[python] Find the division remainder of a number

How could I go about finding the division remainder of a number in Python?

For example:
If the number is 26 and divided number is 7, then the division remainder is 5.
(since 7+7+7=21 and 26-21=5.)

If you want to get quotient and remainder in one line of code (more general usecase), use:

quotient, remainder = divmod(dividend, divisor)
#or
divmod(26, 7)

Modulo would be the correct answer, but if you're doing it manually this should work.

num = input("Enter a number: ")
div = input("Enter a divisor: ")

while num >= div:
    num -= div
print num

Use the % instead of the / when you divide. This will return the remainder for you. So in your case

26 % 7 = 5

From Python 3.7, there is a new math.remainder() function:

from math import remainder
print(remainder(26,7))

Output:

-2.0  # not 5

Note, as above, it's not the same as %.

Quoting the documentation:

math.remainder(x, y)

Return the IEEE 754-style remainder of x with respect to y. For finite x and finite nonzero y, this is the difference x - n*y, where n is the closest integer to the exact value of the quotient x / y. If x / y is exactly halfway between two consecutive integers, the nearest even integer is used for n. The remainder r = remainder(x, y) thus always satisfies abs(r) <= 0.5 * abs(y).

Special cases follow IEEE 754: in particular, remainder(x, math.inf) is x for any finite x, and remainder(x, 0) and remainder(math.inf, x) raise ValueError for any non-NaN x. If the result of the remainder operation is zero, that zero will have the same sign as x.

On platforms using IEEE 754 binary floating-point, the result of this operation is always exactly representable: no rounding error is introduced.

Issue29962 describes the rationale for creating the new function.

26 % 7 (you will get remainder)

26 / 7 (you will get divisor can be float value )

26 // 7 (you will get divisor only integer value) )

We can solve this by using modulus operator (%)

26 % 7 = 5;

but 26 / 7 = 3 because it will give quotient but % operator will give remainder.

You can find remainder using modulo operator Example

a=14
b=10
print(a%b)

It will print 4

If you want to avoid modulo, you can also use a combination of the four basic operations :)

26 - (26 // 7 * 7) = 5

The remainder of a division can be discovered using the operator %:

>>> 26%7
5

In case you need both the quotient and the modulo, there's the builtin divmod function:

>>> seconds= 137
>>> minutes, seconds= divmod(seconds, 60)

If you want the remainder of your division problem, just use the actual remainder rules, just like in mathematics. Granted this won't give you a decimal output.

valone = 8
valtwo = 3
x = valone / valtwo
r = valone - (valtwo * x)
print "Answer: %s with a remainder of %s" % (x, r)

If you want to make this in a calculator format, just substitute valone = 8 with valone = int(input("Value One")). Do the same with valtwo = 3, but different vairables obviously.

you can define a function and call it remainder with 2 values like rem(number1,number2) that returns number1%number2 then create a while and set it to true then print out two inputs for your function holding number 1 and 2 then print(rem(number1,number2)
