(), range(), .join() - Part 3 Series A
This is the final of three videos where I go over the basics of how to work with lists in Python. I am not an expert when it comes to Python, but I know that teaching a subject helps solidify the information learned about.
This is Series A
Series A = 1
Series B = 2
Each series is intended to be better than the last because of all the practice I'll get in creating them.

Lists Part 3
a,b,c, *remainder = [1,2,3,4,5,6,7,8]
print(a)
print(b)
print(c)
print(remainder)
Reverse with -1
.reverse() or [::-1] or -x
list() with range(0,100,-1)
range in steps?
.join()
zip()
unpacking lists (need new list for this)
1. Reverse the order of the below lists
['Over', 'Blue', 'Tyrion', 'Sound', 'Cloud_9', 'Mug', 1, 2, 3]
['road', 'brick', 'yellow','the','Down']
['(^_^)', '(*_*)', "('-')", "('')_(*_*)_('')"]
[66,44,22,'World','Hello']
[1,2,3,4,5,6,7,8]
['Few', 'Yellow', True, 101, False, 'Egg', 'Easter', 'Banana']
------------------------------------------------------------------------------------------------------
2. Convert the following into a list
('Over', 'Blue', 'Tyrion', 'Sound', 'Cloud_9', 'Mug', 1, 2, 3)
{'road', 'brick', 'yellow','the','Down'}
{'(^_^)', '(*_*)', "('-')", "('')_(*_*)_('')"}
{66,44,22,'World','Hello'}
(1,2,3,4,5,6,7,8)
('Few', 'Yellow', True, 101, False, 'Egg', 'Easter', 'Banana')
range(100)
range(1,100, 2)
range(1,100, -1)
range(1, 100, -2)
------------------------------------------------------------------------------------------------------
3. What does range() do? Try the below.
for i in range(100):
print(i)
------------------------------------------------------------------------------------------------------
4. Can you use .join() with integers and strings?
What about integers and booleans?
What about just integers?
oscar = ['h', 'o', 'h', 'o', 'h', 'o']
What does ' '.join(oscar) do - if you print it?
------------------------------------------------------------------------------------------------------
5. zip() How can you use zip() with the below lists? Remember list() will turn the values into a list.
blue = ['Over', 'Blue', 'Tyrion', 'Sound', 'Cloud_9', 'Mug', 1, 2, 3]
yellow = ['road', 'brick', 'yellow','the','Down']
green = ['(^_^)', '(*_*)', "('-')", "('')_(*_*)_('')"]
red = [66,44,22,'World','Hello']
pink = list((1,2,3,4,5,6,7,8))
final = list(('Few', 'Yellow', True, 101, False, 'Egg', 'Easter', 'Banana'))
trial = list(range(100))
epic = range(1,100, 2)
transform = list(range(1,100, -1))
yep = list(range(1, 100, -2))
Example:
epic = range(1,100, 2)
my_list = range(1, 100, 2)
together = list(zip(epic, my_list))
print(together)
tip rather than list(), you can also use tuple()
2.1 Zip each of the variables above together in sets of 2, 3, 4, and so on. Can you zip all of the variables?
------------------------------------------------------------------------------------------------------
3. Use the lists above and unpack them.
How could you unpack each list?
Do you need a *, or a,b,c,d?
How many positions are held within each list?
How many variables can be assigned to each list?
------------------------------------------------------------------------------------------------------
4. Additional Practice - Delete all of the lists above and create your own lists to practice with.
