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 solved Check If Port is Open in Python3?
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 -= 1 … Read more
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 the … Read more
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.

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. solved How to apply PyQt5 Event on a list with values instead of single … Read more
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 diagnosis … Read more

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”: 1, … Read more

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 sieve. … Read more
