Found you on Udemy. Your videos are great. They're not too lengthy, and are very easy to follow.
Thank you for making these!

Really enjoy your videos! They are not too long and really clear. Ive watched several other beginner tutorials and none have been as easy to follow as yours. Thanks again for all your hard work making these!

Hi,
First of all, I want send a lot of gratitude to your door.
I just started out learning Python and your videos have been a great help.
I do this stuff on the side window with the video playing and it helps me a lot.


But this time around, I can't seem to make it work.
As you did, I created a list first and then typed in the dictionary. But then when I call the dictionary, output shows me the list.


Like so:
students_age=['a', 10, 'b', 11, 'c', 12]

students_age
Out[3]: ['a', 10, 'b', 11, 'c', 12]
studens_age={"a":10, "b":11, "c":12}
students_age
Out[5]: ['a', 10, 'b', 11, 'c', 12]


When I try with a different name though, it works. But when I call the previous dictionary, output again shows me the list.


Like so:
students_age=['a', 10, 'b', 11, 'c', 12]
students_age
Out[3]: ['a', 10, 'b', 11, 'c', 12]
studens_age={"a":10, "b":11, "c":12}
students_age
Out[5]: ['a', 10, 'b', 11, 'c', 12]
aa={'x':1, 'y':2}
aa
Out[7]: {'x': 1, 'y': 2}
studens_age={"a":10, "b":11, "c":12}
students_age
Out[9]: ['a', 10, 'b', 11, 'c', 12]


What am I doing wrong?

And how can we add multiple values to the dictionary corresponding to one key

[kitsienkabiti]

Is there a way you can use the value to find the key it is associated too or is it only find the value from the key it is associated with??
