In Python 3.9.0 or greater we can merge dictionaries using `|`:
d1 = {"name": "Alex", "age": 25}
d2 = {"name": "Alex", "city": "New York"}
merged_dict = d1 | d2

On the last tip it would be much faster to use a set instead of a list. Sets have constant lookup time but lists have O(n) lookup time.

Superb content. I am a C++ programmer, but since 2019 have been dabbling with python. Being pythonic is actually what I look for as of now. Thanks.
@vitalimueller6209
Nr.3 you can also do:
from operator import itemgetter
sorted_data = sorted(data, key=itemgetter('age'))
@mei2654
2:59 you can preserve order with the help of sorted function example: my_list = [1, 2, 2, 3, 4, 5, 6, 7, 7 , 9, 8] sorted(set(my_list), key= lambda x: my_list.index(x)) >>> [1, 2, 3, 4, 5, 6, 7, 9, 8]

I thought this would be something that would go way over my head but, as some that recently started learning python, this was really valuable!
@schedarr
That is absolutely golden video. Extremaly useful tricks that will make your life way much easier. I've already used 10 out of 11 but still it's nice refresher.
@eminm6383
I almost don't know any python, but I was able to comprehend 80% of the content. Amazing simple explanation. Thanks.
@jordangl1
Your videos are by far the most concise and easiest to assimilate compared to every other YT Python teacher (to me). Thanks for taking the time. Good stuff
@alignandevolve
An alternative of TIP 10:
if you have two dictionaries you can join them using | operator.
d1={'one' : 1, 'two':2}
d2={'three':3}
d3=d1|d2
print(d3)
output: {'one': 1, 'two': 2, 'three': 3}
@jth5726
dude, I've been doing a programming course 12 weeks, I feel like f-strings are something we should have been taught immediately, why am I only learning it through you
@stevenwilson5556
The Squares example.. here's Python code: squares = [i*i for i in range(15)] print(squares) Here's the R code: x = 1:14; x^2 Python 48 characters, 2 lines R 13 characters, 1 line Advantage: R.
@TheSuperUser
Great video. Please make more of these quick tips for comparisons of "beginner" python code vs experienced developer idioms
@etgaming6063
If you aren't speeding up your videos during your scripting then you are a REALLY FAST typer, like holy crap. IDK how you can type those lists in under a second, that is crazy to me.
@saurabhjain507
I love how you explain with simplicity. Great content.
@Arson_Oakwood
I'm amazed at how there are beginner programmers, who never read basic tutorial in official documentation, and then watch similar videos, thinking they are learning advanced concepts.
@Kinos141
Finally, how to do strings properly. I love using something like that in c#, and I'm glad it's on other languages like python.
@bashvim
What keyboard shortcut are you using run the python file in the Output tab below?
