This question already has an answer here:
fflush(stdin) is undefiined behavior.
int fflush(FILE *ostream);
ostream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes
any unwritten data for that stream to be delivered to the host
environment to be written to the file; otherwise, the behavior is
Making a matrix in python 3 without numpy using inputs
I want to have two inputs : a,b or x,y whatever...When the user inputs say,3 5Then the shell should print a matrix with 3 rows and 5 columns also it should fill the matrix with natural numbers( number sequence starting with 1 and not 0).Example:: IN :2 2OUT:[1,2] [3,4] If your objective is only to get the output in that formatn,m=map(int,input().split())count=0for _ in range(0,n): list= while len(list) > 0 : list.pop() for i in range(count,count+m): list.append(i) count+=1 print(list) [XXX]I am going to give a try without using numpy...
Why assigning a function as variable is faster in Python
Today I observed an interesting behavior using Python.def f(): ls1 =  for x in range(1000000): ls1.append(x)%timeit f()77.2 ms ± 1.83 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)And tested a second function.def f2(): ls1 =  lsa = ls1.append for x in range(1000000): lsa(x) %timeit f2()56 ms ± 566 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)Assigning append to a variable was faster than using append inside the loop.Why the second function is faster? Because in the second function, you have the reference to the m...
Please clarify my mistake while doing the dry run
The following code is all correct but I have a doubt. While I am doing the dry run I find in my mind that it should show 2 as NOT a prime number. Someone please clarify how the code is running all good. num = 4if num > 1: for i in range(2,num): if (num % i) == 0: print(num,"is not a prime number") print(i,"times",num//i,"is",num) break else: print(num,"is a prime number")else: print(num,"is not a prime number") 2 is a prime number, but your code will shows 2 as not a prime numberHere is the fix:num = 4if num > 2: fo...
