I am trying to re-run a nested for loop within a while loop if the while condition is not met. If the condition is met then I want the inner loop to terminate and proceed to the next iteration of the outer loop. I want to try the inner loop 10 times before preceding to the next i of the outer loop. I've tried various variations of the following (psuedocode) but am unsure exactly what the if / else statements at the end the function should say, break/continue? And where they should be indented to accomplish this. I've appended the indentation lengths to each part of the code. I would be grateful if anyone can help explain if it's possible to do this and how to do it. Thanks in advance.
def function(input):
counter1 = 0
for i in range(0, 10): #indent5 - outer loop
#assign some stuff to variables based on value of i...
counter2 = 0
var1 = cats[i]
var2 = dogs[i]
x = len(input)
MAX_RETRIES = 10
attempts = 0
while attempts < MAX_RETRIES and counter2 < x: #indent9
for var in var1 : #13 - inner loop
if blah == blah: #indent17
#do a lot of stuff here with cats and dogs...
random.choice(etc, etc)
#nested ifs
if blahblah == blahblah: #indent21
counter1 += 1
if blahblahblah == blahblahblah: #indent21
counter2 += 1
if at end of inner loop counter2 == x: #indent where?
#go to next iteration of OUTER loop
break / continue ? #?
else: #indent where?
#repeat INNER loop - how?
break / continue ?
#reduce counter1 by value of counter2
counter1 -= counter2
#reset counter2 to 0 to start inner loop again
counter2 = 0
return blah
I don't know what your code is doing but sometimes code may need the same if in two places - to exist inner for-loop and to exit outer while-loop (and skip rest of code)
while attempts < MAX_RETRIES and counter2 < x: #indent9
for var in var1 : #13 - inner loop
if blah == blah: #indent17
#do a lot of stuff here with cats and dogs...
random.choice(etc, etc)
#nested ifs
if blahblah == blahblah: #indent21
counter1 += 1
if blahblahblah == blahblahblah: #indent21
counter2 += 1
# exit `for`-loop
if counter2 == x:
break
# exit `while`-loop
if counter2 == x:
break
#reduce counter1 by value of counter2
counter1 -= counter2
#reset counter2 to 0 to start inner loop again
counter2 = 0
It can be also created with one break and with inverted condition in second if
because while ... counter2 < x will exit it when counter2 == x
while attempts < MAX_RETRIES and counter2 < x: #indent9
for var in var1 : #13 - inner loop
if blah == blah: #indent17
#do a lot of stuff here with cats and dogs...
random.choice(etc, etc)
#nested ifs
if blahblah == blahblah: #indent21
counter1 += 1
if blahblahblah == blahblahblah: #indent21
counter2 += 1
# exit `for`-loop
if counter2 == x:
break
# inverted condition
if counter2 != x:
#reduce counter1 by value of counter2
counter1 -= counter2
#reset counter2 to 0 to start inner loop again
counter2 = 0
If this part of code would be in separated function then it could use single return inside if blahblahblah == blahblahblah: instead of two break in two places.
But it would need to send many parameters to function.
