Python How To Program Pt 3

PythonIn this video I cover how to use the list data types in Python (tuples, lists, dictionary’s).

I also review and introduce the While Loop, If then Elif, and a bunch of tricks with Python. All of the code from the video follows the video on this page. If you didn’t watch part 1 of this tutorial watch it here: Python How To Program

If you have any questions or comments, leave them in the comment section below.

NOTE: At the end of the video, I say I don’t know the topic of the next video. It will be on Object Oriented Programming with Python.

All of The Code From the Video

# Whats a tuple? An Immutable List

tupleEx = (‘Derek’, 35, ‘Pittsburgh’, ‘PA’)

for i in tupleEx:
print(i)

print(“First element in the tuple is “, tupleEx[0])

# That’s it tuples don’t have methods

listEx = [‘Derek’, 35, ‘Pittsburgh’, ‘PA’]

for i in listEx:
print(i)

listEx.append(“Joy”)

print(listEx)
print(listEx[4])

listEx.remove(“Joy”)

print(listEx)

listEx.remove(listEx[3])

print(listEx)

listEx.insert(2, ‘PA’)

print(listEx)

listEx2 = [‘f’, ‘e’, ‘c’, ‘d’, ‘a’, ‘b’]

listEx2.sort()

print(listEx2)

listEx2.reverse()

print(listEx2)

listEx3 = [
[‘a’,’b’,’c’],
[‘d’,’e’,’f’],
[‘g’,’h’,’i’],
]

print(listEx3[2][1])

# Dictionary’s are immutable variables that have a key associated with values

dictEx = ({“Age”:35, “Height”:”6’3″, “Weight”:169})

print(dictEx)

print(dictEx.get(“Height”))

print(dictEx.items())

print(dictEx.values())

dictEx.pop(“Height”)

print(dictEx)

# while loop time

a, b = 1, 11

while a < b:
print(a)
a += 1

for x in [1,2,3,4]:
print(x)

listCycle = [1,2,3,4]

listCycle[:] = range(1,201)

for i in listCycle : print(i)

for i in listCycle :
if (i%2) == 0:
continue
elif (i == 101):
break
else:
print(i)

    The link says pt3 but in the vid you call it pt 4? can you clear this up for us or did you skip pt3?.
    -confused
    Thanks

    The last bit of code doesn’t seem to be working properly for me. The part that counts up to 200 but only the odd numbers, when I run the code it still just runs through all the odd and even numbers.
