I found this syntax for printing prime numbers and l am quite confused. I would like this community to clarify Question: Nums = range(1,60) def is_prime(Nums): for x in range(2, Nums): if (Nums%x) ==0: return False return True prime_numbers = list(filter(is_prime,Nums)) Print(prime_numbers) With the for x in range(2, Nums) syntax, l expect an error to …
Why does division "/" and floored division "//" operators in python gives different results for divisions with a remainder = 0? Question: When dividing somewhat large integers with numbers that divides them, I get different results from division / and floored division //. for instance: In [1]: a = 123456789012345678 In [2]: int(a/2) Out[2]: 61728394506172840 …
How to set a number of loop 'for' as a parameter of a function in python to find all the possibility to cut a period in n parts? Question: Here is a ugly code to find all the possibilities to cut a period in 5 parts. Is there a possibility to create a function which …
How can generate n numbers in the interval [a,b] that their summation doesn't exceed k in Python? Question: Let me I from the question in an easy way: I usually have about k=3000€ per month. This month had n=26 working days (in July as you see in the following picture), and generally, I work something …
What's the mathematical reason behind Python choosing to round integer division toward negative infinity? Question: I know Python // rounds towards negative infinity and in C++ / is truncating, rounding towards 0. And here’s what I know so far: |remainder| -12 / 10 = -1, – 2 // C++ -12 // 10 = -2, + …
What is the reason for difference between integer division and float to int conversion in python? Question: I have recently noticed that int() rounds a float towards 0, while integer division rounds a float towards its floor. for instance: -7 // 2 == -4 int(-7/2) == -3 I have read the documentation which specifies: class …
Why does integer division round down in many scripting languages? Question: In the languages I have tested, – (x div y ) is not equal to -x div y; I have tested // in Python, / in Ruby, div in Perl 6; C has a similar behavior. That behavior is usually according to spec, since …
Floor division with negative number Question: The expression 6 // 4 yields 1, where floor division produces the whole number after dividing a number. But with a negative number, why does -6 // 4 return -2? Asked By: Naz Islam || Source Answers: The // operator explicitly floors the result. Quoting the Binary arithmetic operations …
In Python, what is a good way to round towards zero in integer division? Question: 1/2 gives 0 as it should. However, -1/2 gives -1 , but I want it to round towards 0 (i.e. I want -1/2 to be 0), regardless of whether it’s positive or negative. What is the best way to do …
Integer division & modulo operation with negative operands in Python Question: Questions arise when I type in these expressions to Python 3.3.0 -10 // 3 # -4 -10 % 3 # 2 10 // -3 # -4 10 % -3 # -2 -10 // -3 # 3 It appears as though it takes the approximate …
