Every python tutorial: forget doing it yourself, here’s a library for you 😂

[aion]

"Here's a nifty trick someone else made for you."

[tragczny]

This should've really been a for loop instead

for c, s in cycle(lights):
print(c)
time.sleep(s)

[jayturner]

while True:
for stage, timer in lights:
print(stage)
sleep(timer)

[perstry]

Increase your build size just to write 1 line of code instead of 2

[lances]

while True:
for light in lights:
print(light[0])
time.sleep(light[1])

[SalticHash]

With that speed of the lights I'd be dead in a car crash

[ree]

while True:
for a, b in lights:
print(a)
time.sleep(b)

[aleksanderpanasiuk]

wouldn't that be simpler:

while True:
for light, duration in lights:
print(light)
time.sleep(duration)

[stikosek]

Or just use a for loop instead of including another library lol

[rljpdx]

this is pretty cool. i occasionally will use additional variables to a function as flags to control how the function functions. most people will just create another function, rightly so, instead of shoehorning 'flags' to a function to control how the function operates. (i do this occasionally when i have almost identical functions and want to cut down on duplicated code). now though this doesn't directly correlate to this, i can see in my mind a world of ideas now that i know this (thank you) as well as giving me more insight into just how flexible 'itertools' is. thanks again.

Mom says "while true" is a bad thing

[sebastianlondono]

How does it stop, in a while loop, does it make it fault at the end of the code, to break while true?

[hamzaomari]

without importing the library, just use generators with yield c, s for each one

[beanureeves]

python users importing libraries to do literally one thing: "im so smart"
everyone else in literally every language in programming: "sir, have you tried the shift+5 key on your keyboard?" (hint: it makes a % symbol!!1!1!!111!1)

[YuraSuper]

i love itertools. every function is so useful! that could have been just a nested while and for loop though.

[aggi]

The issue is that you're cycling, opposite to how a traffic light works, it goes back and forth so something like this would be better for that purpose:

import time



lights = {"Green":2,
"Yellow":0.5,
"Red": 2}



lights2 = ["Green", "Yellow", "Red"]


i = 0
while True:
try:
print(lights2[i])

i += 1
except IndexError:
i -= 2
print(lights2[i])

i -= 1

[gamatek]

from time import sleep
lights = [("Green", 2), ("Yellow", 0.5), ("Red", 2)]
i = 0
while True:
i = (i + 1) % 3
c, s = lights[i]
print(c)
sleep(s)

Need to print something?
