I have a loop starting with for i in range(0, 100). Normally it runs correctly, but sometimes it fails due to network conditions. Currently I have it set so that on failure, it will continue in the except clause (continue on to the next number for i).
I am finding problems in when I should use a while loop or a for loop in Python. It looks like people prefer using a for loop (less code lines?). Is there any specific situation which I should use one or the other? Is it a matter of personal preference? The codes I have read so far made me think there are big differences between them.
Here’s my code:
I have a function that evaluates input, and I need to keep asking for their input and evaluating it until they enter a blank line. How can I set that up? while input != '': evaluate input I thought of using something like that, but it didn’t exactly work. Any help? Answers: Thank you for … Read more
If x doesn’t implement an __iadd__ method then the x += y statement is just a shorthand for x = x + y. This would be the case if x was something like an int.
I have a list in a loop and I want to skip 3 elements after look has been reached.
In this answer a couple of suggestions were made but I fail to make good use of them:
I want to loop through a Python list and process 2 list items at a time. Something like this in another language: for(int i = 0; i < list.length(); i+=2) { // do something with list[i] and list[i + 1] } What’s the best way to accomplish this? Answers: Thank you for visiting the Q&A … Read more
I’m quite new to Spark and I’m trying to implement some iterative algorithm for clustering (expectation-maximization) with centroid represented by Markov model. So I need to do iterations and joins.
In C, I would do this:
I know how to use both for loops and if statements on separate lines, such as:
