Learn Python Programming - 18 - Logical AND OR NOT

[@InFamousCzr]

That image is confusing maybe it's best explained like this. "AND" = both have to be true to be true. True and true = true True and false = false False and true = false False and false = false "OR" = just one has to be true to return true. True or true = true True or false = true False or True = true False or false = false "NOT" = opposite of each other Not true = false Not false = true In case someone watching this still doesn't get it.

Thanks, i screen shot this for quick reference

U r a hero

[@Tuvis_Official]

I came back to the video just to read this comment

[@pnfitness7847]

You have a natural gift and ability to explain programming in ways that are so understandable! You made something I was confused on so simple. Thank you!

[@MR_MAGUIRE.]

Same here 😁😁👍

[@yashkulkarni6421]

No bro. He was gone through that situation and learned from that n thats he is able to explain that things.😇

[@williambuchanan9621]

Your an amazing teacher. Straight up. Pizza and poison, so simple yet so perfect.

[@KidsLearnHTML]

15:08 Thank you for clarifying the "what's necessary" stuff with real life. It's much appreciated.

[@Zen-rw2fz]

i was so confused about this last month and without even doing anything this sounds too simple

[@gore9341]

thank you SO much man! I was struggling so hard with the whole "not not false and true and false" junk. Your video summed it up perfectly for me. Mad respect my man!!

[@antonkorolev8059]

AMAZING!! Im taking free MIT Python courses - and you explain it perfectly ! Thank you

[@the_professional2558]

Hi CP, thank you for putting in the work! I use "youtube lectures" like yours to expand my knowledge in certain areas next to my usual studies. Very well done and easy to follow. Keep it up! Greetings from Germany :)

[@043mehdi]

hello from Germany too :D

[@JevvyMedia]

This video helped me a lot, especially with the real-life examples. Thank you so much.

[@juwu3447]

Like the way you are teaching! Savior of the day~

[@MR_MAGUIRE.]

14:12 It's False OR True, you said False AND True.

[@TheZangetsutensu]

3:55 slick move there fella..:)

[@shenelldixon-transformyour4237]

wow he is really good at teaching.

[@abufaya4155]

I'm enjoying it!!!!

[@jaitelyg]

this was helpful and nice teacher True

[@olgafridzon1705]

Dude, you're amazing!!!

[@basiert7701]

Alot of people are giving up

[@drbabbers]

Superb video thank you!

[@derrickandchelseamcfall4848]

actually 'True or poision' worked because as soon as python evaluated True, the or statement evaluates to True. If you would have done poision or True you would have gotten a traceback error. It's called short-circuiting. If the first part of the or statement is True it doesn't even evaluate the second part because the statement is True by definition of 'or'.

[@derrik-bosse]

I am still yet to see a majority of this stuff on your website!

[@mohamedmukhtar1600]

import turtle my_turtle = turtle.Turtle() my_turtle.speed (0) # Lesson learnt is that, I have called the Turtle fuction in the defined fuction and eachtime the system run it as part of the defined fuction. def sqy(length, angle): my_turtle.forward(length) my_turtle.left(angle) my_turtle.forward(length) my_turtle.left(angle) my_turtle.forward(length) my_turtle.left(angle) my_turtle.forward(length) my_turtle.forward(length) for i in range(101): sqy(50,90) my_turtle.right(11) #my_turtle = turtle.Turtle() #my_turtle.forward(100)

[@verylongchannelhandle]

Qazi,where is the link to the table?

[@Henki2]

def password_1(): print('please enter username and password') tries = 0 while True: username = input() password = input() if username == 'henki' and password == 'pass': print('access granted') elif tries >= 2: print('access denied') break if tries < 2: tries = tries + 1 password_1()

[@offzone1199]

Hey man! I wanted to say throughout these series this has worked out for me but some of the things like slicing strings and == = != didn't work is it because you need terminal for those type of stuff . And also idk how to search for files like that, i found idle when i located the file of python. CAn you please help on how to get pip,terminal and stuff like that and also why soe of the things doesn't work? Thank You ( I watched like 8+ episodes of these series in my first day)

[@saadmansakib9002]

this and or actually means bulean multiplication and addition where true is 1 and false is 0

[@shaikaftabahmed9666]

thanks bro tomorrow i have cs exam .......hope it helps

[@aabidmz5706]

How did it gave output for poision example......

