expandtabs() is used for setting the tab size and not replacing the spaces. However, you can use str.replace() to replace any given substring with another. txt = input(“Please type in your text here “) txt = txt.replace(‘ ‘, ‘…’) print(txt) solved Method which would prompt the user for input and then output that same input, … Read more
The best and shortest way to print multiline strings (ascii art) on the same line, even when the height is different in Python solved The best and shortest way to print multiline strings (ascii art) on the same line, even when the height is different in Python
In python, tuples are defined with tup = (val1,val2,…). This is what you’re doing when you define wholeAssDocumentation. Since tuples don’t have a re method, you’re getting that error. Other than that, I suggest you read the regex documentation because that’s not how you use a regex on a string either. Also you’re overwriting the … Read more
Here is an example of how to do what you are asking: # Create string of 81 uppercase letters string = ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ’*3 + ‘ABC’ # Assign each letter a number, and scale the numbers from 0 to 1 num = [(ord(string[char]) – 65)/25 for char in range(len(string))] # Assemble the numbers into a 9×9 matrix … Read more
For each value in the list, return it, if all the elements of the sublist have length less-than-or-equal-to 6 [x for x in mylist if all(len(y) <= 6 for y in x)] You can also create a list from the singular string elements, but unclear why you’d want this >>> simple_list=[‘apple’, ‘banana’, ‘cantaloupe’, ‘durian’] >>> … Read more
Try this : for dec_ldev in range(0,16777215): hex_ldev = hex(dec_ldev)[2:].zfill(6) print(“{}{}{}:{}{}:{}{}”.format(”,*hex_ldev)) 1 solved Generate a range of hex numbers in format [duplicate]
This is working under the assumption that the number of rows between the text is always consistent. # Open file, split on newlines into a list with open(‘file.txt’) as f: data = f.read().splitlines() # Break list into multiple lists 7 items long # this covers the text and the 6 sets of numbers that follow … Read more
You can solve it with requests (for maintaining a web-scraping session) + BeautifulSoup (for HTML parsing) + regex for extracting a value of a javascript variable containing the desired data inside a script tag and ast.literal_eval() for making a python list out of js list: from ast import literal_eval import re from bs4 import BeautifulSoup … Read more
The site you are accessing requires javascript and cookies. Urllib only provides support for cookies (with cookie jar). To get around the need for javascript, check out a library like selenium, and use it with phantomjs. pip install selenium Selenium with phantomjs is more powerful then urllib, but you pay the penalty of it being … Read more
If you want to do it your way: for i in range(1, 21): print(i, end=”,” if i!=20 else “” ) Output: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 But a better way of doing this would be: print(*range(1, 21), sep=”,”) solved How to remove the last comma?
No, there is no faster way of processing a file line by line, not from Python. Your bottleneck is your hardware, not how you read the file. Python is already doing everything it can (using a buffer to read the file in larger chunks before splitting into newlines). I suggest upgrading your disk to an … Read more
Your problem stems from poorly thought out and/or formatted path strings. Instead of concatenating raw strings, use os.path.join(). And make sure you’re always passing absolute paths. In that same vein, using string methods directly instead of “+” is often more efficient and usually more readable. With those in mind, working code: import os def rec(direc, … Read more
You should use im = ax.imshow() when you want add something to the existing axis, for example, a colorbar. If you don’t need to add anything to the axis, then it is fine to just use ax.imshow(). See this: https://www.geeksforgeeks.org/matplotlib-axes-axes-imshow-in-python/ Example from the link: c = ax.imshow(z, cmap =’Greens’, vmin = z_min, vmax = z_max, … Read more
Try: a = [(‘aa’, ‘bb’, [‘cc’, ‘dd’]), (‘ee’, ‘ff’, [‘gg’, ‘ff’])] def flatten(tup): lst = [] for x in tup: if isinstance(x, list): lst += x else: lst.append(x) return tuple(lst) output = [flatten(t) for t in a] print(output) # [(‘aa’, ‘bb’, ‘cc’, ‘dd’), (‘ee’, ‘ff’, ‘gg’, ‘ff’)] As you pointed out, applying How to make … Read more
when unpacking an iterable, the number of variables must match the values input being assigned. it depends on the values you are trying to unpack from the input. for instance, a,b= input() #12 print(a). #1 print(b). #2 You can easily unpack. However if you pass in more values than variable you will get an error. … Read more
