If I want to add a break to my for or while loop at certain iteration can it be done without adding counter?
i=1
for line in zip(*input):
print(format_row.format(*line))
if i > 3: break
i += 1
also without enumerate():
for i, line in enumerate(zip(*input)):
print(format_row.format(*line))
if i > 3: break
EDIT:
Please solution without including additional libraries.
I don't want to use enumerate because i have to edit code in for statement too much, its a temporary break for example to print N number of lines rather than 1000 lines, so debugging can be fast. I want to add quick break and then remove it without need to modify original code of for loop.
I want to add 2 lines maximum one outside the for loop another inside the for loop, how to make this work, function will be stored elsewhere and reused many times so its not a problem, function can be as long as required.
# function does not count as extra code because it is reusable
def check(num):
if num > 3:
return True
else:
num += i
# line 1
i = 1
for line in zip(*input):
print(format_row.format(*line))
# line 2
if check(i): break
You could add a
range()zipped to your iterator, thus limiting your loop without the addition of lines or break statements.