[@preetamsaha1744]

its showing the name true and false are not defined.i cant do this this operations please help me .i m using in windows this true and false are appearing in black color but in u r video its in orange

[@combatxhoop7069]

its case sensitive, Capitalize the first letter like True and False

[@philsgaming4853]

write it like this True or False

[@combatxhoop7069]

Your site just kinda put us in the video of How i Leaned to Code in less then 2 months and it doesnt really enroll us how to enroll

[@kurdobakur7047]

use_input = [('What', 'WP'), ('is', 'VBZ'), ('your', 'PRP$'), ('name', 'NN'), ('?', '.')] x = ('What', 'WP') y = ('name', 'NN') z = ('age', 'NN') z and y in use_input >>> True How could that be? and what can I do to make sure it returns false when one of the variables is not in the use_input?

[@roxazzino3115]

why does not(True or True or False and (True and False)) give back False? i was thinking like that : True or True or False = True | not(True and (True and False)) True and False = False | not(True and(False)) True and False = False | not(False) = True why isn't it correct?

[@silverzero9524]

bracket comes first. not(True or True or False and False) i.e not( True or False) not(True) = False

[@roxazzino3115]

ah ok thanks

[@bhumiraksmith4656]

not(True or False or True and ( True and False)) # Break it down # you know what i mean if you learn math True or False or True and False # Break it down again True or False # This is the process in which the comp calculate = not(True) = False # :D

[@vomCzumHzumRIS]

throwback to Wittgenstein

[@miguelsalvador28]

Why is it I always forget the most basic parts of python smh, and thanks!

[@pavithiranflash3677]

Guys, i had this ques. when i was watching python Tutorial! not(True or True or False and False) Does AND executes first before OR...?? if that happens it leads to : not( True or False) not(True) False Whats actually happening their..??? Thx for feedBack.. :)

[@yushuot]

I couldn't get it as well. Because if like in math times and divide is at the same priority then you will do it from the front to the back but here is like if you don't do the "and" first you will get the exact opposite. So I also guessed that "and" has the priority over "or"

[@Shams_Defi]

Yes first you need to count AND then after that count OR

[@adidediu8278]

First of all the parentheses are solved then it is made the whole calculation

[@husseinalwash7707]

Thanx man

[@javinp4105]

You seem a bit out of it my friend! Sick?? Like the video :)

[@jade8144]

February 2019?

[@hamzaelzarw160]

how can i make the speed of the turtle faster than zero

[@s000sdas]

import random bools = [True, False] johnny = { 'math_homework' : random.choice(bools), 'pizza' : random.choice(bools)} if johnny['math_homework'] != True and johnny['pizza'] == True: print("johhny likes pizza but dislikes math")elif johnny['math_homework'] == True and johnny['pizza'] == True: print("johnny likes both pizza and math")else: print("johhny likes math but dislikes pizza")

[@r3m4k49]

I love you bro

[@sunzalea3257]

yes i like posion and pizza

[@v2nny]

Damn its that simple, my book makes it too complicated :[

[@opssheesh]

guys! can anyone give me tips on how i can learn to type so fast even when i have to type symbols and numbers?

[@043mehdi]

typing.io is your friend. and lots of practice, never ever look down on your keyboard, you will be superfast in no time. Good luck

[@97javaid]

it can be more simple, if we consider False = 0 & True = 1 AND = * OR = + A B A AND B A OR B Not A 0 0 0 0 1 0 1 0 1 1 1 0 0 1 0 1 1 1 1 1 it's make more sense ??

[@beratcapcak5784]

yeah now high school math is begining to make some sense

[@ronitgummadi9167]

why did you flex on your income

[@efishaya7558]

tnx!!!!!!

[@rayylion6166]

lol i was like Spongebob_hours_worked = 40

[@pulokahmed5760]

i don't understand why the result is False here: >>> not(True or False or True and (True and False)) False it should be True because: >>> not(True or False or True) False >>> not(True and False) True >>> not(True and False) True ????????

[@hhinfosystemspvt.ltd.2705]

IT SOLVES IT IN THIS WAY: 1.not(True or False or True and(True and False)) 2.not(True or False or True and (False)),,,it first solves the bracket 3.not(True or False or True and False) 4.not(True or False or False),,,,,,,it solves and before or 5.not(True or False) 6.not(True) 7.False

[@Shams_Defi]

In programming there is something called operator preference, just like in mathematics first you need to count multiplication and then addition and subtraction, in programming language you count AND before OR,

[@sharjilsharma424]

u r so confused bro
