[ad_1] This is a Python3 example I got from https://www.kite.com/python/answers/how-to-check-if-a-network-port-is-open-in-python import socket a_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) port = 8080 location = (“127.0.0.1”, port) check = a_socket.connect_ex(location) if check == 0: print(“Port is open”) else: print(“Port is not open”) 1 [ad_2] solved Check If Port is Open in Python3?
[ad_1] I can’t test it since you didn’t provide a working example, but the first thing I notice is that you increment trow after you add the row, so the last row is trow – 1. Since you’ll need to decrement it anyway just do that before you try to delete. def delete_row(): trow -= … Read more
[ad_1] Sorry for the confusion regarding my previous answer. The problem was that you were appending n instead of i in myList.append(n). Moreover, you could simply use sum to sum your list. Your output was wrong because you were appending the number n and hence when you do sum=sum+myList[i], you were just adding n to … Read more
[ad_1] Some questions like that should really be accompanied by the real intention behind the code. The reason is that some problems should be solved completely differently. In the body of the script, the return can be used to quit the script. From another point of view, you can just remember the situation in a … Read more

[ad_1] valueChanged is a signal of Foo itself, so you should use self.valueChanged.connect(self.do_something) instead of self.t.valueChanged.connect(self.do_something). After all, the value that should be emitted with the signal is determined when the signal is emitted, not when connecting the signal to a slot.

[ad_1] Your error is probably that you forgot to cast the input(…) to int: start_year = input(‘Enter start year’) start_year = int(start_year) you should do the same for end_year and output. Note: It’s really hard to try to help you without the source code. I need to infer a lot of things to help you … Read more
[ad_1] Likely, what you want is: access = input(‘Type the key you want’) Even though the print() function displays outputs to your terminal, it doesn’t return anything, hence why print(access)->None 1 [ad_2] solved How to not see “None” output when getting user input(): input(print(“Your key:”))

[ad_1] Here’s something you can try. It uses a collections.defaultdict or collections.Counter to count High, Med and Low for each product, then merges the results at the end. from collections import defaultdict, Counter product_issues = [ {“product”: “battery”, “High”: 0, “Med”: 1, “Low”: 0}, {“product”: “battery”, “High”: 1, “Med”: 0, “Low”: 0}, {“product”: “battery”, “High”: … Read more

[ad_1] Problem is you are trying to send a array that is a python list. At first you need to convert it into nampy array. import numpy as np py_list = [439, 301, 481, 194, 208, 415, 147, 502, 333, 86, 544, 353, 229] convert_numpy = np.array(py_list ) sent = sent[np.convert_numpy,:] and for 1st line … Read more
[ad_1] In words, the process you’re doing says “zero out the flags for all multiples of this number.” The if statement says “do the next step only if the current number is a prime.” The second sieve has to zero out all multiples of 2, then 3, then 4, … for every number in the … Read more
