List Element without iteration

The mylist.index(“blah”) method of a list will return the index of the first occurrence of the item “blah”: >>> [“item 1”, “blah”, “item 3”].index(“blah”) 1 >>> [“item 1”, “item 2”, “blah”].index(“blah”) 2 It will raise ValueError if it cannot be found: >>> [“item 1”, “item 2”, “item 3”].index(“not found”) Traceback (most recent call last): File … Read more

What is the fastest and pythonic way to generate a list [(0,0), (0,1), (0,2)…(0,100)]? [closed]

If you want a faster solution you can use itertools.repeat: from itertools import repeat: list(zip(repeat(0), range(101))) benchmark: %timeit [(0, x) for x in range(101)] # 3.64 µs ± 19.1 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) %timeit list(zip(repeat(0), range(101))) # 2.81 µs ± 35.3 ns per loop (mean ± … Read more

Adding iterations together in Java

In order to keep on adding the salary for each day and keeping the track of total for each day (as I get it from your statement), you can change:- total = amount * .01 * amount; to total += amount * .01 * amount; // total = total + (amount*0.01*amount) which(when not printing each … Read more

Iteration- Javascript [closed]

You can use a simple for-loop: document.write(“<h1>”); for (var i=namArLen-1; i>=0; i–) { document.write(namAr[i]); } document.write(“</h1>”); For simplicity, there’s also the reverse function on arrays: document.write(“<h1>”+namAr.reverse().join(“”)+”</h1>”);
