Toggle Boolean value based on a triple state filter
Question:
I’m having a brain melting time with this. For some reason I thought it would be easier, but I’m struggling with this.
I have an application that a user can config before running based on desired parameters the user wants to test. There are 3 filters that the user can either turn on, turn off, or toggle.
If the user wants a filter on, he will set the filter in the configuration file to True. If the user wants it off, he sets it to False. If however, the user wishes to run the test with the filter on and than again off, he can set the configuration file to toggle
here are examples of filter1, filter2, and filter3 stored in a list.
toggle_state = ["toggle", "toggle", False]
toggle_state = ["toggle", True, "toggle"]
toggle_state = [False, "toggle", True]
toggle_state = [True, False, False]
...
Any combination should be available for testing purposes.
I have implemented nested while loops to accomplish what I’m attempting to do. However, I have had no real success. I have been able to make it work, with just toggle for all three filters.
I stripped out the functions related to my in a simple MUC script below.
#####CODE BLOCK 1######
import time
def toggle_filters():
toggle_state = ["toggle", "toggle", "toggle"]
# toggle_state = ["toggle", "toggle", False]
# toggle_state = ["toggle", "toggle", True]
# toggle_state = ["toggle", False, "toggle"]
# toggle_state = ["toggle", True, "toggle"]
# toggle_state = [False, "toggle", "toggle"]
# toggle_state = [True, "toggle", "toggle"]
filter_state = init_filters(toggle_state)
idx = 2
complete = 2
terminate = False
while True:
print(f"t{filter_state[0]:<5}{filter_state[1]:<5}{filter_state[2]:<5}")
### do something here with the filters ###
while True:
if toggle_state[idx] == "toggle" and not filter_state[idx]:
filter_state[idx] = True
break
elif complete < -1:
terminate = True
break
elif toggle_state[idx] == "toggle" and idx == len(toggle_state) - 1:
filter_state[idx] = False
if complete != 0:
filter_state[complete] = False
complete -= 1
if complete < 0:
idx = 1
else:
idx = complete
continue
elif toggle_state[idx] == "toggle" and idx != len(toggle_state) - 1:
if complete == 0 and idx == 0:
idx += 1
idx += 1
if terminate:
break
def init_filters(toggle_state):
"""..."""
filters = []
for idx in toggle_state:
if idx == "toggle":
filters.append(False)
else:
filters.append(idx)
return filters
if __name__ == "__main__":
toggle_filters()
however, when I’ve attempted to add in static values for the filters, it all goes to hell. I updated the toggle_filter() function to start looking for filters that are not set to toggle.
####CODE BLOCK 2####
import time
def toggle_filters():
# toggle_state = ["toggle", "toggle", "toggle"]
toggle_state = ["toggle", "toggle", False]
# toggle_state = ["toggle", "toggle", True]

# toggle_state = ["toggle", True, "toggle"]
# toggle_state = [False, "toggle", "toggle"]
# toggle_state = [True, "toggle", "toggle"]
filter_state = init_filters(toggle_state)
idx = 2
complete = 2
terminate = False
while True:
print(f"t{filter_state[0]:<5}{filter_state[1]:<5}{filter_state[2]:<5}")

filter_state[idx] = False
if complete != 0:
filter_state[complete] = False
complete -= 1
if complete < 0:
idx = 1
else:
idx = complete
continue
elif toggle_state[idx] == "toggle" and idx != len(toggle_state) - 1:
if complete == 0 and idx == 0:
idx += 1
idx += 1
elif toggle_state[idx] != "toggle" and idx == len(toggle_state) - 1:
if complete != 0:
pass
complete -= 1
if complete < 0:
idx = 1
else:
idx = complete
continue
elif toggle_state[idx] != "toggle" and idx != len(toggle_state) - 1:
if complete == 2 and idx == 2:
complete = 1
idx = complete
if complete == 1 and idx == 1:
complete = 0
idx = complete
else:
idx -= 1
if terminate:
break
def init_filters(toggle_state):
"""..."""
filters = []
for idx in toggle_state:
if idx == "toggle":
filters.append(False)
else:
filters.append(idx)
return filters
if __name__ == "__main__":
toggle_filters()
Which fails each time, and honestly I imagine I’m approaching this from the wrong direction, just based on the shear number of conditions I have to set. Does anyone have any suggestions as to what I should be looking at?
UPDATE:
if you take the first block of code, it will run as is. The output will look like a truth table.
0 0 0
0 0 1
0 1 0
0 1 1
1 0 0
1 0 1
1 1 0
1 1 1
This is when you set the filters to all toggle.
I’ve updated the second code block as a complete MUC.
here the output looks like this
0 0 0
0 1 0
1 1 0
however it should look like this
0 0 0
0 1 0
1 0 0
1 1 0
depending on which filter you set static, the ouputs are not correct.
Answers:
This gives the same output with less complication. itertools.product is a function that gives you all the combinations of each state listed. A TOGGLE filter can be zero or one, while a FALSE or TRUE state only provides a zero or one state, respectively.
Does this manage the states you want?
import itertools
TOGGLE = [0,1]
FALSE = [0]
TRUE = [1]
def toggle_filters(toggle_state):
for state in itertools.product(*toggle_state):
print(*state)
toggle_filters([TOGGLE, TOGGLE, TOGGLE])
print()
toggle_filters([TOGGLE, TOGGLE, FALSE])
Output:
0 0 0
0 0 1
0 1 0
0 1 1
1 0 0
1 0 1
1 1 0
1 1 1
0 0 0
0 1 0
1 0 0
1 1 0
