python for loop single line
Write a proper comprehension, without append. >>> [i for i in range(10)] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> list(i for i in range(10)) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]. , As described in the question's answers that I've linked as duplicate to your question: Python list comprehension: test function return. You'd create a generator (or a list) that produces the (intermediate) results of your function's calls, Each time next() is called, the generator resumes where it left-off (it remembers all the data values and which statement was last executed). Generators are similar to List Comprehension that you use with square brackets instead of brackets , but they ar,You are producing a filtered list by using a list comprehension. i is still being bound to each and every element of that list, and the last element is still 'three' , even if it was subsequently filtered out from the list being produced. You shou, What you are using is called a list comprehension in Python, not an inline for-loop (even though it is similar to one). .... visited = [] for i, v in enumerator(vm): if i not in visited: p.append(q.index(v)) else: p.append(q.index(v,max(visited))) # this, The best source of information is the official Python tutorial on list comprehensions. List comprehensions are nearly the same as for loops (certainly any list comprehension can be written as a for-loop) but they are often faster than using a for loop. L, for line in results: print line. Using Python 3.0 print function with list comprehension: from __future__ import print_function [print(line) for line in results]., In your example, you try to collapse two levels of blocks / indentation into a single line, which is not allowed. You can only do this with simple statements, not loops, if statements, function definitions etc. That said, for your example there is a work,Simplify your Python loops. If you're like most programmers, you know that, eventually, once you have an array, you're gonna have to write a loop. Most of the time, this is fine and dandy, but sometimes you just don't want to take up the multi,It also creates an opportunity for perverse fun: attempting to get a Python program down to 1 line of code. Python is pretty simple to learn, but there are some weird hooks in it that allow you to twist it in ways it wasn't meant to be used. For examp
