Create a set with the numbers that you need to delete and keep updating it while you read new lines. If the new line starts by one element in the set skip it and do not write it to the output file. to_delete = set() with open(‘input_file’, ‘r’) as input_file, open(‘output_file’, ‘w’) as output_file: for … Read more
Try using ast.literal_eval: import ast s=”{(76034,0),(91316,0),(221981,768),(459889,0),(646088,0)}” print(dict(ast.literal_eval(‘[‘ + s.strip(‘{}’) + ‘]’))) Output: {76034: 0, 91316: 0, 221981: 768, 459889: 0, 646088: 0} solved Convert a string representation of a set of tuples to a dictionary [duplicate]
Ah I see your problem. this is really what i want to do. i want to add tt1 in another list but the thing is this just happen [0, [102, 0.5, 0.591, 0.529, 10, 42, 26, 6, 8, 17, 24], 1, 27, 109, 0.41100000000000003, 0.308, 0.818, 16, 48, 26, 13, 9, 9, 22 When you … Read more
You are looking for the enumerate function: https://docs.python.org/2/library/functions.html#enumerate For instance: with open(“newfile.txt”, “w”) as output: for index, line in enumerate(open(“myfile.txt”)): output.write(“%d %s” % (index + 1, value)) 1 solved How can I use python to add index numbers for the data saved in the text file [duplicate]
At very simple i make this program for you as per your requirement that user must enter 10 numbers and program finds either it is prime or not. try this: for i in range(0, 10): num = int(input(‘Enter Number:’)) if num > 1: # check for factors for i in range(2, num): if (num % … Read more
Surfaces doesn’t have an object for retrieving the file name, but maybe you could use another variable to hold the file name? #load images bg_filename = “start.png” background = pygame.image.load(bg_filename) #keep looping through while 1: #clear the screen before drawing it again screen.fill(0) #draw the screen elements screen.blit(background, (0,0)) #update the screen pygame.display.flip() #loop through … Read more
Assuming that the count result applies to the whole file you can use a collections.Counter: from collections import Counter with open(‘input.tsv’) as infile: counts = Counter(infile.read()) for c in ‘SF’: print ‘{}: {}’.format(c, counts.get(c)) This has the advantage of allowing you to obtain counts of any character (not just “S” and “F”) with one pass … Read more
Maybe do some Exploratory data analysis first to see if you can figure out a pattern between your target variable and features? It would also be good to extract some features from your date/time variables rather than using them as integers (like weekday_or_not, seasons etc.) You can also try transforming your features (log, sqrt) to … Read more
Use regex a=”HOW TO COOK RICE – Chapter 1: 1 rinse water once 2 add one and a half cup of water for every cup of rice 3 cover the pot and simmer” idx=[i.start() for i in re.finditer(‘(\d{1,} \w{1,})’, a)] if idx: print(a[:idx[0]]) else: print(a) for i,index in enumerate(idx): if not i==len(idx)-1: print(a[index:idx[i+1]]) else: print(a[idx[i]:]) … Read more
This is using glob rather than listdir, but this might be a possible method. No regular expressions involved here either though. import glob folder_path = “C:\Temp” file_pattern = “\*.txt” search_string = “hello” match_list = [] folder_contents = glob.glob(folder_path + file_pattern) for file in folder_contents: print(“Checking”, file) read_file = open(file, ‘rt’).read() if search_string in read_file: match_list.append(file) … Read more
GtkAda is also object-oriented, and so is any other high-level GUI toolkit I’ve seen so far, so I don’t think you can avoid object-oriented programming for the GUI, unless you use a more low-level approach. Two more low-level approaches are: An HTTP/HTML based interface. Using the X protocol to talk directly with an X server. … Read more
