Is there way to write an infinite for loop in Python?
for t in range(0,10):
if(t == 9): t= 0 # will this set t to 0 and launch infinite loop? No!
print(t)
Generally speaking, is there way to write infinite pythonic for loop like in java without using a while loop?
The itertools.repeat function will return an object endlessly, so you could loop over that:
import itertools
for x in itertools.repeat(1):
pass
To iterate over an iterable over and over again, you would use itertools.cycle:
from itertools import cycle
for t in cycle(range(0, 4)):
print(t)
This will print the following output:
0
1
2
3
0
1
2
3
0
1
...
You should create your own infinite generator with cycle
from itertools import cycle
gen = cycle([0])
for elt in gen:
# do stuff
or basically use itertools.count():
for elt in itertools.count():
# do stuff
cycle(_) (the underscore)?
NameError: name '_' is not defined.Just pass could help with forever true value.
while True:
pass
for i in range(0, 1, -1) : print("Hello")too doesn't work?
