I have this code that checks internet connection and sets a boolean accordingly. I've put the code in a function. But PyCharm is showing that this line: "start_time = time.time()" is unreachable. Did I write my code wrong?
Screenshot: 
The code:
from time import time, sleep
import os
def something():
while True:
sleep(2 - time() % 2)
ip_list = ['8.8.8.8']
for ip in ip_list:
response = os.popen(f"ping {ip}").read()
if "Received = 4" in response:
print(f"UP {ip} Ping Successful")
_connected = True
print(_connected)
else:
print(f"DOWN {ip} Ping Unsuccessful")
_connected = False
print(_connected)
start_time = time.time()
seconds = 1
while True:
current_time = time.time()
elapsed_time = current_time - start_time
if elapsed_time > seconds:
print("Finished iterating in: " + str(int(elapsed_time)) + " seconds")
break
something()My end goal here is to understand why PyCharm would call this warning. It seems to me that everything is correct.
