Bitwise, the python operator that you probably don't use.

Here is some information on bitwise operators in python:

use these operators if you want to confuse your colleagues and look smart haha

[alioudiouf]

def is_odd_fct(n):
return n & 1


def is_even_fct(n):
return 1 - (n & 1)


Or compute a variable (let say is_even_var), for a given n:
is_even_var = 1 - is_odd_fct(n)

I use it quite often, for masking.

# df is a pandas DataFrame
filtered_df = df[ (df[a_col>3) & (df[another_col] == "some_string") ]

More rarely:
# arr is a numpy array
a_mask = (arr>1) & (arr<15)

Your videos motivate me each day to gain some more syntax, try some more problems(though I don't know much as you to solve them all).

where is link to learn more about bitwise operators ?,
good video btw

[PedroAnacletoOficial]

dude, you're channel is absolutely sensational! please keep it

Do you have any advice on what I can learn while driving in the car? I want to get better at programming and data science. So any education in either of those fields is good with me. My commute is about 1.5 hours driving.

Do you have any recommendations for good feature engineering books?

It probably could be done like this:
return {0:b}.format(n).endswith(0)

[riccardoronco]

to check for speed you could show a for next loop to test all numbers from 1 to 100, 000, 000 and see the difference :)

[blackraven]

def test_for_odd(n): # a smaller format
return bool(n & 1)

can you do similar videos on other bitwise operators, giving examples of how to use them. I never knew you could use & to determine whether number is odd or even for example, seems like a logical thing now that I think about it, but bits are so weird I never connected them to real life thing. it also seems like it would be knowledge applicable onto quantum computing, where basically all programming boils down to applying gates to qubits, which is like, applying bitwise operators to bits

cannot put into words how proud of my self I was when I figured out you could use hadamard gate to make a coin toss game ><

[frecio]

Could you instead do:
def is_even_ 2(n):
>> return not n & 1
???

[jaadow]

How about return True or False rather than 1 or 0
def is_even(n):
return not ( n & 1)

[gurpreetchahal]

Wowhhh that bass is insan 😍 anyone noticed?

[PaulSmith-zsje]

# go fully bitwise

IsEven = lambda n: ~n & 1

def is_even(n):
return ~n & 1

[benverret]

def is_even(n):
return not n & 1

[lucasrodrigues]

Shouldn't the first function be:
def is_even(n):
if n % 2 == 0:
return 0
return 1
