According to PEP-343, a with statement translates from: with EXPR as VAR: BLOCK to: mgr = (EXPR) exit = type(mgr).__exit__ # Not calling it yet value = type(mgr).__enter__(mgr) exc = True try: try: VAR = value # Only if “as VAR” is present BLOCK except: # The exceptional case is handled here exc = False … Read more

Use the following extension method to break the input into subsets public static class IEnumerableExtensions { public static IEnumerable<List<T>> InSetsOf<T>(this IEnumerable<T> source, int max) { List<T> toReturn = new List<T>(max); foreach(var item in source) { toReturn.Add(item); if (toReturn.Count == max) { yield return toReturn; toReturn = new List<T>(max); } } if (toReturn.Any()) { yield return … Read more
you can use startswith() eg for line in open(“file”): li=line.strip() if not li.startswith(“#”): print line.rstrip()
From the documentation for Skip: Bypasses a specified number of elements in a sequence and then returns the remaining elements. So you just need this: foreach (var item in list.Skip(1))
Use a slice, like below: with open(‘yourfile.txt’) as f: lines_after_17 = f.readlines()[17:] If the file is too big to load in memory: with open(‘yourfile.txt’) as f: for _ in range(17): next(f) for line in f: # do stuff
What you have here are two stream pipelines. These stream pipelines each consist of a source, several intermediate operations, and a terminal operation. But the intermediate operations are lazy. This means that nothing happens unless a downstream operation requires an item. When it does, then the intermediate operation does all it needs to produce the … Read more
With new Java 8 Stream API it actually becomes very elegant. Just use skip() method: cars.stream().skip(1) // and then operations on remaining cars
Python’s unittest module has a few decorators: There is plain old @skip: from unittest import skip @skip(“Don’t want to test”) def test_something(): … If you can’t use @skip for some reason, @skipIf should work. Just trick it to always skip with the argument True: @skipIf(True, “I don’t want to run this test yet”) def test_something(): … Read more
You’ll need tail. Some examples: $ tail great-big-file.log < Last 10 lines of great-big-file.log > If you really need to SKIP a particular number of “first” lines, use $ tail -n +<N+1> <filename> < filename, excluding first N lines. > That is, if you want to skip N lines, you start printing line N+1. Example: … Read more
