Python How To Program Pt 3
In 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
I just made a mistake speaking wise. Sorry about that. It’s part 3
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.
