Dictionaries in Python - Advanced Python 03 - Programming Tutorial

You guys watch each other tutorials before creating one? You folks all show the same methods!! Watch one and you watched all, right?? Waist of my time.

thank u man

Helpful and Informative

I'm never naming my dictionary as "myDict"

🙂

for those new to this topic like me

in the example 'USA': 'Washington DC' - USA is the key and Washington DC is the value

May seem obvious but realising this made me understand this easier and hopefully you too

you explore parts of topics that a lot of others do not.
much appreciations for that

It was really helpful, thank you.

I have a table and I want to assign my keys as a Table Headers. Table has 50 columns (keys) and 100 rows.

So when I use popitem() it returns me the key and value of that dictionary( which was under curly braces { } ) as a tuple ( (... ...) ). May I please know what is the reason behind it or it is by definition/ trivial

Thanks for the great video content!

mydik = {'size': ['small', 'medium', 'large'], 'color':['brown', 'red', 'black'], 'weather':['warm','cold']}

print(mydik['size'][0])
print(mydik['color'][0])
print(mydik['weather'][1])

Awesome Awesome Awesome

mydict :p

2.
s=input()
s=s.split()
h=[]
for i in s:
h.append (i[::-1])
k=" ".join(h)
print("obrnuto", k)
a=[]
for j in h:
a.append(j.count("a"))

r=[]
for y in range (len(s)):
l=a.index(max(a))
r.append(s.pop(l))
a.pop(l)
print(r) rijeci po broju slova a

1.
s=input()
brojrijeci=s.count(" ")+1
print(brojrijeci)
s=s.replace("a","")
print(s)
r={}
s=s.split()
for i in s:
r.update ({ i:len (i) })
print(r)

Can you add a key to a dictionary with multiple values AND multiple value types? i.e. "Variable1": "MyName", 14, [A, B, C]
Awesome tutorial!

Excellent video
Now I think I can deal with Dict:

my_dict = {"content": something, "length": None}
instance = my_dict.pop("content")
my_dict["length"] = scan(instance, in="cm")
if my_dict["length"] > 12:
yup()
else:
nope()

Kudos to you, the way you applied this tutorial helped me understand how the other concept works as well.

THANK YOU!

how to add a element at particular index?

From 3.7+ dictionaries are now "insertion ordered"

Thanks so much for the useful video.

I was listening to this one my speakers at max volume and just kept hearing mydi**

Thank you

which IDE do you use?

You go so far the tutorial is worthless.

man love this videos , god bless you

Excellent!

Это лучшее видео на свете

Sir very nice video. I have one question , how to print specific key value in a dictionary. Without entering its name in code. We should get the output as - Enter the product name ( some key)
- it's value should come as output. Please help me sir.

Dictionaries: test your comprehension:
- how to initialize a dictionary? (2 ways)
- how to delete by key? (2 ways)
- how to delete the last inserted key? (only as of python 3.7)
- how to iterate keys, values and elements?
- how to copy a dictionary? (2 ways)
- can a tuple be a dictionary key? why?

Change the name for this video series. This is beginner stuff. Don't
lie to people by calling it advanced. You lose your credibility from
the start when you LIE to people right from the start.

Sir I Ask One Questions Please....??

In this 21 lecture...a to z python is completed....Basic to advance everthing ??? Say me sir please

Quit Interesting

The t is sometimes missing in mydict...

you wrap up on everything, you are a legend

This is a great series to speed through for my upcoming interview!

a little trick: reverse dictionary's key and value

mydict = dict(a=0, b=1, c=2)
print(mydict)
reversed_mydict = {v:k for k, v in mydict.items()}
print(reversed_mydict)

{'a': 0, 'b': 1, 'c': 2}
{0: 'a', 1: 'b', 2: 'c'}


Use with caution. When you have same value in the dictionary, the reversed dictionary's value may be overwritten.
mydict = dict(a=0, b=1, c=1) # both b and c have the same value 1
print(mydict)
reversed_mydict = {v:k for k, v in mydict.items()}
print(reversed_mydict)

{'a': 0, 'b': 1, 'c': 1}
{0: 'a', 1: 'c'}

hahaah..thank you

What is mutable?

Hi, I just started coding and I was wondering what platform you're using for your code. I've been coding through IDLE but it's a lot less easier to create big functions and see the outputs clearly, so I was just wondering

Hello, I'm recently starting using VS Code for my python projects, how are you able to run the code on the output section without running the whole file address, I'm having trouble on that. Thank you.

Im just starting to learn Python. I just wanted you to know how insightful and helpful your videos are. I have a question - I have a large file of data organized in alphabetical order. what is an efficient way to parse out ONLY USA data. the file is a .txt file. any comments would be appreciated, I will continue with your site thank you

Thanks for this wonderful video, you explained a very simple way. I have one query related to a python dictionary is it possible we can store excel data into a python dictionary and perform some CRUD operation on it.
