How can I iterate through two lists in parallel?
I have two iterables in Python, and I want to go over them in pairs:
iterator
What exactly are iterator, iterable, and iteration?
What is the most basic definition of “iterable”, “iterator” and “iteration” in Python?
Removing from a list while iterating over it
The following code:
Why can’t I iterate twice over the same data?
Why can’t I iterate twice over the same iterator?
How to build a basic iterator?
How would one create an iterative function (or iterator object) in python?
Modifying list while iterating
Python 3.0 range() now behaves like xrange() used to behave, except it works with values of arbitrary size. The latter no longer exists.
How can I iterate over files in a given directory?
I need to iterate through all .asm files inside a given directory and do some actions on them.
Get the first item from an iterable that matches a condition
I would like to get the first item from a list matching a condition. It’s important that the resulting method not process the entire list, which could be quite large. For example, the following function is adequate:
Iterate over all pairs of consecutive items in a list
Given a list l = [1, 7, 3, 5] I want to iterate over all pairs of consecutive list items (1,7), (7,3), (3,5), i.e. for i in xrange(len(l) – 1): x = l[i] y = l[i + 1] # do something I would like to do this in a more compact way, like for x, … Read more
How does zip(*[iter(s)]*n) work in Python?
s = [1,2,3,4,5,6,7,8,9] n = 3 zip(*[iter(s)]*n) # returns [(1,2,3),(4,5,6),(7,8,9)] How does zip(*[iter(s)]*n) work? What would it look like if it was written with more verbose code?
