Convert back and forth between strings and ints, make use of sum(). >>> def foo(n): n = str(n) if len(n) == 1: return int(n) return foo(sum(int(c) for c in n)) >>> foo(1969) 7 >>> def foo(n): n = str(n) if len(n) == 1: return int(n) return foo(sum(int(c) for c in n)) 2 solved RECURSIVE function … Read more
To give some example of what we mean, I think this is kind of alright import random import pickle class BaseCharacter: def __init__(self): self.gold = random.randint(25, 215) * 2.5 self.currentHealth = 100 self.maxHealth = 100 self.stamina = 10 self.resil = 2 self.armor = 20 self.strength = 15 self.agility = 10 self.criticalChance = 25 self.spellPower = … Read more
According to the official documentation, writelines writes a list of lines to a file. str(A) does not create a “list of lines” – obviously, when you print it to the screen – so the very first step should be to create a list-of-lines: A=[ [‘-‘, ‘A’, ‘B’, ‘C’, ‘D’, ‘E’], [‘A’, ‘0’, ‘5’, ‘6’, ‘7’, … Read more
Here’s a list comprehension that is equivalent to your nested loops: a = [[i * j for j in range(0, y)] for i in range(0, x)] 2 solved How to use list comprehension for the following code? [duplicate]
You’d still use enumerate(); you didn’t show how you used it but it but it solves your issue: for index, (value,num) in enumerate(sorted_list, start=1): print(“{}.\t{:<5}\t{:>5}”.format(index, value,num)) I folded your str.ljust() and str.rjust() calls into the str.format() template; this has the added advantage that it’ll work for any value you can format, not just strings. Demo: … Read more
You can use repr() for this purpose: print(repr(text)) This will also add quotes, and escape other characters like tabs, backspaces, etc. Other option is to replace the newlines: print(text.replace(‘\n’, ‘\\n’)) This will escape only line breaks and no other special characters. solved How can I Print \n after each sentence?
It creates a custom regex pattern – explanation as below Name (\w)\w* Name (\w)\w* Options: Case insensitive Match the character string “Name ” literally (case insensitive) Name Match the regex below and capture its match into backreference number 1 (\w) Match a single character that is a “word character” (letter, digit, or underscore in the active … Read more
The pandas command Series.plot.bar accepts a color keyword, where you can input a list of colors (in RGBA or color names). I’m not entirely sure on what logic does the command follow when the list is too short, but if the list is the right length, it’ll work. Example: %matplotlib inline import pandas as pd … Read more
I’ve rewritten this so it is easier to understand, splitting out complicated code, and removing unused lines: def record_disp(info): #define a function that takes the input data, info a=[list(x) for x in info] #turn the input list into a list of lists lens=[] # make an empty list to store max lengths #loop with x … Read more
You are looking for nested dictionaries. Implement the perl’s autovivification feature in Python (the detailed description is given here).

Barring a bug in asyncio, the issue is likely caused by a call to loop.stop() hidden somewhere in the code base. You probably want to remove or disable those, as they are fundamentally incompatible with run_until_complete, as well as with the more modern asyncio.run. solved Intermittent “Event loop stopped before Future completed.”
The name parm to open can be a variable so: fname = input(‘File to open ‘) f = open(fname, ‘w’) solved How to set a file name with a variable
What about to split the string and strip words punctuation, without forget the case? w in [ws.strip(‘,.?!’) for ws in p.split()] Maybe that way: def wordSearch(word, phrase): punctuation = ‘,.?!’ return word in [words.strip(punctuation) for words in phrase.split()] # Attention about punctuation (here ,.?!) and about split characters (here default space) Sample: >>> print(wordSearch(‘Sea’.lower(), ‘Do … Read more
It’s common question. Seems that you’re using cmd which doesn’t support unicode, so error occurs during translation of output to the encoding, which your cmd runs. And as unicode has a wider charset, than encoding used in cmd, it gives an error IDLE is built ontop of tkinter’s Text widget, which perfectly supports Python strings … Read more
