# Almost six years later, and I'm still learning how to master

# Use the enumerate() function to loop through a list, using
# only two lines of code; one for the for-index enumerate()
# function and the other for the 'print' statement.

name_list=['John','Bob','Rob','Tom']

# Here is a simple for-loop that will loop through the name_list
# values starting with index 0, followed by index 1 and then
# index 2, and finally index 3.

for index in name_list:
    print(index)

# The for-loop example above is fine, but it has its limitations
# when it comes to multi indexing through a tuple or list alike.
# With the enumerate() function, such things are possible.
# Try these enumerate() function Python program examples
# below and see what happens when you experiment with them.

for index,name in enumerate(name_list):
    print(index)

for index,name in enumerate(name_list):
    print(name)

for index,name in enumerate(name_list):
    print(index,name)

for index,name in enumerate(name_list,start=1):
    print(index,name)

name=['John','Bob','Rob','Tom']
pet=['Dog','Cat','Bird','Fish']
computer=['Desktop','Laptop','Cellphone','Notebook']

# Note: the zip() function only goes to the shortest length
# in a multi list. However, you can simply keep them the
# same size such as the list examples above, which shows
# three lists called name, pet and computer. Each list has
# four values in them. This way, every value gets called inside
# one, single 'print' statement. Try these different examples
# below. Note: you can rename the words 'index1, index2 and
# index3' to any names you wish. You can also rename the
# name variable if you like.

for index1,index2,index3 in zip(name,pet,computer):
    print(index1)

for index1,index2,index3 in zip(name,pet,computer):
    print(index2)

for index1,index2,index3 in zip(name,pet,computer):
    print(index3)

# Let's try some fun experiment examples with some of what
# we've learned so far about the enumerate() function. Let's
# create a program that uses a sentence for each value in the
# fun_list1,  fun_list2 and fun_list3 lists. Let's use the f' format
# to make string concatenations much easier to create.

fun_list1=['John','Bob','Rob','Tom']
fun_list2=['Dog','Cat','Bird','Fish']
fun_list3=['Desktop','Laptop','Cellphone','Notebook']

for index,name in enumerate(fun_list1):
    print(f"My name is {name}. I'm the value from the fun_list1, position {index}")

for index,name in enumerate(fun_list2):
    print(f"I am a {name}. I'm the value from the fun_list2, position {index}")

for index,name in enumerate(fun_list3):
    print(f"I am a {name}. I'm the value from the fun_list3, position {index}")

# These enumerate() function examples are great, but let's beef it up just a lot
# more with the zip() function, so we can create complex actions with all our
# fun_lists combined into complete, separate sentences, just simply using two
# lines of code. See what happens when you type and execute/run this Python
# program example below:

for list1,list2,list3 in zip(fun_list1,fun_list2,fun_list3):
    print(f"My name is {list1} and I have a {list2} picture on my {list3} screen.")

# The zip() function is very useful, but it can only reach as far as its shortest
# list length. That means, if you have two, three or more lists, the shortest list
# out of the three or more lists values will be cut off from the rest if one or more
# lists have extra values inside them. To avoid this from occurring, make all your
# lists the same size in each of their values. take a look at the example below:

fun_list1=['John','Bob','Rob','Tom'] # four values
fun_list2=['Dog','Cat','Bird','Fish'] # four values
fun_list3=['Desktop','Laptop','Cellphone','Notebook'] # four values

# The zip() function is sometimes better than a simple for-loop or a simple
# enumerate() function, in that it uses less lines of code and it can also achieve
# a far better programming style approach over program code redundancy on
# the programmer's part.

# Let's try one more example to prove this to be true. let's create another
# fun_list, zip() function Python program example. Type and execute/run
# this Python program below and see what happens with the output.

fun_list1=['John','Bob','Rob','Tom']
fun_list2=['Dog','Cat','Bird','Fish']
fun_list3=['Desktop','Laptop','Cellphone','Notebook']
fun_list4=['loves my','hates my','found my','lost my']
fun_list5=['fed his',"didn't feed his",'plays with his',"doesn't play with his"]

for list1,list2,list3,list4,list5 in zip(fun_list1,fun_list2,fun_list3,fun_list4,fun_list5):
    print(f'{list1} {list4} {list3} and {list5} {list2}.')

# Well, I think we pretty much learned what the enumerate() and zip() functions
# do. Now, it's practice, practice, practice and more practice, practice, practice...
