3 janv. 2017 · Always gets my hackles up. += in my mind should be an in-place modification. If you can't do it, don't appear to be doing it. I'm not the Python spec though, and clearly whatever my opinion, it does what it's defined to do. And it's not an objectively sane complaint anyway - integers are mutable and you can += them easy enough, which again ...
I had this doubt while I was trying to solve a graph-related problem. The issue I had was I needed to define an empty adjacency list and wanted to initialize all the nodes with an empty list, that's when I thought how about I check if it is fast enough, I mean if it will be worth doing a zip operation rather than simple assignment key-value pair.
18 févr. 2018 · When I run this code, it gives None instead of the 'Python' getting appended to the List. Why is that so?
9 août 2015 · 2. You don't need any iteration. Just do this: Horizontally: print "Monty Python". Output: Monty Python.

Since Z is less than a, the bits that represent the string are again lower than the bits that represent the other. In the last one, the first four letters match, but the fifth compares y with a, and a obviously comes first and thus is less.
18 mars 2019 · in python we also have a feature to index from the last. let us say. my_word = 'hello world'. print(my_word[-1]) # prints 'd'. # - stands from last starting with index 1. print(my_word[-4:]) # prints 'orld'. # if you know the length you can directly use. print(my_word[7:]) # prints 'orld'. This feature helps you to print the values indexing ...
11 nov. 2015 · 1. I'm trying to understand this solution of the Monty Hall problem, I understand most of the code, but am stuck on two pieces. Below is the code, but specifically I'm stuck on these two parts. result[bad] = np.random.randint(0,3, bad.sum()) and the entire switch_guess function. If anyone could explain in plain English for me that would be awesome.

28 févr. 2012 · We can use this function to split the string into chunks of n characters. import textwrapdef split_string_into_groups(s: str, n: int) -> list[str]: """ Splits a string into groups of `n` consecutive characters. This function uses the `textwrap.wrap()` function from the `textwrap` module to solve the problem.
13 janv. 2015 · If you define functions in .pdbrc they will only be available from the stack frame from which pdb.set_trace () was called. However, you can add a function globally, so that it will be available in all stack frames, by using an alternative syntax: def cow (): print ("I'm a cow") globals () ['cow']=cow. I've tested that it also works in place of ...
