[ad_1] min1 = score_arr should be changed to min1 = score_arr[i]. min1 = score_arr is setting min1 to the whole list, so the next iteration fails on the line if score_arr[i] < min1 since score_arr[i] is a float and min1 is now a list (as indicated by the error message). But, a better way to … Read more
[ad_1] As @Aurora001 mentioned, you should not ask for completed code. However, I think addressing the method you might use could be a good answer to your question, and I hope others agree.

[ad_1] This should be fairly easy with something like the csv library, if you don’t want to get into learning dataframes. import os import csv new_data = [] for filename in os.listdir(‘./csv_dir’): if filename.endswith(‘.csv’): with open(‘./csv_dir/’ + filename, mode=”r”) as curr_file: reader = csv.reader(curr_file, delimiter=”,”) for row in reader: new_data.append(row[2]) # Or whichever column you … Read more
[ad_1] Your code fragment doesn’t make a lot of sense without more context. To get a better understanding of the keyword look at this: Use of “global” keyword in Python As for your code it makes the variable only available in a global scope after it errors which is unusual. As the warning indicates you … Read more
[ad_1] You’re not returning selection, you’re printing it instead. Replace print(selection) with return selection. 0 [ad_2] solved TypeError: ‘NoneType’ [duplicate]

[ad_1] Your dict is the wrong way round. The thing you want to look up (key) goes first in each pair pCode = {“T”: “Alberta”} a = input(“Enter a 6 character postal code: “) You can get the first character of the post code as a[0] print(pCode.get(a[0])) [ad_2] solved First character in a dictionary Python … Read more
[ad_1] This program should behave as you wanted: with open(“test.txt”,’r+’) as f: # Read the file lines=f.readlines() # Gets the word word=input(“Enter the word:”) print(word+” occured on line(s):”,end=’ ‘) # Puts a flag to see if the word occurs or not flag=False for i in range(0,len(lines)): # Creates a list of words which occured on … Read more
[ad_1] If I am assuming right and you are using from bs4 import BeautifulSoup you need to understand that find_all is part of the bs4.element.Tag object findAll might not work obj = BeautifulSoup(html_text, ‘html.parser’) obj.find_all(“tr”,{“class”:”match”}) This should solve your problem. 3 [ad_2] solved when I write findAll it says: findAll is not defined [closed]

From there on, it’s just a loop that counts how many of these you’ve encounteres: begin = int(input(‘Enter begin: ‘)) end = … Read more
[ad_1] Here’s a silly one-liner version: def print_table(seq, width=3): print(‘\n’.join([”.join( [(str(u[-i]) if len(u) >= i else ”).rjust(width) for u in seq]) for i in range(max(len(u) for u in seq), 0, -1)])) And here’s the same algorithm in a somewhat more readable form: def get_cell(u, i): return str(u[-i]) if len(u) >= i else ” def print_table(seq, … Read more
