Why the output of 1%2 is 1 in python
Print(1%2) Output: 1 Why shouldn't be 0 ??? Can someone explain

Hi Mohammad!
1 % 2 is not 0 because 1 / 2 = 0.5 and 0.5 is not a whole number. If the result of any division isn‘t a whole number then there is a remainder, thats why you have a comma in 0.5.
So I give you some examples of Modulo:
7 % 3 means how many 3‘s you have in 7 and what remains:
So 7 = 2 * 3 + 1 and what comes after the (+) is the remainder. Therefore 1 is the remainder here.
3 % 4 means how many 4‘s do you have in 3 and what remains:
3 = 0 * 4 + 3 so 3 is the remainder.
1 % 2 means how many 2‘s you have in 1 and what remains:
1 = 0 * 2 + 1 so 1 is the remainder thats why 1 % 2 = 1.

% is the modulo operator, it give the remainder of an integer division.
How often does 2 go in one? 0
So what remains? 1

Quite simply, this operator is called modulo which returns the remainder of a division: For instance, 9 divided by 4 equals 2 but it remains 1. Here, 9 / 4 = 2 and 9 % 4 = 1.

Think of it as if I asked you what's REMAINDER after dividing APPLES by 4 people. That's the purpose of this division process, so there's no need to look at anything other than a GREEN apple.
In your example: 1 divided by 2 gives 0 but it remains 1 (1 % 2 == 1)
So the modulo operation can be calculated using this equation:
===================
a % b = a - floor(a / b) * b
===================
▪️ floor(a / b) represents the number of times you can divide a by b.
▪️ floor(a / b) * b is the amount that was successfully shared entirely.
▪️ The total (a) minus what was shared equals the remainder of the division.
Applied to your example, this gives:
1 % 2 = 1 - floor(1/2) * 2 = 1
+ 4
% is the module operator,
it always give the remainder of an division.

Hi Mohammad Esmail Qasimi
You put it so well... How often 2(divisor) goes into 1(dividend) is 0 (quotient)... 1//2 would return this... 1%2 on the other hand returns the remainder, ergo, 1-0...

Oh you are going to be stubborn. 😔
New example:
You and a friend (= 2 people) want to go to the zoo. You have 1 zoo entry ticket. You try to share 1 between 2 but you can't do it without fractions (or decimals called float). You each get 0 tickets, the remaining tickets are 1.
1%2=1.

You can remember it like this...
a%b = a if a<b
Otherwise it's remainder of a/b

Quantum what likely hood is it that you are right & all these other programmers are wrong?
Could it be a chance for you to learn, or are you going to be stubborn (and wrong)?
Example using words: you have 7 grapes and 2 friends, you want to give each person an even share, how many are left?
7%3=1
because 7 split into 3 gives 3 groups of 2 with 1 remainder.
Could you cut the last grape and share it? Yes, but not without using fractions (or decimals called float in programming), so keeping whole numbers (called integers in programming) is the remainder result of modulo.

See if i multiple 2 by 0.5, it's equal to 1 right?
So in floats there is an option call round-off. If the number after "." Is greater than or equal to 5 so we remove that number and increase it's left sided number by 1.
If i round-off 0.5 that will be equal to 1👍

It's simple, a%2 :
1 if the number is odd else 0 if number is even

2%2 is like the words "what is the remainder of 2 divided by 2" = 0 (no remainder)
1%2 is like the words "what is the remainder of 1 divided by 2" = 1. (because 2 doesn't go into 1, but there is 1 remainder.)
Modulo result is the remainder.

Hello team,
I am new here. Who is also new here to team up with me.

In Python, the `%` operator is the modulo operator, which returns the remainder of the division between two numbers. In the case of `1 % 2`, the division `1 / 2` has a quotient of 0 with a remainder of 1.
When calculating `1 % 2`, the remainder is computed, not the quotient. Since the dividend (1) is smaller than the divisor (2), the remainder is equal to the dividend itself. Therefore, the output of `1 % 2` is 1.
To illustrate further:
print(1 % 2) # Output: 1
Here, `1` is the remainder obtained when dividing `1` by `2`, and thus it is the result of the modulo operation. If the dividend were larger than or equal to the divisor, the remainder would be different. For example, `5 % 2` would be `1` because `5` divided by `2` equals `2` with a remainder of `1`.

As you said how often 2 goes to 1 is 0
So the answer should be 0 ???
Sorry if i am dumb
Like 3%2 is 1 bcz 2 goes 3 once and the remaining is 1.

Because Modulo (%) gives the remainder
